Short answer: the Revel F328Be if sound quality matters most, the Q Acoustics 5040 if price matters most. The Revel F328Be ranks #9 of 188 floorstanding speakers, rated 4.7/5, at $19,359.90. The Q Acoustics 5040 ranks #97, rated 4.1/5, at $4,014.96, $15,344.94 cheaper.
Why pick the Q Acoustics 5040: C3 (Continuous Curved Cone) driver profile technology provides smooth midrange integration, controlled cone breakup, and improved bass damping. The tradeoff: 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.
The Revel F328Be is the more accurate pick. CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. Its measured preference score, a predictor of how neutral it sounds, is 6.40 against 3.80 for the Q Acoustics 5040. Watch for: Vertical directivity is asymmetric: the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis, reflecting the driver layout of this three-way tower.
Buy the Q Acoustics 5040 when the price outweighs sound quality for you, and the Revel F328Be when sound quality outweighs the price instead.

Q Acoustics 5040: $4,014.96 per pair Amazon eBay
Same family: the Q Acoustics 5010 (smaller bookshelf, estimated 3.5/5), the Q Acoustics 5020 (larger bookshelf, rated 2.2/5), the Q Acoustics 5050 (larger floorstanding, ranked higher, estimated 4.3/5) and the Q Acoustics 5090 (center, estimated 3.7/5).
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.

Revel F328Be: $19,359.90 per pair Crutchfield eBay
Same family: the Revel M126Be (bookshelf, rated 4.3/5), the Revel F226Be (smaller floorstanding, ranked lower, rated 4.6/5), the Revel F228Be (smaller floorstanding, ranked lower, rated 4.5/5) and the Revel C426Be (center, rated 4/5).
Pros: CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. Predicted in-room response is extremely accurate, with a smooth ~5dB downward slope from bass to treble that suits typical rooms without correction. Early reflections sum very nicely with the direct sound. Horizontal beamwidth of about ±70 degrees is wide and quite smooth. At 96dB SPL/1m distortion stays easily below the reviewer’s audibility threshold across nearly the whole range. Measured bass extension of 74Hz (-3dB), with a measured sensitivity of 91dB.
Cons: Vertical directivity is asymmetric: the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis, reflecting the driver layout of this three-way tower. Impedance dips to a minimum of 3 ohms with an additional resonance-driven phase swing, calling for an amplifier comfortable with a demanding load. Very expensive and very heavy (51 kg each).
