    ATS Acoustics QRD Wood 7-Well Quadratic Residue Diffuser 23" x 23" x 6.5"

    Best Overall Diffuser for Precise Sound Scatter

    View on Amazon

    This QRD diffuser stands out for its precision CNC manufacturing, ensuring highly accurate sound scattering, which is vital for eliminating issues like comb filtering and flutter echo. Compared with the BXI 2D diffuser, it offers more targeted diffusion at mid frequencies, making it ideal for professional studios.

The natural wood finish adds aesthetic flexibility, allowing for painting or staining, and its effective frequency range from 325 Hz to 3 kHz provides broad coverage for critical listening environments.

    Pros:
    • High-precision CNC manufacturing ensures accurate, professional-grade diffusion
    • Effective from 325 Hz up to 3 kHz, covering critical frequency ranges
    • Ready to install with included hardware and customizable finish
    Cons:

    Our verdict
    “This diffuser is best suited for dedicated studio spaces where precision and durability outweigh ease of installation.”
  2. BXI 2D Quadratic Residue Wood Sound Diffuser Panel, 24 x 24 x 2.8 Inches

    BXI 2D Quadratic Residue Wood Sound Diffuser Panel, 24 x 24 x 2.8 Inches

    Best for Wideband Diffusion in Versatile Spaces

    View on Amazon

    This 2D Quadratic Residue diffuser offers broad frequency coverage from 410Hz to over 24kHz, making it a versatile choice for a range of environments, from home theaters to recording studios. Unlike the ATS QRD, which focuses on mid-range diffusion, this panel provides broadband scattering to address flutter echo and sound bounce-back across a much wider spectrum. Its eco-friendly wooden construction is durable, paintable, and easy to mount, adding to its DIY appeal. The main tradeoff is that it doesn’t absorb sound, so it should be paired with absorption panels in overly reflective rooms.

    Pros:
    • Exceptional broadband diffusion from 410Hz to 24.5kHz
    • Eco-friendly, paintable wood construction allows customization
    • Lightweight at around 9.3 pounds and straightforward to mount
    Cons:

    • Mounting hardware sold separately

    Best for: Home theater enthusiasts or DIYers wanting broad-spectrum diffusion with easy customization

    Not ideal for: Rooms that require sound absorption or noise blocking, since it only diffuses

    • Dimensions:24 x 24 x 2.8 inches
    • Coverage:4 square feet
    • Weight:9.3 pounds
    • Material:Wood
    • Diffuser Type:2D Quadratic Residue
    • Frequency Range:410Hz – 24,571Hz
    Our verdict
    “Ideal for spaces needing broad, broadband diffusion where aesthetic flexibility and DIY customization are priorities.”
  3. Wood Sound Acoustic Absorber Diffuser Panel 23.6×23.6×3.2 inches – Combines Diffusion and Absorption for Music Studio Wall and Ceiling

    Wood Sound Acoustic Absorber Diffuser Panel 23.6×23.6×3.2 inches - Combines Diffusion and Absorption for Music Studio Wall and Ceiling

    Best for Studio Environments Needing Combined Diffusion and Absorption

    View on Amazon

    This hybrid panel offers both diffusion and absorption, making it well-suited for professional studios seeking to tame echoes and diffuse sound simultaneously. Its Helmholtz design enhances diffusion, while the fiberglass core provides effective sound absorption. Compared with purely diffusive panels like the TroyStudio diffuser, this option excels in rooms where reducing reverberation and maintaining a lively sound stage are both priorities. However, the fiberglass material means careful handling during installation and limited color options may affect aesthetics. Its slightly larger size (23.6″ square) helps cover more area efficiently.

    Pros:
    • Combines diffusion and absorption for versatile sound control
    • Effective Helmholtz design improves sound diffusion
    • Made with eco-friendly fiberglass and easy to install
    Cons:
    • Fiberglass material requires careful handling and safety precautions

    Best for: Music producers and studio owners who need a balanced approach to diffusion and absorption

    Not ideal for: Casual home users or spaces where aesthetic variety is more important than sound treatment

    • Dimensions:23.6 x 23.6 x 3.2 inches
    • Material:Fiberglass, wood
    • Color:Walnut
    • Installation:Concealed hardware included
    Our verdict
    “This panel suits professional or semi-professional studios aiming for a balanced acoustical treatment with aesthetic appeal.”
  4. Acoustic Diffuser Wall Art, Black, 24″x24″x2″

