Short answer: the Klipsch Heresy IV for better sound quality, the JBL Stage 2 280F for the lower price. The Klipsch Heresy IV ranks #44 of 71 floorstanding speakers at $3198. The JBL Stage 2 280F ranks #62 at $659.95, $2538.05 cheaper.
What the Klipsch Heresy IV offers: Very high 94.5dB/2.83V/1m sensitivity in Erin’s anechoic measurement—well below Klipsch’s 99dB in-room claim, but still excellent—and strong short-term output from a 12-inch woofer plus horn-loaded midrange and tweeter. The compact, furniture-grade Heritage cabinet is easier to place than most high-efficiency designs, and dynamics at moderate levels can sound lively. A stable four-ohm-capable amplifier can produce substantial SPL with relatively little voltage. Watch for: Erin measured a 77Hz F3 and response rolling away near 100Hz in-room, so a subwoofer is required for modern full-range reproduction. The impedance dips to about 4 ohms, reducing the practical amplifier advantage implied by its sensitivity. Pronounced directivity mismatch at the driver transitions, impedance/response resonances and elevated distortion spikes around the crossover remain audible concerns that EQ cannot fully solve. At 102dB Erin measured roughly 1.5dB midband compression; at 96dB distortion rises around crossover. Performance is difficult to justify at the price, and Erin explicitly did not recommend it.
What the JBL Stage 2 280F offers: 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. Watch for: 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/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.
Buy the Klipsch Heresy IV if sound quality matters more than the price. Buy the JBL Stage 2 280F if the price matters more than sound quality.
If sound quality matters at all to you, skip the JBL Stage 2 280F. It ranks near the bottom of the 71 floorstanding speakers, so look higher up the list instead.
