Short answer: the Buchardt Audio E50 if sound quality matters most, the Ascend Acoustics CMT-340 SE2 if price matters most. The Buchardt Audio E50 ranks #16 of 222 bookshelf speakers, rated 4.5/5, at $4,600. The Ascend Acoustics CMT-340 SE2 ranks #24, rated 4.4/5, at $798, $3,802 cheaper.
The Buchardt Audio E50 is the more accurate, deeper-bass pick. A bookshelf speaker with remarkably deep bass for its size, a very neutral midrange, and low distortion, with no need to sit near a wall. Its measured preference score, a predictor of how neutral it sounds, is 5.84 against 5.33 for the Ascend Acoustics CMT-340 SE2. Its bass reaches about 40Hz before falling 3dB, against 77.6Hz for the Ascend Acoustics CMT-340 SE2. The tradeoff: A roughly 3dB dip in the upper midrange/lower treble softens attack and dialogue clarity: the reviewer’s main complaint, and it’s baked into the crossover rather than a directivity artifact, so it’s audible both on and off axis.
The case for the Ascend Acoustics CMT-340 SE2: 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. The tradeoff: 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.