    Acoustic Diffuser Wall Art, Black, 24"x24"x2"

    Best for Decorative Diffusion in Multi-purpose Rooms

    View on Amazon

    This wall art diffuser combines visual appeal with sound diffusion, making it suitable for spaces where aesthetics matter alongside acoustics. Its geometric pattern scatters sound waves effectively, reducing reverberation and echo, similar in function to TroyStudio panels but with a more artistic presentation. Unlike the ATS QRD, which provides precise mid-frequency diffusion, this panel primarily addresses general sound bounce-back and adds a decorative element. Its lightweight plastic construction and included mounting tape make installation straightforward, though it offers no sound absorption properties.

    Pros:
    • Visually appealing design doubles as wall decor
    • Lightweight and easy to install with included tape
    • Effective at reducing echoes and reverberation in casual settings
    Cons:
    • Provides diffusion only, no sound absorption or noise blocking
    • Limited to decorative purposes, less precise diffusion control

    Best for: Home users or creative spaces wanting decorative diffusion without complex installation

    Not ideal for: Rooms needing significant sound absorption or professional-grade diffusion

    • Size:24″ x 24″ x 2″
    • Material:Polylactic Acid (PLA) filament
    • Pieces Included:9
    • Mounting:Double-sided tape included
    Our verdict
    “Perfect for enhancing room aesthetics while improving sound clarity in casual or multipurpose spaces.”
  5. TroyStudio Acoustic Sound Diffuser Panels, 19.7 X 19.7 X 1 inches 12 Pcs White PVC Plastic 3D Wall Panel, Recording Studio Acoustical Treatment Diffusion panel, Art Decorative Ceiling Tiles

    TroyStudio Acoustic Sound Diffuser Panels, 19.7 X 19.7 X 1 inches 12 Pcs White PVC Plastic 3D Wall Panel, Recording Studio Acoustical Treatment Diffusion panel, Art Decorative Ceiling Tiles

    Best Budget Diffuser with Artistic Appeal

    View on Amazon

    This set of PVC diffuser panels offers a cost-effective solution for rooms needing diffusion, with a modern 3D geometric pattern designed to scatter sound waves in multiple directions. Compared to the ATS QRD or BXI panels, these are lighter (around 0.69 pounds each) and easier to install, making them suitable for DIY projects or spaces with limited mounting options. However, their diffusion range is less targeted, and they do not provide absorption, so they work best in rooms where reducing echo is the main goal rather than full sound treatment. Their white color and lightweight design make them versatile for decorative or functional use.

    Pros:
    • Affordable and lightweight, easy to handle and mount
    • Modern geometric design enhances room aesthetics
    • Effective at scattering sound waves to reduce echo
    Cons:
    • Less precise diffusion compared to dedicated QRD panels
    • Does not absorb sound or block noise

    Best for: Home studios or streaming rooms seeking affordable diffusion with decorative flair

    Not ideal for: Professional control rooms requiring precise diffusion or sound absorption

    • Size:19.7 x 19.7 x 1 inches
    • Quantity:12 pieces
    • Material:PVC plastic
    • Coverage:Approx. 32.34 sq ft
    • Color:White
    • Weight per panel:0.69 pounds
    Our verdict
    “This diffuser set offers a practical and decorative solution for casual spaces aiming to improve sound clarity without breaking the budget.”
  6. ATS Acoustics QRD Wood 7-Well Quadratic Residue Diffuser, 23 x 48 x 6.5 Inches

    ATS Acoustics QRD Wood 7-Well Quadratic Residue Diffuser, 23 x 48 x 6.5 Inches

    Best Overall for Balanced Diffusion

    View on Amazon

    This 7-well QRD diffuser excels at dispersing sound evenly across a broad frequency range, making it ideal for controlling reflections in larger studios or listening rooms. Compared to the smaller TroyStudio panels, its larger size and seven wells provide more comprehensive diffusion, especially in the midrange from 325 Hz to 3 kHz. However, its substantial weight of 39 pounds demands sturdy mounting and enough wall space, which could be a challenge in smaller or less robust setups. Its durable multi-ply radiata pine construction, with a paintable finish, offers both aesthetic flexibility and long-term resilience. The inclusion of hardware simplifies installation, but the panel’s size and weight may limit placement options in confined spaces. This diffuser makes the most sense for those seeking a robust, high-performance solution to reduce comb filtering and flutter echo in sizable rooms.

