Short answer: the Polk T15, if you are buying new, though neither ranks well in its class. The Dynaudio X14 ranks higher than it (#63 vs #82 of 92 bookshelf speakers, 2.9/5 vs 1.9/5) but is discontinued, so only consider it used; the Polk T15 is still sold new at $149. Both are rated below 3.0/5 among the 92 bookshelf speakers; for better sound, the Philharmonic Ceramic Mini ranks #2 at $900.
Buy the Polk T15 if you want one new; the Dynaudio X14 is discontinued, so only look for it used.

The Two Speakers In Full
Dynaudio X14: $1,500 per pair Discontinued eBay
Pros: 1” silk-dome tweeter and 5.7” magnesium-silicate-polymer woofer in a compact two-way stand-mount, rated at 85dB sensitivity. Measured bass extension of 67.4Hz (-3dB), with a measured sensitivity of 82dB.
Cons: CEA2034 spinorama shows an uneven on-axis response from the lack of a waveguide to control tweeter beam width, plus a port resonance that boosts the lower midrange and imperfect crossover matching between the drivers. Too much energy in the lower and upper treble reads as bright, and directivity narrows at higher frequencies rather than staying controlled. The reviewer’s verdict: out of the box, the objective performance isn’t that great, though EQ can make it a satisfying speaker. Discontinued.

Polk T15: $149.00 per pair Amazon eBay
Pros: 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. Measured bass extension of 88.6Hz (-3dB), with a measured sensitivity of 89dB.
Cons: 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.”
