Short answer: the Klipsch Heresy IV, if you are buying new. The JBL 4367 ranks higher than it (#16 vs #184 of 188 floorstanding speakers, 4.6/5 vs 2.3/5) but is discontinued, so only consider it used; the Klipsch Heresy IV is still sold new at $3,599.98. The JBL 4367’s replacement, the JBL 4369, is rated 4.7/5.
The case for the Klipsch Heresy IV: Very high 94.5dB/2.83V/1m sensitivity in Erin’s anechoic measurement (well below Klipsch’s 99dB in-room claim, but still excellent) and strong short-term output from a 12-inch woofer plus horn-loaded midrange and tweeter. Watch for: Erin measured a 77Hz F3 and response rolling away near 100Hz in-room, so a subwoofer is required for modern full-range reproduction.
The JBL 4367 is the more accurate, deeper-bass 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 2.27 for the Klipsch Heresy IV. Its bass reaches about 43Hz before falling 3dB, against 77Hz for the Klipsch Heresy IV. The tradeoff: At roughly $16500/pair, this is a major investment: the reviewer recommends buying from a dealer with a liberal return policy.
Buy the Klipsch Heresy IV, since the JBL 4367 is discontinued and only worth hunting down used.

Klipsch Heresy IV: $3,599.98 per pair Amazon Crutchfield eBay
Same family: the Klipsch Forte IV (larger floorstanding, ranked higher, rated 4/5), the Klipsch Cornwall IV (larger floorstanding, ranked higher, estimated 2.8/5), the Klipsch La Scala AL6 (larger floorstanding, ranked higher, estimated 2.8/5) and the Klipsch Klipschorn AK7 (larger floorstanding, ranked higher, estimated 3/5).
Pros: Very high 94.5dB/2.83V/1m sensitivity in Erin’s anechoic measurement (well below Klipsch’s 99dB in-room claim, but still excellent) and strong short-term output from a 12-inch woofer plus horn-loaded midrange and tweeter. The compact, furniture-grade Heritage cabinet is easier to place than most high-efficiency designs, and dynamics at moderate levels can sound lively. A stable four-ohm-capable amplifier can produce substantial SPL with relatively little voltage. Measured bass extension of 77Hz (-3dB), with a measured sensitivity of 94.5dB.
Cons: Erin measured a 77Hz F3 and response rolling away near 100Hz in-room, so a subwoofer is required for modern full-range reproduction. The impedance dips to about 4 ohms, reducing the practical amplifier advantage implied by its sensitivity. Pronounced directivity mismatch at the driver transitions, impedance/response resonances and elevated distortion spikes around the crossover remain audible concerns that EQ cannot fully solve. At 102dB Erin measured roughly 1.5dB midband compression; at 96dB distortion rises around crossover. Performance is difficult to justify at the price, and Erin explicitly did not recommend it.

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.