    Pros:
    • Provides broad diffusion from 325 Hz to 3 kHz, improving sound clarity
    • Helps reduce comb filtering and flutter echo effectively
    • Heavy-duty, paintable wood construction ensures durability and aesthetic flexibility
    • Includes mounting hardware for straightforward installation
    Cons:
    • Heavy at approximately 39 pounds, requiring secure mounting
    • Large size may limit placement options in small or cluttered rooms
    • Recommended listening distance may be challenging in tight spaces

    Best for: Medium to large studios or listening rooms requiring broad, effective diffusion across a wide frequency range.

    Not ideal for: Small rooms or spaces with limited wall space where a heavy, large diffuser might be impractical.

    • Dimensions:22-7/8 x 47-3/4 x 6.5 in
    • Weight:39 lbs
    • Material:Multi-ply radiata pine wood
    • Frequency Range:325 Hz to 3 kHz
    • Manufacturer:ATS Acoustics
    • Mounting Hardware:Included
    Our verdict
    “This diffuser suits larger rooms where robust, wide-range diffusion is a priority and space is ample.”
  7. Wood Acoustic Sound Diffuser – 23.6″ x 23.6″ x 3.2″ Acoustic Wall and Ceiling Panel for Music Studio, Theater

    Wood Acoustic Sound Diffuser - 23.6" x 23.6" x 3.2" Acoustic Wall and Ceiling Panel for Music Studio, Theater

    Best for Versatile Aesthetic and Broadband Diffusion

    View on Amazon

    Compared with bulkier options like the ATS QRD diffuser, this panel offers a more manageable size while still providing effective sound scattering across 430Hz to 2730Hz. Its 3D Quadratic Residue design creates a visually appealing texture that doubles as a diffusion tool, making it suitable for both walls and ceilings in smaller to medium-sized spaces. The natural pine wood finish is eco-friendly and paintable, allowing customization to match room decor. The panel’s weight of 12 pounds makes it easier to install with standard mounting hardware, though multiple units may be needed for larger rooms. Its broadband diffusion reduces echoes and standing waves, enhancing clarity without absorbing too much sound. This panel is ideal for users who want a decorative yet functional diffusion solution that fits a variety of room sizes and styles.

    Pros:
    • Effective broadband diffusion from 430Hz to 2730Hz
    • Natural, eco-friendly pine wood that’s paintable and durable
    • Lightweight and easy to install with included hardware
    • Aesthetic design enhances room decor
    Cons:
    • Limited coverage area per panel, requiring multiple for larger rooms
    • Requires screw mounting—no adhesive option available
    • May need extra panels to achieve desired diffusion in bigger spaces

    Best for: Home studios or small theaters seeking a stylish, effective broadband diffuser that can be customized.

    Not ideal for: Large commercial spaces or rooms with extensive sound treatment needs, due to its moderate coverage area.

    • Dimensions:23.6 x 23.6 x 3.2 in
    • Coverage Area:3.87 sq ft
    • Weight:12 lbs
    • Material:Natural pine wood
    • Diffusion Range:430Hz – 2730Hz
    • Design:3D Quadratic Residue diffuser
    Our verdict
    “This diffuser balances aesthetic appeal and sound performance, making it ideal for smaller rooms where style matters.”
  8. TroyStudio Acoustic Sound Diffuser Panels, 19.7 X 19.7 X 1 inches 12 Pcs Black PVC Plastic 3D Wall Panel, Recording Studio Acoustical Treatment Diffusion panel, Art Decorative Ceiling Tiles

    TroyStudio Acoustic Sound Diffuser Panels, 19.7 X 19.7 X 1 inches 12 Pcs Black PVC Plastic 3D Wall Panel, Recording Studio Acoustical Treatment Diffusion panel, Art Decorative Ceiling Tiles

    Best for Affordable, Decorative Diffusion with Quick Installation

    View on Amazon

    Compared with larger wood diffusers like the ATS QRD, TroyStudio’s panels focus on affordability and ease of setup with self-adhesive backing, making them suitable for quick upgrades in smaller rooms. Their compact size of 19.7 inches square and lightweight design (less than 1 pound per panel) allow for flexible placement without the need for screws or heavy mounting hardware. The irregular geometric patterns scatter sound effectively across a broad spectrum, improving soundstage width and depth, especially in home studios or gaming rooms. However, the adhesive’s reliance on smooth surfaces limits placement options on textured or uneven walls, and these panels primarily scatter rather than absorb sound, so they won’t reduce room reverberation as much as foam or thick panels. This pick is ideal for those seeking an affordable, decorative diffusion layer that can be installed in moments.

