Original Corner Bass Trap Corner Kit Acoustic Studio Foam

Professional recording studios and control rooms — tri-corner treatment.
The Original Bass Trap Kit treats one tri-corner fully. The tri-corner is the point of greatest low-frequency energy accumulation in a room, and the kit provides the components to address it comprehensively. Pair with Slider wall tiles for a coordinated treatment package. Use the Coverage Calculator to determine the number of kits required — most rooms have four tri-corners, so four kits treat all four comprehensively.

Rehearsal rooms and live rooms — tri-corner low-frequency control.
The kit's combined Equivalent Absorption Area per object: 0.6 at 50Hz, 1.4 at 63Hz, 1.3 at 80Hz, 2.2 at 100Hz, 1.9 at 125Hz, and 2.2 at 160Hz addresses the low-frequency build-up that contributes to muddiness in musical performance. Treating the tri-corners first establishes the foundation for the rest of the acoustic treatment.

Coordinated treatment with Slider family tiles.
The Original profile of the bass traps pairs with the Slider 12" tile family, allowing the kit to be installed alongside Slider wall tiles for a coordinated acoustic treatment package with a consistent visual finish across walls, corners, and tri-corners.

Complete tri-corner treatment — cube in the tri-corner, three 3ft traps running off in three directions.
The Corner Bass Trap Kit provides the components to treat one tri-corner fully in a single purchase. The Bass Trap Corner Fill cube seats in the tri-corner junction, and the three 3ft Bass Traps run off from the cube in the three directions — along the two wall edges and the ceiling edge that converge at the tri-corner.

Original profile — matching Slider tile family aesthetic.
The Original profile of the bass traps pairs with the Slider 12" tile family, allowing the kit to be installed as part of a coordinated acoustic treatment package with a consistent visual finish across walls, corners, and tri-corners.

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.

Is the kit better value than buying the parts separately?

Yes. The kit costs less than buying the three 3ft traps and a Corner Fill individually, and it arrives as one matched set sized to treat a complete tri-corner. Choose individual traps instead if you want a different mix of lengths or are building a corner a piece at a time.

If I only buy one kit, which corner should it go in?

Fit it in one of the ceiling tri-corners at the speaker end of the room, where low-frequency energy tends to build up most. A typical rectangular room has four ceiling tri-corners, so four kits treat all of them. You don't need to buy them all at once but ideally you would install them in pairs. Add kits as budget allows, working from the front of the room back.

How heavy are the traps, and are they secure above head height?

Weights run from 1.0kg (2ft Wedge or Wave) to 2.8kg (3ft Quadrant). They are fixed with Advanced Acoustics Contact Adhesive on both the trap and the surface, which bonds on contact once touch-dry, so press each one firmly into position. For a fixing you can take down, mount the trap on MDF and hang it with mirror plates, which is the recommended method for wall–ceiling corners.

Will bass traps help with a boomy home cinema or subwoofer?

Yes, where the problem is bass building up in the room, which makes a subwoofer sound boomy or uneven from seat to seat. Corners are where that energy is strongest, so trapping the front and rear corners reduces the boom and evens out the bass. Traps won't change how much bass reaches the next room, and they don't treat dialogue clarity. Wall tiles or panels handle the mid and high frequencies.

What if one kit doesn't make enough difference?

All products carry a 30-day money-back guarantee. One kit treats one tri-corner, and most rooms have several, so the improvement grows as you treat more corners. If it hasn't helped enough, contact us with your room dimensions and we'll advise on where to add treatment before you consider a return. Call 01623 643609 or email info@advancedacoustics-uk.com.
