Udderly Quiet™ Class A™ Bass Wedge 8″ White (Case of 16)

Environments where large numbers of people congregate demand Class A™ products rather than flammable polyurethane foams.

This professional grade acoustic foam product enhances the sound quality of any recording or listening environment.

Are you looking for the ideal soundproofing solution for your home theater, garage recording studio or other anechoic environment? Try the product that was formulated specifically for controlling low-frequency sounds in these situations. Our 8” white acoustic foam bass wedge product could be just the thing you need to get the clean, clear sound you’ve been seeking.

How do they work? Just install these 12” x 12”, 8”-thick wedges throughout your studio. You get 16 to a case, so feel free to install them liberally. Many people find the striking white color and V-cut shape offers great visual appeal. Installation is simple as the wedges mount to most surfaces and do not require any special tools to install.

The acoustic foam and the V-cut shape combine to suck in and trap the echoes that would normally interfere with your sound quality. The result is a cleaner sound with minimal distortion or harsh noises to foul your recording or distract your ear.

Our 8” Udderly Quiet Class A Bass Wedge products are made specifically for situations where polyurethane is not appropriate. Although usually fine for standard environments, our polyurethane products’ flammability rating of UL94 HF-1 may not pass very strict building fire codes for exposed materials. Our Class A™ wedges, made of heat-resistant melamine, usually will. If you have looked into polyurethane foam only to find it violates your building fire code, try this product instead.

These melamine foam wedges are heat-resistant up to 482 degrees Fahrenheit yet have equivalent Noise Reduction Control (NRC) properties to polyurethane. If your studio or theater is in a location where sparks are a possibility or very high temperatures can occur, our 8” Udderly Quiet Class A Bass Wedges may be a better choice than polyurethane foam.

Now that you know about our Class A bass wedges, you have no excuse for not giving your studio, theater or other sound-sensitive location the echo-free, clear-sound environment it deserves. Complete your studio soundproofing by ordering and installing 8” white Udderly Quiet Class A Bass Wedges 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