    Pros:
    • Self-adhesive backing enables tool-free, quick installation
    • Lightweight and flexible for easy placement
    • Decorative geometric design enhances room aesthetics
    • Effective at scattering sound for improved soundstage
    Cons:
    • Adhesive may not adhere well to textured or uneven surfaces
    • Primarily scatters sound rather than absorbing it
    • Limited coverage per panel, requiring multiple units for larger areas

    Best for: Home users or hobbyists needing quick, tool-free diffusion enhancement with visual appeal.

    Not ideal for: Rooms with textured or uneven walls where adhesive might not hold well, or spaces requiring high absorption in addition to diffusion.

    • Material:MDF + PU
    • Color:Black
    • Panel Size:20 x 20 x 6 inches
    • Quantity:2 panels
    • Coverage:5.4 sq ft
    • Installation:Self-adhesive
    Our verdict
    “This set offers an economical and quick diffusion upgrade, especially suited for aesthetic-focused home environments.”
  9. Acoustic Wood QRD Diffuser, 7-Well Quadratic Residue Panel for Wall and Ceiling, 23.6 x 23.6 x 3.2 in

    Acoustic Wood QRD Diffuser, 7-Well Quadratic Residue Panel for Wall and Ceiling, 23.6 x 23.6 x 3.2 in

    Best for Precise Reflection Control in Small to Medium Rooms

    View on Amazon

    This 7-well QRD diffuser is designed for precise sound scattering, making it especially suitable for small to medium-sized studios or listening rooms. Its CNC-cut natural pine wood construction ensures consistent performance and an attractive appearance. While similar to the ATS diffuser, this panel’s slightly smaller size at 23.6 inches square makes it easier to place in tighter spaces, although it still requires secure mounting due to its weight of 9.5 pounds. Its focused frequency range effectively reduces flutter echoes and improves clarity, but it may need multiple panels to cover larger areas for effective diffusion. The natural wood finish adds aesthetic warmth, but handling and installation require some care due to the material’s fragility during mounting. This diffuser is perfect for precise, targeted diffusion where space is limited.

    Pros:
    • Precise control of sound reflections with 7 wells
    • Made from attractive, CNC-cut pine wood
    • Effective at reducing flutter echoes for clearer sound
    • Includes mounting hardware for straightforward setup
    Cons:
    • May require multiple panels for larger areas
    • Natural wood may require careful handling during installation
    • Limited coverage compared to larger diffusors

    Best for: Small to medium-sized rooms needing accurate sound wave scattering with a natural aesthetic.

    Not ideal for: Large rooms or spaces where extensive diffusion coverage is required, as multiple panels may be needed.

    • Dimensions:23.6 x 23.6 x 3.2 in
    • Weight:9.5 lbs
    • Material:Natural pine wood
    • Design:7-well QRD
    • Frequency Range:Not specified
    • Manufacturing:CNC cut
    Our verdict
    “This diffuser is well-suited for targeted reflection control in smaller rooms where aesthetic quality matters.”
  10. Sirius 2D QRD Acoustic Studio Diffuser (2 Pack), 20″x20″x6″, Cherry

    Sirius 2D QRD Acoustic Studio Diffuser (2 Pack), 20"x20"x6", Cherry

    Best Overall for Versatile Acoustic Shaping

    View on Amazon

    This pair of 2D quadratic residue diffusers stands out for their ability to scatter sound waves across a broad frequency range, from 625Hz to 5000Hz, effectively balancing diffusion and reflection. Unlike the single-panel BXI Wood Diffuser, the Sirius pack offers double coverage, making it more suited for larger or irregularly shaped rooms. Its combination of diffusion, reflection, and absorption creates a lively yet natural sound environment without making rooms sound dry or boxy. The 6-inch thickness may be a drawback for spaces with limited depth, and the coverage per panel is modest, requiring multiple packs for extensive areas. Still, its decorative cherry finish adds aesthetic appeal. This pick is ideal for those wanting a flexible, visually appealing solution that improves soundstage and room perception without sacrificing style.

