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 Revel M126Be ranks #38, rated 4.3/5, and costs $4,400, which makes this an easy call rather than a real tradeoff.
The Ascend Acoustics CMT-340 SE2 is the deeper-bass option. 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 bass reaches about 77.6Hz before falling 3dB, against 103Hz for the Revel M126Be. Watch for: 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.
What the Revel M126Be does well: A beryllium tweeter bookshelf speaker with wide, immersive imaging and a smooth, even low end that avoids boominess. The tradeoff: At $2200/pair, the reviewer doesn’t consider it a strong value: an improvement over the less expensive Revel M106 and other Performa3 models, but not proportional to the price jump.
Buy the Ascend Acoustics CMT-340 SE2. It is rated higher for sound quality than the Revel M126Be and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
