The Trio line is purpose-built for on-wall mounting and matching to your flat panel video monitor.   Their enhanced performance versus the Duo line is courtesy of one additional driver in the left and right channel speakers-and two additional drivers for the center channel.  This prodigious power, combined with the benefits of Sonic Holography, High Back-emf drivers and cabinets featuring rosewood veneers covered with seven coats of hand-applied lacquer, make the Cinema Ribbon Trios the singular choice for every serious Home Theater devotee.
