Short answer: the Paradigm Monitor SE Atom for better sound quality, the Definitive Technology ProMonitor 1000 for the lower price. The Paradigm Monitor SE Atom ranks #49 of 87 bookshelf speakers at $318. The Definitive Technology ProMonitor 1000 ranks #79 at $249, $69 cheaper.
What the Definitive Technology ProMonitor 1000 offers: 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. Watch for: 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 $500/pair ProMonitor 1000 “a bad experiment that should be forgotten” and concluding “there is nothing Pro about it.”
What the Paradigm Monitor SE Atom offers: Good, consistent directivity across the on-axis, listening-window, and off-axis curves makes the Atom easier to equalize and less room-dependent than many budget speakers. Bass tuning is well judged, letting the woofer play loud on demanding tracks without bottoming out even without a subwoofer. Paradigm’s NRC research pedigree shows in the horizontal and vertical dispersion measurements. Watch for: On-axis response is uneven out of the box, with a 2-4kHz dip followed by a peak and a resonance around 15kHz that the reviewer said gives it a bright, “showroom” voicing without EQ correction. There’s no meaningful bass extension for full-range use, so a subwoofer is effectively required for anything beyond desktop or near-field listening.
Buy the Definitive Technology ProMonitor 1000 if the price matters more than sound quality. Buy the Paradigm Monitor SE Atom if sound quality matters more than the price.
If sound quality matters at all to you, skip the Definitive Technology ProMonitor 1000. It ranks near the bottom of the 87 bookshelf speakers, so look higher up the list instead.
