All at once the possibilities of music, space and naturalness find its way into our newest product – Principal Grand.  Why Principal? Strength, power and beauty: principal refers technically to the most pure of sounds from an organ; that which is not an imitation of other instruments. Following with this traditional definition, the Principal Grand subwoofer should never be confused with a woofer but rather is built as an example of the truest form of Sub-Woofer.   Properly designed loudspeakers already have woofers. The Principal Grand subwoofer is designed to add the last octave of bass reinforcement below traditional woofers allowing for a greater sense of space and focus. Of course in home theater applications this also means the visceral experience the sound editors originally created and which are only now being realized with the latest high resolution multi-channel audio and video formats.
