Low-frequency sounds are the bane of any recording studio, home theater or anechoic chamber. Finding a solution that will effectively control these sounds without resorting to calling in a professional soundproofing expert can feel like a challenge, until now.

Soundproof Cow 6” white acoustic foam bass wedge is the solution you need for echo control and bass reduction in your sound-sensitive environment.

These striking white foam pieces are extremely effective at low-frequency sound control. Measuring 12” x 12”, the 6”-thick foam is cut into a V pattern to increase bass-trapping surface area and allow the wedge to capture as much unwanted echo and bass as possible.

Installation of our 6” white Udderly Quiet Class A Bass Wedge is simple. You will not require any special tools, and they mount to most surfaces. With 24 to a case, you should have more than enough to cover your entire studio with echo-absorbing foam.

If you have used our bass wedge soundproofing products before, you may be familiar with our high-quality polyurethane, and you may be aware that its UL94 HF-1 flammability rating is not suitable for every environment. That is why our Class A base wedges are made not from polyurethane, but from heat-resistant melamine.

Melamine is much better suited to harsher environments and is not likely to combust from a few sparks or a temperature increase. In fact, our melamine foam wedges resist heat up to 482 degrees Fahrenheit.

Rest assured that we have not sacrificed any function in order to achieve this environmental resistance. The Noise Reduction Control (NRC) factor of our melamine foam is equivalent to our polyurethane products so you can install these with confidence.

This 6” white Udderly Quiet Class A Bass Wedge is everything you have been looking for in a low-frequency sound absorber that you can use yourself, and that can meet most building fire code requirements for exposed materials. Let us help you complete your soundproofing solution by rushing you a case of our white Class A Bass Wedges. 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
