Short answer: the Polk Audio XT15 for easy amplification, the Dynaudio X14 for a compact stand-mount with real driver pedigree. The X14 pairs a 1” silk-dome tweeter with a 5.7” magnesium-silicate-polymer woofer and is rated at 85dB sensitivity, but without a waveguide its on-axis response is uneven and a port resonance boosts the lower midrange. The XT15’s own roll-off at 77.6Hz (-3dB) and 54.2Hz (-10dB) means neither is a bass-first choice.
Buy the Polk Audio XT15. It is rated higher for sound quality and still sold new, while the Dynaudio X14 is discontinued.

Polk Audio XT15: $179.00 per pair Amazon B&H Photo Video Crutchfield eBay
Pros: Very low $179/pair entry price for a Hi-Res Audio Certified 2-way design that’s Dolby Atmos and DTS:X compatible, and works with either 4- or 8-ohm amplifier outputs so it drops into almost any AVR without matching concerns. Off axis sound tracks the on axis response reasonably consistently for the price. Measured bass extension of 77.6Hz (-3dB).
Cons: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB). On-axis response is relatively uneven, with an average deviation of about 0.45dB, and its listening window is less smooth than pricier speakers. Modest 86dB sensitivity wants a reasonably powered amp channel. The 5.25” bi-laminate paper woofer is Polk’s entry-tier driver, not the polypropylene/Turbine cones used in its pricier Signature Elite/Reserve lines.

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.
