Short answer: the JBL 4349 if sound quality matters most, the JBL 4309 if price matters most. The JBL 4349 ranks #88 of 141 bookshelf speakers, rated 3.6/5, at $7,500. The JBL 4309 ranks #105, rated 3.3/5, at $2,200, $5,300 cheaper.
The JBL 4349 is the more accurate, deeper-bass pick. A high-output studio-monitor design with a large 12-inch woofer, compression driver and front-panel high-frequency controls. Its measured preference score, a predictor of how neutral it sounds, is 4.32 against 3.32 for the JBL 4309. Its bass reaches about 51.3Hz before falling 3dB, against 60.1Hz for the JBL 4309. Watch for: Large, heavy and costly, with response/directivity imperfections that keep measured preference below less expensive neutral monitors.
The case for the JBL 4309: A compact front-ported JBL monitor with an HDI horn, compression driver, 6.5-inch pulp woofer and adjustable UHF level. Watch for: Measured preference is modest for a roughly $2200 pair, and the four-ohm load needs solid amplification.
Buy the JBL 4349 if sound quality is the priority over the price, or the JBL 4309 if the price is the priority over sound quality.

JBL 4309: $2,200 per pair eBay
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 $2200 pair, and the four-ohm load needs solid amplification. The horn’s controlled dispersion provides less room-filling width than some conventional dome designs.
