Short answer: the Paradigm Monitor SE Atom for placement flexibility, the Polk Audio XT15 for price and compatibility. The Atom’s consistent on-axis, listening-window, and off-axis directivity makes it less room-dependent, but its on-axis response dips through 2-4kHz and resonates around 15kHz without EQ. The XT15 is Hi-Res Audio Certified and works on 4- or 8-ohm outputs, though its bass rolls off at 77.6Hz (-3dB) and 54.2Hz (-10dB).
Buy the Polk Audio XT15. It is rated higher for sound quality than the Paradigm Monitor SE Atom and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
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.

Paradigm Monitor SE Atom: $399.98 per pair Paradigm eBay
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. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 85dB.
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.
