Short answer: the MoFi SourcePoint 888. It ranks #10 of 25 floorstanding speakers at $5500; the JBL 4367 ranks #11 and costs $16500, so there is not much of a tradeoff to weigh.
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. Set against that: At roughly $16,500/pair, this is a major investment - the reviewer recommends buying from a dealer with a liberal return policy.
What the MoFi SourcePoint 888 gets right: Three-way vented design: an 8” coaxial mid-range/1.25” dome tweeter driver plus two additional 8” woofers crossed at about 130Hz. The catch: A significant investment, best ordered from a dealer with a good return policy.

The Two Speakers In Full
JBL 4367: $16500
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.
Cons: At roughly $16,500/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).

MoFi SourcePoint 888: $5500 Crutchfield
Pros: Three-way vented design: an 8” coaxial mid-range/1.25” dome tweeter driver plus two additional 8” woofers crossed at about 130Hz, giving genuinely full-range output (F3 34Hz, F10 26Hz) other than the deepest subsonic content. Ranked by the reviewer among his personal top three speakers out of roughly 200 tested, alongside the KEF Blade 2 Meta and Dutch & Dutch 8C, despite costing a small fraction of either. Excellent compression/dynamic-range linearity, holding its own against much pricier speakers like the March Audio Sointuva AWG, KEF Reference 1 Meta, and KEF Blade 2 Meta. On-axis (0°) and 30°-off-axis estimated in-room responses track within about 1-1.5dB of each other above 500Hz, so tonal balance barely changes with placement or listening angle - excellent for multi-seat home theater or entertaining. Wide horizontal dispersion of about ±60°. Distortion stays low: under 1% at 86dB, and under 1% above 200Hz even at 96dB, with multitone distortion mostly under 1% as well. Not a difficult amplifier load (5-ohm minimum impedance, 4.2-ohm minimum EPDR). Checks the three boxes the reviewer considers essential for a home theater speaker: low compression, low distortion, and excellent directivity.
Cons: A significant investment, best ordered from a dealer with a good return policy. Large and heavy floorstander (about 96 lbs, 42” tall) requiring real floor space and rear clearance. Positioning is fairly specific: needs about 2 feet from the rear wall - closer causes boominess in the 40-50Hz region, farther loses bass extension. Vertical dispersion (about ±50°) is narrower than horizontal (about ±60°), since the two 8” woofers are spaced vertically apart on a tower cabinet, causing some vertical mismatch at lower frequencies. A small on-axis dip around 500Hz and a deliberately lower tweeter level (about 0.5dB below the midrange) are intentional design choices for smoother in-room response, but mean the raw on-axis measurement isn’t perfectly flat. A mild diffraction-related dip appears around 3kHz in directivity measurements. Toeing the speaker out more than about 10° starts to noticeably reduce top-end energy.
