This black Vicoustic Vari Bass Stacker, available in matte finish, is made from lacquered MDF to combine two units of the Vari Bass Ultra. Bass frequency resonance is one of the most difficult acoustic issues to solve in any room. Until now, the most effective options have generally involved using bass traps that are specifically designed, or customized to fit the room. However, these solutions can often be expensive and invariably involve complex measuring procedures.
There's also little scope for flexibility if changes are made to the listening space, such as moving furniture or gear. Vari Bass Ultra (available separately) is designed for use in any professional recording space, home studio, or hi-fi room.
