KEF Q3 Meta vs Ascend Acoustics CMT-340 SE2

The KEF Q3 Meta is the deeper-bass pick. Coaxial bookshelf speakers with very wide dispersion, punchy kick drums and bass tuning that works close to a wall. Its bass reaches about 52Hz before falling 3dB, against 77.6Hz for the Ascend Acoustics CMT-340 SE2. The tradeoff: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application.

The Ascend Acoustics CMT-340 SE2 is the more accurate choice. 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 4.66 for the KEF Q3 Meta. 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.
