Short answer: the Philharmonic Ceramic Mini on measured sound quality, the Ascend Acoustics HTM-200SE2 on price. The Philharmonic Ceramic Mini ranks #2 of 87 bookshelf speakers at $900. The Ascend Acoustics HTM-200SE2 ranks #7 at $368, $532 cheaper.
What the Ascend Acoustics HTM-200SE2 offers: High-quality manufacturer NFS data shows 0.385dB on-axis average absolute deviation, 0.428 listening-window smoothness, and unusually even 80-degree dispersion in both planes. The compact sealed cabinet is easy to place, while the preference score reaches 7.11 with a subwoofer. Watch for: Limited bass is the main tradeoff, measuring 87.9Hz at -3dB, 71.8Hz at -6dB, and 51.3Hz at -12dB; its preference score falls to 4.20 without a subwoofer. The 3.62 sound-power directivity-index standard deviation is respectable rather than exceptional, and the small woofers limit deep-bass output.
What the Philharmonic Ceramic Mini offers: Gorgeous looks and finish options for the price. Very low midrange distortion for the size, well under 1% above about 400-500Hz. Excellent on-axis linearity. Mild, pleasant bass bump around 100Hz that adds welcome warmth without being excessive. Wide soundstage and dispersion (~70-80 degrees horizontally). Clean cabinet and port with no measured resonances. A great value combination of looks and performance at this price. Watch for: Somewhat limited output capability for its size - audible woofer compression (“flopping”) around 95dB at 3 meters for a stereo pair, so keep to moderate levels or pair with a subwoofer for home theater use. A mild diffraction-related dip around 4-6kHz can cause occasional sibilance on some vocal tracks. Measured sensitivity (82.2dB average) runs a bit below the manufacturer’s claimed 84dB, so it needs more amp power than the spec alone suggests. Needs a subwoofer for real bass authority below about 40Hz.
