Short answer: the Revel F228Be for better sound quality, the Infinity Primus 360 for the lower price. The Revel F228Be ranks #16 of 71 floorstanding speakers at $7000. The Infinity Primus 360 ranks #40 at $650, $6350 cheaper.
What the Revel F228Be offers: 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. Watch for: 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).
What the Infinity Primus 360 offers: A three-way tower from 2005 (two 6.5” mid-woofers, a 4” mid-range, and a 0.75” dome tweeter, 8 ohms nominal) that holds up remarkably well by modern measurement standards: on-axis linearity is within about ±2dB, and the listening window stays consistent out to roughly ±30° horizontal and ±10° vertical off the mid-range axis. Horizontal directivity is well controlled out to about ±75° before tonality starts to drift, meaning the reflected sound in a room stays close in character to the direct sound - a speaker that takes EQ well without fighting itself. Harmonic distortion measures low at both 86dB and 96dB, and multitone distortion stays under the reviewer’s 3% threshold. Silky, smooth midrange with a rich lower-midrange/upper-bass character. No mechanical issues or surround degradation found in a 20-year-old pair, and a second unit measured within about 1-1.5dB of the first, suggesting good long-term consistency for the design. Watch for: Manufacturer-spec sensitivity of 93dB runs about 3-4dB optimistic versus the measured 89.4dB average. Bass output drops off fairly quickly below about 50Hz in-room (F3 53Hz, F10 37Hz), so a subwoofer is needed for real low-end extension. Resonances show up around 170Hz, 220Hz, and 350Hz. On-axis, the lower treble can sound a bit bright or sibilant when the speaker is aimed directly at the listener; toeing out about 10-15° (rather than the more extreme 30°) gave the best balance, and some sidewall acoustic absorption further tamed a 4-5kHz peak. Placed close to the rear wall, bass gets boomy - pulling the speakers out about a foot resolves most of it, with roughly 1.5 feet from the wall as a good compromise between bass character and typical room aesthetics. Straying beyond about 25° above or below the mid-range axis introduces audible suckout. No longer in production, so it’s a used/secondhand purchase only.
Buy the Revel F228Be if sound quality matters more than the price. Buy the Infinity Primus 360 if the price matters more than sound quality.
