Short answer: the JBL 4367 for better sound quality, the JBL HDI-3800 for the lower price. The JBL 4367 ranks #11 of 73 floorstanding speakers, rated 4.6/5, at $16,500. The JBL HDI-3800 ranks #14, rated 4.5/5, at $5,000, $11,500 cheaper.
Why pick the JBL HDI-3800: 2410H-2 1” Teonex compression driver matched to a custom High-Definition Imaging (HDI) horn geometry achieves exceptional horizontal directivity control, high output capability, and effortless transient response. The tradeoff: On-axis frequency response features a narrow upper-frequency elevation around 8-10kHz, performing noticeably smoother when toed out 10-20° off-axis.
The case for the JBL 4367: Three-way design pairing a 15” front-ported woofer with a compression driver on a controlled-dispersion horn/waveguide, crossed over at 700Hz. Watch for: At roughly $16500/pair, this is a major investment: the reviewer recommends buying from a dealer with a liberal return policy.
One note: the JBL HDI-3800 is discontinued, but it still ranks #14 of 73 floorstanding speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the JBL HDI-3800 if the price is the priority over sound quality, or the JBL 4367 if sound quality is the priority over the price.

JBL HDI-3800: $5,000.00 per pair Discontinued eBay
Pros: 2410H-2 1” Teonex compression driver matched to a custom High-Definition Imaging (HDI) horn geometry achieves exceptional horizontal directivity control, high output capability, and effortless transient response. Triple 8” Advanced Aluminum Matrix woofers deliver deep, authoritative bass extension down to an F3 of 37Hz and F10 of 28Hz with minimal low-frequency compression. Outstanding sensitivity (92dB SPL at 2.83V/1m) and ultra-low THD/multitone distortion allow extremely high undistorted SPL output in large home theater spaces. Measured bass extension of 37Hz (-3dB), with a measured sensitivity of 92dB.
Cons: On-axis frequency response features a narrow upper-frequency elevation around 8-10kHz, performing noticeably smoother when toed out 10-20° off-axis. Vertical directivity handoff across the triple woofer layout creates vertical soundstage height tilt depending on listening distance and ear height. Minimum impedance dips to 3.8 ohms, requiring high-current amplifier stability. Substantial cabinet dimensions and 38kg weight require significant room real estate. Discontinued.

JBL 4367: $16500 per pair Discontinued eBay
Newer model: the JBL 4369. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
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.
