Short answer: the Sony SS-CS5 M2, if you are buying new. The Revel M105 ranks higher than it (#13 vs #49 of 90 bookshelf speakers, 4.2/5 vs 3.2/5) but is discontinued, so only consider it used; the Sony SS-CS5 M2 is still sold new at $278.
Buy the Sony SS-CS5 M2 new; the Revel M105 is no longer sold new, so it only makes sense as a used find.

Revel M105: $1,500 per pair Discontinued eBay
Pros: CEA2034 spinorama shows an essentially flat on-axis response with only a small 5kHz peak, a smooth listening window, and clean waterfall decay. Wide horizontal dispersion gives flexibility with toe-in. The reviewer called it reference-quality performance with minor EQ correction applied. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 85dB.
Cons: Low nominal impedance demands a capable amplifier that can handle low-impedance loads. Bass distortion runs high in the 80-250Hz range from woofer displacement, and maximum output is limited compared to larger designs. Discontinued.

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.
