Short answer: the JBL HDI-3600. It ranks #58 of 188 floorstanding speakers by sound quality, rated 4.3/5, at $3,800. The JBL Stage 2 280F ranks #156, rated 3.4/5, at $1,319.90, $2,480.10 cheaper, which does not close the gap in sound quality.
The JBL HDI-3600 is the better-sounding pick. 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. The catch: 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 JBL HDI-1600, making it more audible.
The JBL Stage 2 280F is the deeper-bass pick. Genuinely impressive output capability and low compression/distortion for the price, courtesy of the dual 8” woofers: the reviewer’s standout praise for this pair. Its bass reaches about 48Hz before falling 3dB, against 78Hz for the JBL HDI-3600. The tradeoff: Explicitly called out as disappointing relative to expectations for the JBL name and this price point: lacks native linearity compared to similarly-priced alternatives like the Polk Reserve R500, which the reviewer recommends instead for anyone who doesn’t want to rely on EQ.
Buy the JBL HDI-3600. It is rated higher for sound quality, and the $2,480.10 you would save on the JBL Stage 2 280F does not close the gap.

JBL HDI-3600: $3800 per pair Audio Advice eBay
Same family: the JBL HDI-1600 (bookshelf, rated 4.2/5), the JBL HDI-3800 (larger floorstanding, ranked higher, rated 4.5/5) and the JBL HDI-4500 (center, rated 3.7/5).
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 JBL HDI-1600, making it more audible. Narrow vertical sweet spot means careful listener-height positioning matters more than usual.

JBL Stage 2 280F: $1,319.90 per pair Amazon eBay
Older model: the JBL Stage A180 (ranked higher, rated 3.8/5).
Same family: the JBL Stage 2 240B (smaller bookshelf, estimated 2.7/5), the JBL Stage 250B (larger bookshelf, rated 3.2/5), the JBL Stage 2 260F (smaller floorstanding, ranked higher, estimated 4.2/5), the JBL Stage 2 245C (center, estimated 3.2/5), the JBL Stage 200P (smaller subwoofer, estimated 3.5/5) and the JBL Stage 220P (larger subwoofer, estimated 3.7/5).
Pros: Genuinely impressive output capability and low compression/distortion for the price, courtesy of the dual 8” woofers: the reviewer’s standout praise for this pair. High sensitivity (89.5dB measured) and low impedance make it easy to drive. Decent bass extension (F3 48Hz, F10 30Hz) reaches about 50Hz in-room. Horizontal dispersion is reasonably consistent (~55 degrees), meaning the speaker takes reasonably well to EQ correction. Measured bass extension of 48Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: Explicitly called out as disappointing relative to expectations for the JBL name and this price point: lacks native linearity compared to similarly-priced alternatives like the Polk Reserve R500, which the reviewer recommends instead for anyone who doesn’t want to rely on EQ. Treble falls off a cliff above about 10-12kHz, giving a notable lack of air/space that needs real correction (a wide +Q0.5 boost from 10-20kHz) to fix. A sharp impedance resonance around 900Hz-1.1kHz is nearly impossible to EQ out cleanly even with narrow filters. Elevated multitone distortion in the 600Hz-2.5kHz range, tied to the midwoofer rather than the tweeter. Compared to the similarly-priced Klipsch RP-6000F II/Klipsch RP-8000F II, this JBL is less directive and native-flat but does extend roughly 20Hz deeper in the bass: a real tradeoff either way, not a clean win.
