Ascend Acoustics CMT-340 SE2 vs Sonus Faber Lumina II

The Ascend Acoustics CMT-340 SE2 is the more accurate pick. A dual woofer bookshelf speaker with accurate sound, high sensitivity, and lots of clean output, a superb partner for a subwoofer at a modest price. Its measured preference score, a predictor of how neutral it sounds, is 5.33 against 3.81 for the Sonus Faber Lumina II. The catch: Bass rolls off early for the cabinet size, measuring 77.6Hz at -3dB, 64.5Hz at -6dB, and 48.3Hz at -12dB; the preference score without a subwoofer is only 5.33.

The Sonus Faber Lumina II is the deeper-bass pick. Handmade Italian bookshelf speakers with leather-wrapped cabinets, competitive bass for their size and flexible placement. Its bass reaches about 60Hz before falling 3dB, against 77.6Hz for the Ascend Acoustics CMT-340 SE2. The catch: Not a neutral speaker: has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out.
