Short answer: the Q Acoustics 5040, if you are buying new. The Revel F208 ranks higher than it (#16 vs #41 of 74 floorstanding speakers, 4.5/5 vs 4.1/5) but is discontinued, so only consider it used; the Q Acoustics 5040 is still sold new at $2,472.98.
Buy the Q Acoustics 5040, since the Revel F208 is discontinued and only worth hunting down used.

Newer model: the Revel F228Be, ranked lower, rated 4.5/5.
Pros: CEA2034 spinorama shows a fairly even on-axis response with sensitivity matching spec at ~87-88dB. Predicted in-room response is a smooth, textbook-quality downward slope that should translate well to most rooms without correction. Early reflections sum so cleanly with the direct sound that side-wall absorption isn’t recommended: it would work against the speaker’s naturally well-integrated off-axis behavior. Distortion stays below 0.5% from 100Hz up at 96dB/1m, with all distortion components falling below audible threshold above 200Hz. Very wide horizontal directivity of about ±75 degrees. Measured performance was judged very close to Revel’s own flagship Salon2, and Revel’s speakers (including this one) are developed using Harman’s double-blind listening test methodology. Preference score of 7.4 (7.7 with a subwoofer added). Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 88.2dB.
Cons: Some directivity error and tweeter-response ripple right at the 2.2kHz crossover point. A notable on-axis dip at about 4kHz, attributed to probable cabinet diffraction. Cumulative spectral decay (waterfall) shows an unexplained resonance around 4-5kHz that the reviewer couldn’t pin down a clear cause for. Vertical directivity shows narrowband interference nulls just above and below the tweeter axis (roughly 2-3kHz), typical of a non-coaxial tower with vertically separated drivers, so listening height matters more than it would with a coincident design. Minimum impedance dips to 3.4 ohms, calling for a robust, high-current amplifier. Distortion climbs substantially below about 80-100Hz (up to ~5% in the deep bass) when driven hard, an excursion-limited trade-off typical of towers at high output. Isolating the woofers alone shows their usable range ending around 500-700Hz at the crossover, with somewhat elevated (though still low in absolute terms) 2nd/3rd harmonic distortion in the 100-300Hz region. Discontinued.

Pros: C3 (Continuous Curved Cone) driver profile technology provides smooth midrange integration, controlled cone breakup, and improved bass damping. High voltage sensitivity (91.5dB SPL at 2.83V/1m) allows loud listening with low-to-moderate amplifier wattage. Cabinet features Point-to-Point (P2P) internal bracing and Helmholtz Pressure Equalizer (HPE) tubes to suppress internal standing waves and panel vibrations. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 91.5dB.
Cons: Free-field frequency response exhibits a noticeable mid-bass scoop around 200Hz (~6dB lower than mean SPL), causing an F3 of 70Hz (F10 of 39Hz) in open space and requiring boundary placement (11-22 inches from front wall) to reinforce upper bass output. Measurements indicate an enclosure resonance near 300Hz visible in sound power data. Minimum impedance drops to 3.0 ohms, demanding a stable 4-ohm rated amplifier despite high sensitivity.
