Short answer: the Klipsch RP-500M II for better sound quality, the Paradigm Monitor SE Atom for the lower price. The Klipsch RP-500M II ranks #10 of 56 bookshelf speakers at $389.99. The Paradigm Monitor SE Atom ranks #26 at $318, $71.99 cheaper.
The case for the Klipsch RP-500M II: Major mid-range clarity improvement over the original RP-500M: about a 5dB fill-in between 1-3kHz in the estimated in-room response, giving a noticeably more resolved, detailed midrange. The tradeoff: Klipsch’s quoted sensitivity (around 92-93dB) uses an unconventional in-room-based rating rather than the standard anechoic measurement; on an anechoic basis it measures closer to about 85dB.
On the Paradigm Monitor SE Atom side: 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. Set against that: 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.
Buy the Klipsch RP-500M II if sound quality matters more than the price. Buy the Paradigm Monitor SE Atom if the price matters more than sound quality.

The Two Speakers In Full
Klipsch RP-500M II: $389.99 Amazon
Pros: Major mid-range clarity improvement over the original RP-500M: about a 5dB fill-in between 1-3kHz in the estimated in-room response, giving a noticeably more resolved, detailed midrange. More neutral and linear overall than its sibling RP-600M II, which carries about 2-3dB more high-frequency energy and a touch more bass but less overall balance. Very precise soundstage imaging and instrument placement. Distortion through the midrange is cleaner than the previous generation.
Cons: Klipsch’s quoted sensitivity (around 92-93dB) uses an unconventional in-room-based rating rather than the standard anechoic measurement; on an anechoic basis it measures closer to about 85dB, in line with typical bookshelf speakers this size, so it isn’t the outlier in efficiency the spec sheet implies. Horizontal dispersion of about ±40-50° is narrower and more directive than the reviewer’s preference for a wider, more enveloping soundstage. Toeing the speaker out to widen the soundstage or soften on-axis brightness comes at some cost to imaging precision. Slightly less clean in the tweeter region than the midrange, likely tied to crossover placement, though not considered a dealbreaker. Low-frequency output is limited - measured around 95dB at 4 meters for the pair before the woofers started to unload, so a subwoofer is recommended for anyone wanting real bass rather than stepping up to a larger model.

Paradigm Monitor SE Atom: $318 Amazon
Pros: 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.
Cons: 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.
