Short answer: the Radiant Acoustics Clarity 66, if you are buying new. The JBL 4367 measures as well as it (#16 vs #11 of 228 floorstanding speakers, 4.6/5 vs 4.6/5) but is discontinued, so only consider it used; the Radiant Acoustics Clarity 66 is still sold new at $7,998. The JBL 4367’s replacement, the JBL 4369, is rated 4.7/5 at $25,000.
The Radiant Acoustics Clarity 66 is the more accurate, deeper-bass pick. 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 5.07 for the JBL 4367. Its bass reaches about 32.2Hz before falling 3dB, against 43Hz for the JBL 4367. The catch: Vertical directivity is narrow and horizontal coverage is uneven, so listening height and placement affect tonal balance.
What the JBL 4367 does well: A studio monitor style floorstander with a 15 inch woofer and horn, flat sound, huge dynamics and easy to drive. Watch for: At roughly $16500/pair, this is a major investment: the reviewer recommends buying from a dealer with a liberal return policy.
Buy the Radiant Acoustics Clarity 66, since the JBL 4367 is discontinued and only worth hunting down used.
