The ASC SubTrap is a powerful acoustic upgrade for your subwoofer. It looks like a subwoofer and acts like a "sub-stack", but is actually a base for your subwoofer that provides needed acoustic conditioning.

By raising the subwoofer off the floor and putting a bass trap in its place, the subwoofer is effectively decoupled from the vertical room mode. Excessive bass buildup is reduced and the playback volume of the subwoofer can be turned back up.

The ASC SubTrap provides for mode-, vibration-, and position-free playback. Now your subwoofer can play and be heard as it was meant to!

We are pleased to see a glowing review of the SubTrap in the September 2004 Stereophile. In his own words, writer Kalman Rubinson says the SubTrap is something most subwoofer owners will "have to have."
