This is the speaker that won Stereo Mojo,s coveted Speaker of the Year for 2009 and now significantly improved with new active bass system. These were original passive models that I recently went through completely and installed the new sub amps. The Cabernets fantastic performance is even better now and is much easier to drive. Features the unmatched Accuton ceramic mid range driver which covers the range of 80 hz - 4000 hz for a coherency not found in many other top line speakers. Split ribbon tweeter offers delicate ribbon highs with a dispersion pattern more like a a dome tweeter. Bass frequncies are dramticly enhanced with the new sub amps and can be tailered to fit differing tastes and rooms. Speakers come with jumpers to connect bass amps properly so just hook your speaker cables up to binding posts like a traditional speaker and you are good to go. When the bass is perfectly balanced the whole soundstage expands and locks in. Go to the link below for reviews and more information on this fabulous speaker, www.vaughnloudspeakers.com.
