Sonus Faber Sonetto II G2 vs Ascend Acoustics CMT-340 SE2

The Sonus Faber Sonetto II G2 is the deeper-bass choice. An Italian bookshelf speaker with a silk dome tweeter, a stylish concrete and metal base and evenly behaved dispersion. Its bass reaches about 62Hz before falling 3dB, against 77.6Hz for the Ascend Acoustics CMT-340 SE2. The catch: Sounds notably bright pointed directly on-axis; toeing the speaker out about 30° reduces treble energy and sibilance meaningfully.

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 4.25 for the Sonus Faber Sonetto II G2. 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.
