MESSE12: 30dB Cut Speaker Isolation System

Grossmann lets you rock, but without complaints   23-Mar-12

No flash plug

    MP4 3:42 mins

Great demonstration of some well made speaker isolation cabinet technology. The Grossmann system, allows you to quickly change speakers or mics and to crank your amp, while keeping the outside volume a most reasonable -30dB down.


Great demo.
