Developed for dealing with troublesome unwanted low-frequency sounds in anechoic chambers and recording studios, Soundproof Cow 6” gray acoustic foam bass wedge products are now available for anyone who needs quality bass reduction and echo suppression in any residential or commercial environment, from garage podcast studios to home theaters and more.

Our 6” gray Udderly Quiet Class A Bass Wedge is one of the simplest and most effective ways for you to control low-frequency sound. The 12” x 12” wedge pieces are simple to mount anywhere, attaching to most surfaces without special tools. They come in a neutral gray color to blend in with your studio environment, and the V-cut pattern is both aesthetically interesting and functional, creating more areas where echoes can become trapped within, keeping them safely away from your clean, clear sound.

You may have discounted the possibility of using our bass wedges before because you are soundproofing a temperature-sensitive environment. You may have been concerned that your foam wedges might catch fire. To be sure, although our polyurethane wedges have a flammability rating of UL94 HF-1, polyurethane is always flammable and not suitable for these environments. Fortunately, our Class A™ acoustic foam is different.

Our Class A™ acoustic foam bass wedges are made from heat-resistant melamine, not polyurethane. This means that while you still will not want to expose it to direct flame, you have much less to fear from unexpected sparks or temperature spikes. These melamine foam wedges are heat-resistant up to 482 degrees Fahrenheit.

The fact that they are so tough doesn’t mean you have to worry about a reduction in the quality of the sound absorption. In fact, our melamine wedges have a Noise Reduction Control factor (NRC) of 1.25, comparable to that of our polyurethane foam.

The 6” gray Udderly Quiet Class A Bass Wedge is a great solution when you need an echo absorber that can meet most building fire code requirements for exposed materials. With 24 to a case, you should have plenty of wedges to soundproof your studio in full. See them in action by ordering a case 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
