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.

Klipsch RP-500M II: $389.99 per pair Amazon eBay
Older model: the Klipsch RP-500M (ranked lower, rated 3.4/5).
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. Measured bass extension of 67Hz (-3dB), with a measured sensitivity of 85dB.
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.
