Short answer: the Radiant Acoustics Clarity 66. It ranks #11 of 228 floorstanding speakers by sound quality, rated 4.6/5, at $7,998; the Revel F228Be ranks #29, rated 4.5/5, and costs $11,000, so there is not much of a tradeoff to weigh.
The Radiant Acoustics Clarity 66 is the deeper-bass choice. Highly accurate floorstanding speakers with Purifi woofers and bass deep enough to skip a subwoofer. Its bass reaches about 32.2Hz before falling 3dB, against 61Hz for the Revel F228Be. The tradeoff: Vertical directivity is narrow and horizontal coverage is uneven, so listening height and placement affect tonal balance.
The case for the Revel F228Be: Premium floorstanding speakers with extremely accurate sound, very low distortion, wide even dispersion and a forgiving range of listening heights. The tradeoff: Minimum impedance dips to 3.4 ohms with a secondary rise around 2kHz, calling for an amplifier comfortable with a demanding load.
Buy the Radiant Acoustics Clarity 66. It is rated higher for sound quality than the Revel F228Be and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