    Pros:
    • Effective across a wide frequency spectrum (625Hz-5000Hz)
    • Combines diffusion, reflection, and absorption for versatile control
    • Includes mounting brackets for easy wall installation
    • Decorative cherry finish doubles as wall art
    Cons:
    • Relatively thick profile (6 inches) may not fit all spaces
    • Coverage per panel is limited to 5.4 sq ft, so multiple packs are needed for larger rooms

    Best for: Home recording studios or music rooms needing broad, versatile acoustic treatment with aesthetic appeal.

    Not ideal for: Small, low-ceiling spaces or rooms requiring extensive coverage on a tight budget, due to its thickness and limited coverage per panel.

    • Dimensions:20x20x6 inches
    • Material:Laminated MDF and Acoustic Foam
    • Coverage Area:5.4 sq ft per panel
    • Quantity:2 panels
    • Frequency Range:625Hz to 5000Hz
    • Finish:Cherry
    Our verdict
    “This diffuser set offers a balanced, decorative solution ideal for medium to large rooms seeking comprehensive acoustic management.”
  11. BXI Wood Sound Diffuser 24 x 24 x 2.8 in Acoustic Diffusion Panel

    BXI Wood Sound Diffuser 24 x 24 x 2.8 in Acoustic Diffusion Panel

    Best for Aesthetic and Broadband Diffusion

    Compared with the Sirius diffuser, the BXI Wood diffuser offers a narrower profile at just 2.8 inches thick, making it a better fit for rooms with limited space. Its broad diffusion range from 544 Hz to over 24,500 Hz ensures more comprehensive sound dispersal, particularly benefiting spaces where high-frequency clarity is essential. Constructed from eco-friendly, paintable wood, it adds warmth and style that can be customized to match decor. However, it only covers 4 square feet per panel and disperses sound rather than absorbing noise, so it’s not suitable for reducing overall room reverberation. The mounting hardware is sold separately, which could add inconvenience. This diffuser works best for those wanting a decorative, broadband diffusion element in a stylish, eco-conscious package.

    Pros:
    • Wide broadband diffusion (544 Hz to 24,571 Hz)
    • Eco-friendly, paintable wooden construction
    • Slim profile (2.8 inches) suits tight spaces
    • Suitable for wall or ceiling mounting
    Cons:
    • Does not absorb sound or reduce noise levels
    • Mounting hardware is sold separately
    • Limited coverage per panel requires multiple units for larger areas

    Best for: Music or listening rooms where aesthetic integration and broad high-frequency diffusion are priorities.

    Not ideal for: Rooms needing noise reduction or substantial sound absorption, since it disperses rather than absorbs sound and covers only 4 sq ft per panel.

    • Dimensions:24 x 24 x 2.8 inches
    • Material:Wood
    • Coverage:4 sq ft
    • Frequency Range:544 Hz to 24,571 Hz
    • Mounting Hardware:Sold separately
    Our verdict
    “This diffusion panel excels in adding high-frequency dispersion and aesthetic appeal in spaces where space is limited and style matters.”

Factors to Consider When Choosing Acoustic Diffuser Panels For Mixing Room

Choosing the right acoustic diffuser panels for your mixing room involves considering several factors beyond basic specifications. Understanding how size, material, and design influence sound diffusion will help you make an informed decision. It’s also important to think about your room’s size, shape, and existing acoustics to select panels that complement your setup. Proper placement and size of diffusers can dramatically improve sound clarity, so avoid rushing into the cheapest option without assessing your specific needs.

Diffusion Performance and Design

Effective diffusion depends on the design of the panels, with quadratic residue diffusers (QRDs) being among the most popular for mixing rooms. They scatter sound waves broadly, reducing flutter echoes and standing waves. Look for panels with multiple wells or chambers as these tend to diffuse sound more evenly across frequencies. Be aware that larger, multi-well diffusers typically perform better but may require more installation space. Avoid overly small or simplistic designs if your goal is to create a balanced, professional sound environment.

