Krix seismix 1 Specification Guide

The Seismix 1 subwoofer has been designed to complement existing Stereo or Home  
Theatre systems where size and placement of the subwoofer is an important consideration. 
The amplifier module and 10” bass driver are identical to that used in the Seismix 3, however 
they have been re-designed in a smaller enclosure to allow for installation in a cabinet or 
where there is a space restriction. The Seismix 1 is an Explosive Experience.
