Short answer: the Polk T50, if you are buying new. The JBL 4367 ranks higher than it (#16 vs #126 of 188 floorstanding speakers, 4.6/5 vs 3.8/5) but is discontinued, so only consider it used; the Polk T50 is still sold new at $498. The JBL 4367’s replacement, the JBL 4369, is rated 4.7/5.
Why pick the Polk T50: Pretty deep bass for the price. The tradeoff: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up.
The JBL 4367 is the more accurate option. 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 4.14 for the Polk T50. Watch for: At roughly $16500/pair, this is a major investment: the reviewer recommends buying from a dealer with a liberal return policy.
Buy the Polk T50 new; the JBL 4367 is no longer sold new, so it only makes sense as a used find.

Same family: the Polk T15 (bookshelf, rated 1.9/5).
Pros: Pretty deep bass for the price. Distortion at 86dB SPL/1m is reasonably controlled outside a narrow spike around 250Hz. The reviewer notes performance is “not too bad for a budget speaker” once the two main tonal issues are addressed with EQ. Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 86.3dB.
Cons: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up. Just okay vertical off axis. Impedance and phase show several resonances between 200Hz-1kHz, with a minimum impedance of 4.2 ohms. Distortion rises substantially at 96dB SPL/1m across the midrange, with repeated peaks between 100Hz-2kHz.

JBL 4367: $16,500 per pair Discontinued eBay
Newer model: the JBL 4369, ranked higher, estimated 4.7/5.
Same family: the JBL 4309 (smallest bookshelf, rated 3.3/5), the JBL 4312G (bookshelf, estimated 3.9/5), the JBL 4349 (largest bookshelf, rated 3.6/5) and the JBL 4369 (larger floorstanding, 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.
