Proprietary cast wool /carbon Quiet Cone woofers, and (3)  1” neodym silk dome tweeters provide wide coverage and exceptional rear/side field characteristics. By grouping 3 tweeters in a controlled cluster, radiated power is uniform both vertically and laterally. In addition, far field power is significantly increased.  This makes the 255 TRI a star performer and THE ideal side and rear channel speaker for high end theater applications.

A rugged 1” wide aluminum mounting frame (not plastic) is fastened to a massive ¾” thick MDF baffle. The proprietary inner support trestle bar assembly is comprised of  ¾” thick rigid 13 ply birch  and couples, via ¼” steel bolts, to provide a resonant free support system. A significant improvement in performance is realized because the front baffle/wall interface DOES NOT “move”. 

A minimum phase optimized, hybrid HQ crossover completes the design.
