Short answer: the JBL HDI-3800, because the Revel Concerta2 F35 needs a subwoofer for real bass. The F35 is a two-and-a-half-way, four-driver tower with a 1-inch aluminum dome tweeter on a waveguide, a 5.25-inch midrange and dual 5.25-inch midbass drivers, but an F3 of 61Hz and F10 of 39Hz leave it short on low end. The HDI-3800’s 1-inch Teonex compression driver and HDI horn add exceptional horizontal directivity, high output and effortless transients.
Buy the Revel Concerta2 F35 if you want one new; the JBL HDI-3800 is discontinued, so only look for it used.

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 Concerta2 F35: $900 per pair Crutchfield eBay
Pros: Two-and-a-half-way, four-driver design: a 1” aluminum dome tweeter on a waveguide, a 5.25” mid-range, and dual 5.25” mid-bass drivers in a rear-ported cabinet. Measured sensitivity of 89.4dB closely matches the 90dB spec, and distortion looks good at both 86dB and 96dB, holding up well even with a high-pass filter applied. At its sale price of $900/pair, down from full retail, the reviewer calls it a “no-brainer,” undercutting comparable budget floorstanders like the ELAC DF63. Frequency response and directivity mismatches are largely EQ-able, since most of what shows up in measurements traces to physical tweeter/mid-range separation rather than a fundamental flaw. Compression is fairly well controlled for the price: about 1dB of loss around 100Hz under long-term compression, described as “par for the course” at this cost. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 89.4dB.
Cons: F3 of 61Hz and F10 of 39Hz mean a subwoofer is needed for real bass extension. A dip in the lower midrange/2-3kHz region reduces attack and detail, and a peak around 5kHz adds some edge and sibilance in the lower treble. A peak in off-axis energy around 3kHz reflects off sidewalls at roughly 60-70° off-axis and arrives louder than the direct sound: this specific issue can’t be fixed with EQ (boosting the direct sound would boost the stronger reflection too) and would need acoustic absorption to properly address, though the reviewer considers it a minor, optional fix at this price. A couple of minor resonances appear in the impedance plot, including one around 300Hz that may partly explain a subtle sense of vocal warmth noticed in listening, though it’s more likely room-related. Minimum impedance around 3.8 ohms. Short-term compression testing shows some increased distortion in the tweeter and higher-frequency compression at loud output.
