RealTraps (New Milford, Conn.) offers its new membrane trap: MiniTraps ($159.99).
Absorbing midrange and high frequencies, MiniTrapsare small and easy to handle, and because they are made withrigid Fiberglas and metal instead of foam, they are fire-resistant.
According to RealTraps co-owner Ethan Winer, "The main problem in most studios and listening rooms is standing waves that cause severe variations in the low-frequency response. Many engineers and audiophiles cover their walls with foam, which just makes the room too dead at mid and high frequencies, while doing nothing for the low end. MiniTraps are much more absorbent than foam at low frequencies, so they do a superior job overall and with fewer pieces. Their light weight and small size also makes them ideal for larger installations like churches and auditoriums. Best of all, they install easily with one nail or hook without glue or wall damage."
