Fabric Options

Broadband are available in 15 standard fabric colors sourced from:

  • Guilford of Maine – Anchorage line
  • Burch Fabrics – Prime Time line

Both fabric lines are acoustically transparent, durable, and suitable for architectural interiors. There is no functional or acoustic difference between the two fabric options. They are used together to achieve our unique color palette.

Indoor Safety and Air Quality

All materials used in Broadband Panels are appropriate for indoor environments, including studios, homes, offices, schools, and houses of worship.

  • Fabrics are designed for interior architectural use
  • Materials meet the fire safety standards required for commercial installations
  • Mineral wool cores are fully encapsulated during construction to help contain fibers and maintain a clean, stable panel assembly

Broadband Panels are designed for straightforward installation and include 2" Z-Clips for standard wall mounting.

Panels can be installed on walls, ceilings, or straddling corners. Wall installations use the included 2" Z-Clips. For ceiling, corner, or suspended installations, we offer the following hardware options:

  • Corner Trap Installation Kit
  • Ceiling Panel Hardware Kit
  • Cloud Hardware Kit
  • Suspended Wall Panel Kit (for mounting panels in front of windows, built-ins, etc.)

Each hardware option includes step-by-step installation guides, available as downloadable PDFs.

Installing panels with an air gap can further enhance low-frequency absorption, depending on placement and room layout. For an easy and consistent way to add an air gap, see our Air Gap Spacer: https://www.musiccityacoustics.com/shop/p/air-gap-spacer

Broadband Panels: Built For Balance

Broadband Acoustic Panels are built for rooms where accuracy and balance matter most, including recording studios, mixing and mastering rooms, hi-fi listening rooms, home theaters, and worship spaces. At 4.5 inches deep, they effectively absorb 100 Hz and up through the frequency spectrum, targeting the low-mid range where most rooms struggle. This range includes the core of vocals, acoustic instruments, drums, and piano, and it’s where clarity is often lost to mud, masking, and distortion in untreated rooms. By controlling low-mid energy, Broadband Panels create a balanced foundation, improving detail, focus, and translation across the entire frequency spectrum. This is where great sound starts.

The Crux of Critical Listening

Broadband panels excel in any environment that needs extra precision.

Whether you're tracking vocals, mixing in a home studio, or mastering professionally, Broadband Panels give you the clarity and focus you need to make confident decisions. They control the low-mid range where vocals, guitars, and most instruments live, eliminating the masking and distortion that cloud your ability to hear what's really happening. The result: mixes that translate, recordings that capture cleanly, and a monitoring environment you can trust.

Modern worship services demand both clarity and energy. Broadband Panels installed on back walls and ceilings control the low-mid frequencies from live bands and PA systems while maintaining the warmth and impact congregations expect. Spoken word becomes more intelligible, music becomes more defined, and the space feels balanced instead of overwhelming.

Your system deserves a room that reveals its full potential. Broadband Panels eliminate the comb filtering, room modes, and low-mid buildup that mask the quality of your amplifiers, speakers, and source components. What you hear is what the artist intended: clear, focused, and immersive. Every detail, every layer, every note becomes more present and defined.

Cinematic sound requires more than powerful speakers. Broadband Panels control the reflections and low-mid buildup that cause dialogue to get lost and explosions to sound muddy. The result is clear dialogue, impactful bass, and an immersive experience where every sound effect and musical score sits exactly where it should. Your theater becomes a space you want to spend time in.

The Difference
You'll Feel

Broadband Panels don't just change how a room sounds. They change how it feels to work, listen, and create in that space.

You can hear exactly where vocals sit, where bass lives, and how instruments balance without second-guessing your choices.

What sounds good in your room sounds good everywhere else. Car, headphones, phone speakers—it all translates.

In listening rooms, you hear layers and details you've never noticed before. The soundstage opens up and instruments sit in their own space.

In home theaters, voices stay clear and intelligible even during action scenes and complex soundtracks.

Rooms feel more comfortable and inviting. You can work, listen, or watch for hours without strain


On a technical level, you'll measure reduced reverb time, flatter frequency response, and better low-mid control. But the human impact is what matters: you can finally hear the truth in your music, trust your decisions, and enjoy the space you've built.

Performance You Can Trust

We test every product at Riverbank Acoustical Laboratories, one of the most respected acoustic testing facilities in North America, following ASTM C423 standards. This ensures the performance data you see is independently verified and accurate, so when we list absorption at a specific frequency, you can trust the results.

  • X Axis = Frequency in Hz | Y Axis = NRC Rating from 0-1

    NRC stands for “noise reduction coefficient.” An NRC rating is a percentage grade that represents a specific panel’s ability to reduce noise. 

    Ratings are typically expressed in decimals from 0 to 1, where 0 represents 0% (meaning the product reflects sound) and 1 represents 100% (meaning the product absorbs sound)

    So, for example, if a panel has an NRC rating of .85, that means that roughly 85% of the sound that hits that panel’s surface will stop there

    Ratings can go above 1 because they’re calculated by scoring all of the surfaces of the product, leading to ratings like 1.05.

Installation Made Simple

Great acoustics start with proper installation. Our step-by-step guides walk you through every aspect of the process, from choosing the right hardware to placing panels for maximum impact. Whether you're mounting to walls, ceilings, or corners, we've designed the installation to be straightforward and confidence-building.

Why 100-200 Hz Changes Everything

The 100-200 Hz range is the core of most music and speech. Vocals, acoustic guitars, pianos, snare drums, and countless other instruments have their core energy in this range. When this range is left untreated, everything above it suffers. Low-mids mask the highs and upper-mids, creating a muddy, cloudy sound where instruments blur together instead of sitting clearly in the mix.

Broadband Panels at 4.5 inches deep absorb effectively down to 100 Hz, bringing clarity, focus, and resolution to this critical range. This isn't just about controlling bass. It's about revealing detail, improving separation, and creating a balanced frequency response that lets you hear what's actually happening in your room.

Thinner panels can't reach this range. Low Profile and High-Mid Panels work beautifully for their intended applications, but they don't have the depth to control the low-mids that define accurate listening environments. Broadband Panels bridge the gap between mid-range control and deep bass treatment, making them essential for studios, listening rooms, and home theaters.

Your Questions: Answered

  • If you're tracking and producing but not mixing critically, Broadband Panels give you excellent performance without the depth and cost of Bass Traps. If you're mixing or mastering and need accurate low-end translation, Bass Trap Panels become essential. Many studio designs use both: Bass Traps in corners and on the back wall, Broadband on sidewalls and the front wall.

  • Absolutely. Broadband Panels are ideal for home studios where space matters. At 4.5 inches deep, they deliver serious low-mid control without dominating your room. They're substantial enough for accurate monitoring, streamlined enough to keep your space functional.

  • Yes. Broadband Panels control the low-mid frequencies that cause dialogue to get lost and action scenes to sound muddy. They create a clearer, more balanced soundstage where every element sits exactly where it should.

  • It depends on the size of your room, ceiling height, and your specific goals. Studios typically need coverage on multiple walls and the ceiling. We offer free room layout designs to show you exactly what your space needs and where panels should be placed for maximum impact.
