Short answer: the Revel F228Be, the less placement-sensitive tower. The Q Acoustics 5040 uses C3 driver profile technology for smooth midrange integration and controlled cone breakup, but a mid-bass scoop around 200Hz produces an F3 of 70Hz and forces boundary placement 11-22 inches from the front wall. The F228Be is essentially flat on-axis with very nice directivity, though it dips to 3.4 ohms.

Older model: the Revel F208 (ranked higher, rated 4.5/5).
Pros: CEA2034 spinorama shows an essentially flat on-axis response with very nice directivity. Predicted in-room response is nearly perfect, with a smooth slope down from bass to treble. Horizontal beamwidth of about ±70 degrees is wide and holds up well until narrowing above 8kHz. Vertical directivity offers more degrees of listening-height freedom than a typical bookshelf design, a benefit of this tower’s driver layout. Distortion is extremely low across the full audio range at 86dB SPL/1m and stays comfortable even at 96dB SPL/1m. Near-field measurements of the individual drivers show nice, well-integrated crossover behavior with only low-level resonances. Measured bass extension of 61Hz (-3dB), with a measured sensitivity of 89.3dB.
Cons: Minimum impedance dips to 3.4 ohms with a secondary rise around 2kHz, calling for an amplifier comfortable with a demanding load. Very expensive and very heavy (51 kg each).

Q Acoustics 5040: $2,472.98 per pair Amazon eBay
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.
