Built for the Last 5-10%
The SubFreq™ Bass Trap was designed for rooms where accuracy and control are non-negotiable.
High-End Mix/Mastering Rooms
Mixing and mastering demand accuracy that most rooms can't deliver without serious treatment. SubFreQ panels control the 40-100 Hz range where kick drums, bass guitars, and synths live, giving you the clarity and decay time control needed to make confident decisions. Room modes get tamed, low-frequency buildup disappears, and transient response becomes tight and controlled. The result: your low end translates to every playback system, and you can trust what you're hearing.
Pro Recording/Production Studios
When you're tracking and producing at the highest level, your room needs to perform at the highest level. SubFreQ panels deliver the low-end control that lets you hear exactly what's happening in your recordings and productions without second-guessing your decisions. Early reflections, speaker boundary interference, and axial room modes all get controlled, creating a monitoring environment where accuracy and inspiration work together.
Reference Hi-Fi Listening Rooms
Reference-quality systems deserve reference-quality rooms. SubFreQ panels eliminate the room modes, decay time issues, and low-frequency distortion that mask the detail your equipment is capable of revealing. Bass becomes tight, controlled, and articulate. Soundstage opens up. Every layer, every transient, every note sits exactly where the artist and engineer intended. This is what your system has been waiting for.

The Difference You'll
Low frequencies stop hanging around longer than everything else. The room sounds tight, focused, and controlled instead of boomy and undefined.
The massive peaks and nulls that create frequency response chaos get tamed. Your room becomes accurate and trustworthy.
What sounds good in your room sounds good everywhere. Your mixes and masters translate to every playback system without surprises.
In audiophile rooms, bass is articulate and powerful. Soundstage opens up. Detail emerges that you've never heard before.
Results You Can See (and
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
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, straddling corners, or creating freestanding configurations, we've designed the installation to be straightforward and confidence-building.Not sure where to start?

Why Dual-Density Insulation and Open-Frame Construction Matter
SubFreQ uses dual-density insulation: 6 inches of 4 lb/ft³ Rockwool backed by 6 inches of R19 fiberglass. The Rockwool handles mid and upper frequencies. The fiberglass extends absorption into the deepest frequencies, controlling the 40-63 Hz range where kick drums, bass guitars, and synths carry their fundamental energy.
The open-frame construction is just as important. Traditional panels are enclosed on five sides. SubFreQ is open on all six sides, maximizing air particle velocity interaction and improving absorption efficiency across the low-frequency range.
This approach isn't new. World-class studios use dual-density insulation when building custom bass traps. SubFreQ brings those same principles into a prefabricated panel, making world-class performance accessible.

Your Questions:
-
SubFreQ is essential when you need maximum low-end control for mixing, mastering, or reference-quality listening. Bass Trap Panels work excellently from 63-80 Hz up, but SubFreQ delivers significantly more absorption from 40 Hz all the way up through 100 Hz. If you're mastering, working at the highest level, or building an audiophile listening room where the last 5-10% of performance matters, SubFreQ is the answer. If you're producing, tracking, or mixing without mastering-level requirements, Bass Trap Panels deliver professional results at lower cost and depth.
-
SubFreQ panels are versatile. They work on sidewalls for early reflection and speaker boundary interference control. They excel on the back wall for controlling front-to-back axial room modes (which carry the most energy). They're highly effective when straddling corners for maximum low-end absorption. They can mount to ceilings in rooms with adequate height. They can even be stacked freestanding to create massive absorption walls. The key is prioritizing locations where low-frequency control has the biggest impact: typically corners and the back wall first, then sidewalls and ceiling as needed.
-
Installing panels with an air gap increases effective depth and improves low-frequency absorption. However, at 12.5 inches deep, SubFreQ already delivers exceptional performance wall-mounted. Air gaps can still help, but the improvement is less dramatic than with thinner panels like Bass Trap or Broadband. The bigger benefit with SubFreQ comes from corner-mounting (straddling corners) rather than air gaps behind wall-mounted panels. That said, if you have the space and want maximum performance, air gaps still provide value.
-
Absolutely. SubFreQ's depth and open-frame construction make it ideal for stacking and freestanding configurations. You can create massive absorption walls by stacking multiple panels vertically or horizontally, then pulling them away from walls to create air gaps on all sides. This is one of the most effective ways to control low frequencies in studios and listening rooms where flexibility matters.
-
Each SubFreQ panel weighs approximately 30 lbs. While this is heavier than thinner panels, the weight is manageable with proper mounting hardware. The open-frame construction keeps weight reasonable despite the 12.5-inch depth.
-
It depends on your room size, dimensions, and goals. Mastering rooms and studios working at the highest level typically need substantial coverage: corners, back wall, sidewalls, and ceiling. Audiophile listening rooms benefit from similar coverage. The more SubFreQ coverage you have, the more controlled and accurate your low end becomes. We offer free room layout designs to show you exactly what your space needs and where panels should be placed for maximum impact.
