#161 JBL 4309: $1,299.99 per pair Safe and Sound HQ eBay

Same family: the JBL 4312G (larger bookshelf, ranked higher, estimated 3.9/5), the JBL 4349 (larger bookshelf, ranked higher, rated 3.6/5), the JBL 4367 (smaller floorstanding, rated 4.6/5) and the JBL 4369 (larger floorstanding, estimated 4.7/5). See every JBL 4300 Series generation.

Pros: A compact front-ported JBL monitor with an HDI horn, compression driver, 6.5-inch pulp woofer and adjustable UHF level. The local snapshot records 42Hz extension, a 3.32 raw score and 5.33 with a subwoofer. Measured bass extension of 60.1Hz (-3dB).

Cons: Measured preference is modest for a roughly $1300 pair, and the four-ohm load needs solid amplification. The horn’s controlled dispersion provides less room-filling width than some conventional dome designs.
