Short answer: the Radiant Acoustics Clarity 66 if sound quality matters most, the JBL Stage 2 280F if price matters most. The Radiant Acoustics Clarity 66 ranks #11 of 228 floorstanding speakers, rated 4.6/5, at $7,998. The JBL Stage 2 280F ranks #188, rated 3.4/5, at $1,059.90, $6,938.10 cheaper.
The Radiant Acoustics Clarity 66 is the more accurate, deeper-bass choice. Highly accurate floorstanding speakers with Purifi woofers and bass deep enough to skip a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 6.01 against 4.69 for the JBL Stage 2 280F. Its bass reaches about 32.2Hz before falling 3dB, against 48Hz for the JBL Stage 2 280F. The tradeoff: Vertical directivity is narrow and horizontal coverage is uneven, so listening height and placement affect tonal balance.
What the JBL Stage 2 280F does well: An easy to drive tower with twin 8 inch woofers that plays loud with low distortion for the price. The catch: Explicitly called out as disappointing relative to expectations for the JBL name and this price point: lacks native linearity compared to similarly-priced alternatives like the Polk Reserve R500, which the reviewer recommends instead for anyone who doesn’t want to rely on EQ.
Buy the Radiant Acoustics Clarity 66 when sound quality outweighs the price for you, and the JBL Stage 2 280F when the price outweighs sound quality instead.
