Original Corner Bass Trap 2ft Acoustic Studio Foam

Professional recording studios and control rooms — corner low-frequency control.
The Original Corner Bass Trap 2ft addresses the low-frequency standing waves and bass build-up that wall and ceiling tiles do not effectively control. Install vertically in the wall-wall corners and horizontally in the wall-ceiling corners — the locations where low-frequency energy is greatest. The 2ft length is a modular unit: use a single trap where targeted treatment is required, or stack multiple traps to build the full corner coverage needed for the room. Pair with Slider wall tiles for a coordinated treatment package. Use the Coverage Calculator to determine the number of bass traps required.

Home studios and rehearsal spaces.
Low-frequency reverberation is a common problem in home studios and rehearsal rooms, contributing to muddiness and masking clarity in the recording. The Original Corner Bass Trap 2ft provides targeted corner treatment for these environments, controlling the low-end build-up that wall tiles leave unaddressed. The 2ft length is practical for smaller room dimensions where 3ft traps would be excessive.

Coordinated treatment with Slider family tiles.
The Original profile of the bass trap pairs with the Slider 12" tile family, allowing the bass trap to be installed as part of a coordinated acoustic treatment package with a consistent visual finish across walls and corners. The matching profile produces a unified aesthetic across the full installation.

Corner low-frequency control — Equivalent Absorption Area 0.5 at 160Hz.
The Original Corner Bass Trap 2ft provides targeted absorption at the low frequencies that wall and ceiling tiles do not effectively address. Equivalent Absorption Area per object: 0.2 at 50Hz, 0.3 at 63Hz, 0.2 at 80Hz, 0.3 at 100Hz, 0.4 at 125Hz, and 0.5 at 160Hz. Low-frequency absorption increases gradually with frequency across the measured range. Where stronger low-frequency absorption is required, the Original Corner Bass Trap 3ft provides greater EAA at most measured frequencies as a result of the additional length.

Installing our Corner Foam Bass Traps is very simple.  The first step to take is to work out your correct placement and preferred layout of bass traps.  Do a sketch on paper first to make sure that the layout looks right and you have enough bass traps and space for your planned design.

Once the acoustic foam bass traps are mounted they are hard to remove so it is important to get the layout right before you begin.  Once you have a sketch of the layout you plan you can then mark up the wall with the layout.  You can either use pencil, masking tape or lasers to layout the design.

When mounting the bass traps in the corners apply Advanced Acoustics Contact Adhesive to both the back of the bass trap and the mounting surface.  There is no need to heavily cover the bass trap or wall with adhesive, a band of adhesive around the perimeter of the bass trap along with 50% - 75% coverage of the rest of the bass trap will be fine.  Use the same equivalent amount on the wall.  Avoid overspray on the bass traps and the corners so that adhesive can’t be seen when they are in place.  Masking Tape on the wall will help with this.  If you do get webbing overspray on the bass trap, don’t touch it, allow it to dry, in most cases you will be able to peel the adhesive off.

The adhesive we supply is solvent based so we recommend that you keep all doors of the room and any windows open whilst completing the installation.

Should I choose the 2ft or the 3ft trap?

The 3ft trap is 915mm long against 610mm for the 2ft. Below 100Hz the two measure about the same. From 125Hz up the 3ft is clearly stronger: 0.6–0.7 at 125Hz against 0.4–0.5, and 0.9 at 160Hz against 0.5–0.7, depending on profile. Per metre of corner covered the 3ft is also slightly cheaper. Choose the 2ft where a run is short or where you need to finish a stack at the right height.

Will bass traps stop bass travelling through walls to my neighbours?

No. Bass traps absorb low-frequency energy inside the room, which reduces boom and uneven bass at the listening position. They don't stop sound passing through walls, floors or ceilings. Reducing what a neighbour hears needs mass and decoupling, such as Mass Loaded Vinyl, acoustic plasterboard and resilient bars or clips. Sort that first if it's your problem, then add bass traps to improve how the room itself sounds.

Does the profile (Wedge, Wave, Quadrant or Original) change the performance?

All four are 30kg/m³ polyurethane foam and perform very similarly. At 160Hz every 3ft profile measures 0.9. The small differences are lower down. The Quadrant is the heaviest profile at both lengths (2.8kg for a 3ft, against 1.6kg for the Wedge and Wave) and measures a little higher at 63–80Hz (0.4 and 0.3). The Wave measures highest at 100Hz (0.7). For most rooms, choose the profile that matches your wall tiles. If the lowest frequencies are your priority, the Quadrant has a slight edge.

Do I need acoustic tiles as well as bass traps?

For a complete treatment, yes. Bass traps control low-frequency build-up in the corners. Tiles control the mid and high frequency reflections off the walls and ceiling that cause echo and flutter. A room with traps only can still have a harsh, echoey top end. Our Studio Starter Kits combine both in one purchase.

What if my room still sounds boomy after fitting the traps?

All products carry a 30-day money-back guarantee. If the bass is less improved than you expected, the usual cause is coverage rather than the product: too few traps, or corners left untreated. Send us your room dimensions and a photo and we'll advise on layout before you decide whether to return anything. Call 01623 643609 or email info@advancedacoustics-uk.com.
