Short answer: the Q Acoustics 5040 if sound quality matters most, the JBL Stage 2 280F if price matters most. The Q Acoustics 5040 ranks #113 of 226 floorstanding speakers, rated 4.1/5, at $4,014.96. The JBL Stage 2 280F ranks #187, rated 3.4/5, at $1,319.90, $2,695.06 cheaper.
The Q Acoustics 5040 is the better-sounding pick. C3 (Continuous Curved Cone) driver profile technology provides smooth midrange integration, controlled cone breakup, and improved bass damping. The tradeoff: Free-field frequency response exhibits a noticeable mid-bass scoop around 200Hz (~6dB lower than mean SPL), causing an F3 of 70Hz (F10 of 39Hz) in open space and requiring boundary placement (11-22 inches from front wall) to reinforce upper bass output.
The JBL Stage 2 280F is the more accurate, deeper-bass choice. 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 measured preference score, a predictor of how neutral it sounds, is 4.69 against 3.80 for the Q Acoustics 5040. Its bass reaches about 48Hz before falling 3dB, against 70Hz for the Q Acoustics 5040. 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 Q Acoustics 5040 when sound quality outweighs the price for you, and the JBL Stage 2 280F when the price outweighs sound quality instead.

Q Acoustics 5040: $4,014.96 per pair Amazon eBay
Same family: the Q Acoustics 5010 (smaller bookshelf, estimated 3.5/5), the Q Acoustics 5020 (larger bookshelf, rated 2.2/5), the Q Acoustics 5050 (larger floorstanding, ranked higher, estimated 4.3/5) and the Q Acoustics 5090 (center, estimated 3.7/5).
Pros: C3 (Continuous Curved Cone) driver profile technology provides smooth midrange integration, controlled cone breakup, and improved bass damping. High voltage sensitivity (91.5dB SPL at 2.83V/1m) allows loud listening with low-to-moderate amplifier wattage. Cabinet features Point-to-Point (P2P) internal bracing and Helmholtz Pressure Equalizer (HPE) tubes to suppress internal standing waves and panel vibrations. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 91.5dB.
Cons: Free-field frequency response exhibits a noticeable mid-bass scoop around 200Hz (~6dB lower than mean SPL), causing an F3 of 70Hz (F10 of 39Hz) in open space and requiring boundary placement (11-22 inches from front wall) to reinforce upper bass output. Measurements indicate an enclosure resonance near 300Hz visible in sound power data. Minimum impedance drops to 3.0 ohms, demanding a stable 4-ohm rated amplifier despite high sensitivity.

JBL Stage 2 280F: $1,319.90 per pair Amazon eBay
Older model: the JBL Stage A180 (ranked higher, rated 3.8/5). See every JBL Arena and Stage generation.
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.