Size and Coverage

The size of the diffuser panels directly impacts how much of your room they can influence. Larger panels cover more area and diffuse sound more broadly, which is essential in bigger rooms. Conversely, smaller diffusers can be strategically placed in tight spaces or as accents, but they may not provide enough coverage for larger areas. Consider your room’s dimensions and where you plan to install diffusers to prevent gaps in coverage that could weaken your acoustic treatment.

Material and Durability

Materials like wood and high-quality plastics are common in diffuser panels. Wood offers a natural aesthetic and reliable diffusion, but it can be heavier and more expensive. Plastic panels tend to be lighter and easier to install, especially in DIY setups, but may not have the same aesthetic appeal or longevity in humid environments. Think about your studio’s environment and maintenance preferences when choosing materials to ensure your panels last over time.

Aesthetic and Style

Diffusers come in a variety of styles, from traditional wooden designs to artistic wall art panels. Your choice should align with your studio’s decor and your preference for visibility. Artistic panels can double as wall decor, creating a more inspiring workspace, but they might not diffuse sound as effectively as purpose-built QRDs. Balance the desire for aesthetics with acoustic performance to achieve the best overall setup.

Price and Value

Prices vary widely, reflecting differences in size, materials, and design complexity. While high-end diffusers can deliver superior diffusion, they often come with a hefty price tag. Budget options can still provide decent diffusion but may require more careful placement or supplemental treatments. Assess your budget against your room size and acoustic goals—sometimes investing a little more yields significantly better results that last longer and look more integrated.

Frequently Asked Questions

Are diffusion panels better than absorption panels for a mixing room?

Diffusion panels serve a different purpose than absorption panels; they scatter sound waves to create a more even sound field, reducing flutter echoes and standing waves. Absorption panels, on the other hand, dampen reflections to control reverberation. In a mixing room, a combination of both is often ideal—diffusers help maintain some lively sound, which is crucial for accurate mixing, while absorbers reduce excessive reflections. The choice depends on your room’s specifics and the sound you want to achieve.

Can I install diffusion panels on my ceiling?

Yes, diffusion panels can be installed on ceilings to improve sound distribution throughout your space. Ceiling-mounted diffusers are especially useful in rooms where sound waves tend to bounce downward or where wall space is limited. However, ensure that the panels are properly supported and that their size and weight are suitable for ceiling mounting. Proper placement is key to maximizing their effectiveness without causing installation issues.

How do I know what size diffuser panels I need?

The size depends on your room’s dimensions, the areas you want to treat, and your acoustic goals. Larger panels typically diffuse sound over broader areas, making them suitable for bigger rooms or as focal points. Smaller panels are useful for targeted diffusion or decorative accents. As a rule of thumb, panels should be placed at ear level or strategic points where sound reflections are most noticeable. Consulting a room layout or acoustic professional can help determine the optimal size and placement.

Are wooden diffuser panels better than plastic or synthetic options?

Wood panels generally offer superior diffusion qualities and a natural aesthetic that many prefer in studio settings. They tend to be more durable and can blend seamlessly into professional environments. Plastic or synthetic diffusers are lighter, often more affordable, and easier to install, making them popular for DIY setups. However, they may not last as long under humid conditions and might lack the visual appeal of wood. The best choice depends on your budget, environment, and aesthetic preferences.

How should I place diffuser panels in my mixing room?

Diffusers are most effective when placed at reflection points—typically on the wall directly opposite your speakers or at first reflection points on side walls. For optimal diffusion, panels should be positioned at ear level when seated in your mixing position. Avoid cluttering small spaces with diffusers that are too large; balance coverage with room size. Proper placement ensures the sound waves scatter evenly, improving clarity and stereo image during mixing.

Conclusion

For those seeking a reliable, all-around performer, the ATS Acoustics QRD Wood 7-Well Diffuser offers excellent diffusion and durability. Budget-conscious buyers will appreciate the BXI 2D Quadratic Residue Diffuser for its affordability and performance. If aesthetics matter, the Acoustic Diffuser Wall Art provides stylish design without compromising too much on sound diffusion. For beginners, a smaller, easy-to-install panel like the TroyStudio Diffuser Panels simplifies setup. Advanced users with larger rooms should consider bigger, multi-well diffusers for comprehensive coverage. Ultimately, your choice depends on room size, budget, and whether aesthetics or performance take priority.
