Short answer: the Ascend Acoustics CMT-340 SE2. It ranks #24 of 222 bookshelf speakers by sound quality, rated 4.4/5, at $798. The Triangle Borea BR03 ranks #198, rated 2.8/5, at $399, $399 cheaper, which does not close the gap in sound quality.
The Triangle Borea BR03 is the deeper-bass choice. A budget French bookshelf speaker with dual front ports, decent bass for the price and solid, well braced build quality. Its bass reaches about 57Hz before falling 3dB, against 77.6Hz for the Ascend Acoustics CMT-340 SE2. The tradeoff: A noticeable mid-range suckout, most pronounced in the upper mid-range/lower treble, that the reviewer attributes to cabinet resonances and driver breakup rather than a deliberate voicing choice: it makes vocals and instruments sound recessed and thin rather than warm.
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 4.03 for the Triangle Borea BR03. 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.
Buy the Ascend Acoustics CMT-340 SE2. It is rated higher for sound quality, and saving $399 with the Triangle Borea BR03 does not make up for the sound-quality gap.
