These are not really the same size class, and that is the honest framing here. The JBL 4367 ranks #15 of 89 floorstanding speakers by sound quality at $16,500; the JBL 4309 ranks #105 of 141 bookshelf speakers by sound quality at $2,200.
The JBL 4367 is the more accurate, deeper-bass choice. Three-way design pairing a 15” front-ported woofer with a compression driver on a controlled-dispersion horn/waveguide, crossed over at 700Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.07 against 3.32 for the JBL 4309. Its bass reaches about 43Hz before falling 3dB, against 60.1Hz for the JBL 4309. The catch: At roughly $16500/pair, this is a major investment: the reviewer recommends buying from a dealer with a liberal return policy.
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. The tradeoff: Measured preference is modest for a roughly $2200 pair, and the four-ohm load needs solid amplification.
One note: the JBL 4367 is discontinued, but it still ranks #15 of 89 floorstanding speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the JBL 4367 at $16,500 if you want a floorstanding speaker. Buy the JBL 4309 at $2,200 if you want a bookshelf speaker instead.

The Two Speakers In Full
JBL 4367: $16,500 per pair Discontinued eBay
Newer model: the JBL 4369, ranked higher, estimated 4.7/5.
Pros: Three-way design pairing a 15” front-ported woofer with a compression driver on a controlled-dispersion horn/waveguide, crossed over at 700Hz. On-axis frequency response is nearly dead flat, holding within about ±1.5dB, with the listening window tracking it closely except right at the crossover. Distortion stays below 1% THD across the entire audible band at both 86dB and 96dB. Compression/dynamic-range linearity is exceptional: within about a quarter of a dB from 76dB to 102dB, among the best the reviewer has measured. High sensitivity (about 92.6dB average) eases the amplifier match despite the speaker’s size. Minimal rear radiation thanks to the 15” woofer’s directivity and front-firing ports: rear energy runs about 20dB down from the primary wavefront, giving it a near-cardioid radiation pattern. Well-controlled horn directivity keeps the soundstage from noticeably shifting in width across the 700Hz crossover region. A natural high-frequency rolloff above about 7-8kHz gives it an easy, non-fatiguing character for extended listening sessions. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 92.5dB.
Cons: At roughly $16500/pair, this is a major investment: the reviewer recommends buying from a dealer with a liberal return policy. Vertical response shows dips beyond about ±10-20°, with a larger null further out: an inherent trade-off of mating a 15” woofer to a horn compression driver at a 700Hz crossover, since crossing lower would hurt power handling and dynamic range. Horizontal directivity isn’t perfectly consistent with frequency: narrow (about ±20°) through 200-800Hz, briefly widening to near ±50° above the crossover, then narrowing again at high frequency. An unusual, non-constant pattern. The high-frequency rolloff that gives it an easy-listening character also reduces the sense of air and space in the soundstage when listening from off-center seats. Massive and heavy (about 120 lbs, roughly 36-37” tall): needs to be raised on a stand to bring the horn to ear level, and isn’t something one person easily moves alone. Only modest EQ adjustment is available on the speaker itself (about ±1-2dB bass/treble trim). Discontinued.

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.
