Short answer: the Definitive Technology ProMonitor 1000 handles hard use better; the Dynaudio X14 is the more conventional two-way, though neither ranks well in its class. The ProMonitor’s bass distortion is well controlled, but its CEA2034 spinorama shows severely reduced bass energy between 40-120Hz and a severe resonance around 14kHz. The X14 pairs a 1” silk-dome tweeter with a 5.7” woofer rated at 85dB sensitivity. They are $1,002 apart. Both are rated below 3.0/5 among the 92 bookshelf speakers, so if sound quality matters, consider the Philharmonic Ceramic Mini instead, ranked #2 at $900.
Buy the Definitive Technology ProMonitor 1000 new; the Dynaudio X14 is no longer sold new, so it only makes sense as a used find.

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.

Definitive Technology ProMonitor 1000: $498 per pair Amazon eBay
Pros: Bass distortion is well controlled per the measurements, and the slow bass rolloff means it can be pushed fairly hard for its size. Ships with a footer that keeps the small cabinet planted despite its light weight. Measured bass extension of 95Hz (-3dB), with a measured sensitivity of 86dB.
Cons: CEA2034 spinorama shows severely reduced bass energy between 40-120Hz, a directivity mismatch between the tweeter and woofer, and a severe resonance/interference issue around 14kHz. Distortion at 96dB SPL was so bad the reviewer limited testing to 86dB. Direct comparison to a $118/pair Pioneer SP-BS22-LR left the reviewer calling the $249/pair ProMonitor 1000 “a bad experiment that should be forgotten” and concluding “there is nothing Pro about it.”
