Short answer: the Revel F328Be on measured sound quality, the Radiant Acoustics Clarity 66 on price. The Revel F328Be ranks #9 of 228 floorstanding speakers, rated 4.7/5, at $19,359.90. The Radiant Acoustics Clarity 66 ranks #11, rated 4.6/5, at $7,998, $11,361.90 cheaper.
The Radiant Acoustics Clarity 66 is the deeper-bass option. 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 74Hz for the Revel F328Be. Watch for: Vertical directivity is narrow and horizontal coverage is uneven, so listening height and placement affect tonal balance.
Why pick the Revel F328Be: Extremely accurate floorstanding speakers, with a beryllium tweeter, wide even coverage and very low distortion at loud volume. The catch: 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 Radiant Acoustics Clarity 66 if the price is the priority over sound quality, or the Revel F328Be if sound quality is the priority over the price.
