Top-of-the-line Suprema — a 4.5-way sealed Reference flagship with twin 20 mm and 38 mm silk-dome tweeters, dual-driver 165 mm midrange, 203 mm lower-midrange and four 203 mm woofers in a double-curvature lute-shaped main column. Two rear-firing tweeters and a back midrange add the ambient field; the system pairs with two separate 380 mm carbon-fibre sandwich subwoofer cabinets (500–2000 W) for full-range performance below 45 Hz.
