The top-of-the-line Suprema — a 4.5-way sealed Reference flagship with twin 20 mm and 38 mm silk-dome tweeters, a dual-driver 165 mm midrange, a 203 mm lower-midrange and four 203 mm woofers in a double-curvature lute-shaped column. Rear-firing tweeters and a back midrange add an ambient field, and the system pairs with two separate 380 mm subwoofer cabinets — a cost-no-object statement for the largest rooms.
