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

999999 in stock




Sound-sensitive rooms require effective soundproofing solutions. If you have a home theater, professional recording studio, anechoic chamber or other location where low-frequency sounds are creating unwanted interference, you need the right product to capture and absorb those noises, leaving you with clean sound to record or enjoy.

A simple and effective solution is our 8”-thick gray acoustic foam bass wedge. With eight inches of sound-absorbing power in a V-cut 12” x 12” foam wedge, each one of these pieces will do an excellent job of capturing the echoes and bass reverberations that have been ruining your sound quality. The gray color makes it easy for these wedges to blend into most environments, and with 16 to a case per order, you can distribute them as needed to deal with all the unwanted low-frequency noise in your studio.

Our acoustic foam bass wedges are easily mounted to most surfaces as the V-cut pattern creates more surface area and opportunities to trap harsh sound, so it doesn’t end up in your ears or on your recordings.

Traditionally, Soundproof Cow has offered high-grade polyurethane acoustic foam with a flammability rating of UL94 HF-1. However, polyurethane is not suitable for all environments. That’s why we make these acoustic foam bass wedges out of melamine foam with a Class A™ flammability rating. You get all the soundproofing power in a wedge that is heat-resistant up to 482 degrees Fahrenheit.

While you should never expose any soundproofing foam to flame, these 8” gray Udderly Quiet Class A Bass Wedge packs are a great alternative to polyurethane foam. You may need an alternative when you are soundproofing an environment that is at risk for exposure to sparks or high heat, or one where building fire codes for exposed materials prohibit the use of polyurethane foam. Our Class A melamine foam passes most building fire code requirements.

If you have a room that requires clean, clear sound, there’s no time to waste. Order your cases of 8” gray Udderly Quiet Class A acoustic foam bass wedges right now.
