Short answer: the Klipsch RP-600M II. It ranks #123 of 222 bookshelf speakers by sound quality, rated 3.7/5, at $449.99; the JBL 4349 ranks #140, rated 3.6/5, and costs $7,500, so there is little reason to consider the other one.
The Klipsch RP-600M II is the more accurate pick. Bookshelf speakers with a large horn tweeter, wide soundstage, high efficiency and bi-amp ready terminals. Its measured preference score, a predictor of how neutral it sounds, is 5.64 against 4.32 for the JBL 4349. The tradeoff: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced.
The JBL 4349 is the deeper-bass option. A big high-output studio monitor with a 12 inch woofer, compression driver, deep bass and front-panel treble controls. Its bass reaches about 51.3Hz before falling 3dB, against 70Hz for the Klipsch RP-600M II. The catch: Large, heavy and costly, with response/directivity imperfections that keep measured preference below less expensive neutral monitors.
Buy the Klipsch RP-600M II. It is rated higher for sound quality than the JBL 4349 and costs less, so only choose the other one for a particular feature it does better.
