Short answer: the JBL 4349. It ranks #124 of 188 bookshelf speakers by sound quality (rated 3.6/5) at $7,500 and is still sold new; the JBL 4429 ranks #145 (rated 3.4/5) and is discontinued, so it is only an option used.
Why pick the JBL 4349: A high-output studio-monitor design with a large 12-inch woofer, compression driver and front-panel high-frequency controls. The tradeoff: Large, heavy and costly, with response/directivity imperfections that keep measured preference below less expensive neutral monitors.
The JBL 4429 is the deeper-bass choice. A large studio monitor with a 12” pure pulp woofer and 2” and 0.75” titanium compression drivers on a SonoGlass horn, with front panel level controls. Its bass reaches about 45.2Hz before falling 3dB, against 51.3Hz for the JBL 4349. Watch for: JBL no longer sells it new.
