Short answer: the KEF Q11 Meta, if you are buying new. The JBL HDI-3800 ranks higher than it (#25 vs #103 of 188 floorstanding speakers, 4.5/5 vs 4.0/5) but is discontinued, so only consider it used; the KEF Q11 Meta is still sold new at $2,499.98.
The KEF Q11 Meta is the more accurate choice. Three-way tower design with a coaxial layout: a 3/4” aluminum dome tweeter (with KEF’s Metamaterial Absorption Technology behind it) mounted at the center of a 4” mid-range, plus three 6.5” bass drivers. Its measured preference score, a predictor of how neutral it sounds, is 6.72 against 5.62 for the JBL HDI-3800. Watch for: Genuinely dark-sounding on raw on-axis measurement, and needs a typical room with sidewall reflections (within about 6 feet/2 meters) to sound properly neutral: in a large room with little sidewall interaction, it may sound too dull for some listeners.
The JBL HDI-3800 is the better-sounding, deeper-bass option. 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. Its bass reaches about 37Hz before falling 3dB, against 60Hz for the KEF Q11 Meta. 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.
Buy the KEF Q11 Meta new; the JBL HDI-3800 is no longer sold new, so it only makes sense as a used find.

KEF Q11 Meta: $2,499.98 per pair Amazon eBay
Same family: the KEF Q1 Meta (smallest bookshelf, rated 3.6/5), the KEF Q4 Meta (bookshelf, estimated 3.4/5), the KEF Q3 Meta (bookshelf, rated 3.4/5), the KEF Q Concerto Meta (largest bookshelf, rated 4.6/5), the KEF Q7 Meta (smaller floorstanding, ranked lower, estimated 3.5/5) and the KEF Q6 Meta (center, rated 3.9/5).
Pros: Three-way tower design with a coaxial layout: a 3/4” aluminum dome tweeter (with KEF’s Metamaterial Absorption Technology behind it) mounted at the center of a 4” mid-range, plus three 6.5” bass drivers. Extremely linear estimated in-room response when placed correctly, thanks to a deliberately declining on-axis response paired with well-controlled directivity: a technically sound design philosophy, even though it reads as “dark” in raw anechoic on-axis measurements. In-room bass extension to about 40-50Hz when placed near a wall, thanks to extended bass-shelf tuning. Sounds excellent whether pointed directly at the listener or toed out a full 30° parallel to the back wall: unusually flexible placement. More vertical listening leeway than standard non-coaxial two-way designs, thanks to the coincident tweeter/midrange. Distortion looks good at both 86dB and 96dB, and multitone distortion holds up well too. Comes with a plinth/outrigger kit for stability given its floorstanding height (about 43-44”). Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 88.6dB.
Cons: Genuinely dark-sounding on raw on-axis measurement, and needs a typical room with sidewall reflections (within about 6 feet/2 meters) to sound properly neutral: in a large room with little sidewall interaction, it may sound too dull for some listeners. Must be placed close to a rear wall (about 1 foot) to get proper bass: pulling it out to the “standard” 3-foot audiophile recommendation causes bass output to drop off noticeably. Horizontal radiation of about ±50° is narrower than the reviewer’s preferred ±60°, giving a slightly less enveloping soundstage than some rivals. Notably darker than sibling KEF models in the same product family: measures 2-5dB less top-end energy than the R3 Meta and a few dB less than the Q Concerto Meta. Minor lingering resonances appear in burst decay measurements between 500Hz-1kHz. The tweeter shows some strain at very high output volumes, a limitation the reviewer notes is common even among more budget-friendly speakers generally.

JBL HDI-3800: $5,000 per pair Discontinued eBay
Same family: the JBL HDI-1600 (bookshelf, rated 4.2/5), the JBL HDI-3600 (smaller floorstanding, ranked lower, rated 4.3/5) and the JBL HDI-4500 (center, rated 3.7/5).
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.
