Vicoustic Ships Vari Bass Passive Bass Trap

Acoustic solutions manufacturer Vicoustic, based in Lisbon, Portugal, is shipping the latest addition to its variable acoustics product range. Vari Bass is designed to eradicate problems associated with low frequency resonance. Vicoustic states that it is the first passive, stand-alone tunable bass trap of its kind.

Vari Bass is designed for use in any professional recording space, home studio or hi-fi room. Made from wood and high-density acoustic foam, the bass trap can be tuned between 40 Hz and 100 Hz by simply rotating its wooden top (which has a series of resonant pots) until the problem disappears. A scale is included to show the exact frequencies on which Vari Bass is acting. The unit’s stand-alone structure enables it to be repositioned as required and used in different rooms.

“Everyone is aware of the problems caused by bass frequency issues and the amount of extra work involved in getting a mix right if those issues are not treated properly,” says Vicoustic developer Jorge Castro. “We are very excited about Vari Bass. It’s simple to use and really effective in those problem areas. Also, it’s a solution that is affordable enough to be used in all kinds of recording and listening spaces.”
