Dealing with low-frequency bass sounds can be a challenge in a number of environments. These sounds can be distracting and interfere with the clean sound you want, especially if you are in a sound-sensitive environment like a recording studio or home theater. One of the best solutions to this problem is bass-absorbing acoustic foam from Soundproof Cow.

However, it may be a challenge to fit this foam in the corners of your room, theater or studio. This is one of the biggest problem areas when it comes to unwanted sound. A corner where two walls meet creates the opportunity for low-frequency noises to bounce against each other and produce a harsh cacophony that mixes in with the sound you’re trying to enjoy.

If you have a larger room that needs sound control, try our 48” charcoal acoustic foam corner bass traps. Available in packs of four, these four-foot-high traps are bass wedges that are specially designed to fit into the corners of your studio, with a neutral charcoal color that will blend into almost any acoustic environment.

These 48” charcoal acoustic foam bass trap corner-shaped pieces are professional grade polyurethane bass wedges that are the perfect shape to capture all the low-frequency sounds in the corners of the room, trapping them inside so they don’t end up on your recording or in the ears of your guests.

The four-pack means each order provides you enough wedges to soundproof the corners of an entire room. Although you can mount them, no special tools are necessary. Just drop them into the corners, and you’re good to go.

These bass corner traps are of superior quality and will last and retain their shape and color for a very long time. They have a flammability rating of uL94 HF-1, which is appropriate for most environments, but verify this with your local fire codes and avoid exposing them to open flame.

Our 48” bass corner traps are a clear solution to the problem of big unwanted bass noise coming from the hard corners of your acoustic environment. Order yours and see for yourself today!

The times I talked with you on the telephone and corresponded through email you have been very helpful and efficient. I would highly recommend Soundproofcow.com to anyone!

– S. Cimino, PA

I have emailed a lot of different manufactures and I have to say your customer service is head and shoulders above all of them. I emailed your company at about 9pm my time and when I woke up the next morning you had already answered my question and then the follow up was a few hours later. I am impressed. Thanks a lot for the quick turn around!

– E. Gustafson, NV

I just wanted to send a quick thank you for your rapid response and helpfulness. I very much appreciated it. You have been responsive in every way all through the process. It has been a pleasure doing business with you and your company.

– T. Alexander, CA

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.

– Mike
