Are you getting the sound quality that you need in your small home recording studio or theater? If not, perhaps you should ask what you are doing about your corners — even if you already have soundproofing in your sound-sensitive room.

Corners are often neglected when it comes to soundproofing, but if you are experiencing unwanted low-frequency noise, they just may be the culprit. Two walls next to each other means a lot of stray sounds bouncing against each other, which can create plenty of echo and bass distortion.

Thankfully, there is a very easy solution to this problem, and Soundproof Cow has it. Our 24” charcoal acoustic foam corner bass traps are a perfect fit for small- to medium-sized studios, theaters and other sound-sensitive rooms that need a way to deal with harsh bass sounds emanating from the corners.

We sell these 24” charcoal acoustic foam bass trap corner pieces in packs of eight, and you can start using them right away. The charcoal color means they will blend in with most studio environments and the vertical fluting provides a distinctive touch, as well as improving the wedges’ soundproofing characteristics.

These are 12”x12”, two-foot-high, 17” thick wedges shaped to slide right into the corners of the room. You get eight to a pack so you can soundproof the corners of two sound-sensitive rooms or keep some in reserve for when you need them.

Our corner bass traps are made of Soundproof Cow’s superior polyurethane foam. This is high-quality material that won’t tear or rip or lose its shape or color for a long time to come — no installation is required. Just drop them in the corners and let them work. Make sure they are suitable under your building’s fire code regulations for exposed materials before using. They are rated UL94 HF-1 for flammability. Polyurethane should always be kept away from flame.

You may be amazed at how much cleaner your sound quality is after putting these acoustic foam bass corner traps to work. We can have them over to you right away, so order yours now.

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
