Short answer: the Radiant Acoustics Clarity 66 on measured sound quality, the Klipsch RP-6000F II on price. The Radiant Acoustics Clarity 66 ranks #11 of 228 floorstanding speakers, rated 4.6/5, at $7,998. The Klipsch RP-6000F II ranks #140, rated 3.9/5, at $999.98, $6,998.02 cheaper.
The case for the Klipsch RP-6000F II: An affordable horn tower that handles lots of power cleanly, with precise imaging for home theater. Watch for: Worse baffle-step coloration than the smaller Klipsch RP-5000F II (3-4dB swing vs 2dB), plus a sibilance issue the 5000F doesn’t have: a real regression in tonal balance despite the higher price.
The Radiant Acoustics Clarity 66 is the better-sounding, 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 67Hz for the Klipsch RP-6000F II. The tradeoff: Vertical directivity is narrow and horizontal coverage is uneven, so listening height and placement affect tonal balance.
Buy the Klipsch RP-6000F II if the price is the priority over sound quality, or the Radiant Acoustics Clarity 66 if sound quality is the priority over the price.
