Short answer: the Philharmonic Ceramic Mini if sound quality matters most, the Polk T15 if price matters most. The Philharmonic Ceramic Mini ranks #2 of 87 bookshelf speakers at $900. The Polk T15 ranks #78 at $149, $751 cheaper.
What the Polk T15 offers: Extremely affordable 2-way design that actually measured better at +/-20 degrees vertical off-axis than directly on-axis. In near-field desktop use, the reviewer found the T15 “didn’t sound that horrible,” partly because nearby desk reflections mask the frequency response dip. Watch for: Spinorama analysis reveals what Amir called a “horrific drop in upper mids/lower treble region of 3 to 6 kHz,” likely from tweeter-woofer phase cancellation directly on-axis. Measured impedance ranges from 4-8 ohms, contradicting the specified 6-8 ohm range, and there’s a distortion peak around 400Hz. On- and off-axis response “vary a ton,” making listening position unusually important. The reviewer recommends saving up for the Pioneer SP-BS22-LR instead: “I can’t justify recommending the Polk T15 even though subjective performance was not horrible.”
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.
Buy the Polk T15 when the price outweighs sound quality for you, and the Philharmonic Ceramic Mini when sound quality outweighs the price instead.
The Polk T15 is not a sound-quality pick. It sits near the bottom of the 87 bookshelf speakers; there are better options higher up.
