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

999999 in stock




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.
