Short answer: the Revel F328Be for a flat, efficient, superbly directed response; the JBL HDI-3800 for a simpler setup. The F328Be is quite flat on-axis with superb directivity and efficiency above 90dB, but its vertical directivity is asymmetric: the reviewer recommends sitting between -20 and +40 degrees relative to the tweeter axis. The HDI-3800 also offers exceptional horizontal directivity and high output, with a narrow 8-10kHz elevation best handled by toeing it out.
Buy the Revel F328Be. It is rated higher for sound quality and still sold new, while the JBL HDI-3800 is discontinued.

JBL HDI-3800: $5,000 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.

Revel F328Be: $19,359.90 per pair Crutchfield eBay
Pros: CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. Predicted in-room response is extremely accurate, with a smooth ~5dB downward slope from bass to treble that suits typical rooms without correction. Early reflections sum very nicely with the direct sound. Horizontal beamwidth of about ±70 degrees is wide and quite smooth. At 96dB SPL/1m distortion stays easily below the reviewer’s audibility threshold across nearly the whole range. Measured bass extension of 74Hz (-3dB), with a measured sensitivity of 91dB.
Cons: Vertical directivity is asymmetric: the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis, reflecting the driver layout of this three-way tower. Impedance dips to a minimum of 3 ohms with an additional resonance-driven phase swing, calling for an amplifier comfortable with a demanding load. Very expensive and very heavy (51 kg each).
