Short answer: the Sony SS-CS5 M2, or the Paradigm Monitor SE Atom if you will use EQ. The Atom’s consistent directivity across on-axis, listening-window and off-axis makes it easier to equalize and less room-dependent, but its uneven on-axis response has a 2-4kHz dip, a peak and a resonance near 15kHz. The Sony’s bracing and updated crossover give a smoother, more neutral sound at $278 against $399.98, with mild 3-5kHz sibilance.
Buy the Sony SS-CS5 M2. Both are rated the same for sound quality, and it costs $121.98 less than the Paradigm Monitor SE Atom.

Sony SS-CS5 M2: $278.00 per pair Amazon eBay
Pros: Added internal bracing (corners, sides, front baffle) plus an updated crossover meaningfully reduce the resonance issues that plagued the original SS-CS5, giving a smoother, more neutral character overall. A modest mid-range dip (about 1-2dB) is present but tolerable, and the reviewer would rather have this dip than a peak in that region. Slightly deeper bass than the previous version, measuring about 2dB more output around 60Hz. Distortion drops noticeably when crossed to a subwoofer around 80-120Hz, meaningfully improving midrange clarity and detail versus running full-range. Easy to drive on a standard AVR: no need for a dedicated high-power amplifier. More modern, understated waveguide look compared to the previous version’s glossy trim. Measured bass extension of 80Hz (-3dB).
Cons: Mild sibilance in the 3-5kHz range stands out on S and T sounds in vocals. Some forwardness in the midrange noticeable on certain vocal recordings. Soundstage and sense of envelopment are comparatively flat and two-dimensional, especially next to reference-quality speakers with strong 3D imaging. Marketed as a “three-way” design mainly due to an added super-tweeter that the reviewer considers largely superfluous: it engages only at very high frequencies and adds complexity without a clearly audible benefit, when that cost might have been better spent on the main crossover. Output-limited: realistic ceiling is around the mid-90s dB SPL at a few meters, with comfortable listening closer to 75-85dB at 3-4 meters before distortion and compression become audible. Bass noticeably compresses/shelves below about 120Hz as volume increases, softening kick-drum impact at higher output. Smaller drivers and a lighter motor structure than rivals like the Polk XT20, which the reviewer generally prefers for its better directivity and higher SPL capability. Still needs a subwoofer for any real bass extension.

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.
