Short answer: the JBL HDI-3600 for output and flat response, the Revel F35 for value. The HDI-3600’s CEA2034 spinorama shows a fairly even on-axis and flat response with high 90dB sensitivity and very low midrange distortion, though a wide shelving-down above 2kHz affects the in-room response. The F35’s four-driver, waveguide-loaded layout is the cleaner buy, but it needs a subwoofer at an F3 of 61Hz and F10 of 39Hz.
Buy the Revel Concerta2 F35. It is rated higher for sound quality than the JBL HDI-3600 and costs less, so only choose the other one for a particular feature it does better.

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.

JBL HDI-3600: $3800 per pair Audio Advice eBay
Pros: CEA2034 spinorama shows a fairly even on-axis response and flat overall frequency response, with high 90dB sensitivity and very low distortion through the midrange. Triple 6.5” Advanced Aluminum Matrix woofers and a 1” compression driver in JBL’s HDI waveguide. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: A wide shelving-down above 2kHz affects the in-room response, and vertical dispersion is a bigger issue than horizontal: the reviewer noted the dip is wider here than on the smaller HDI-1600, making it more audible. Narrow vertical sweet spot means careful listener-height positioning matters more than usual.
