Short answer: the Q Acoustics 5040 on measured sound quality, the Klipsch RP-5000F II on price. The Q Acoustics 5040 ranks #97 of 188 floorstanding speakers, rated 4.1/5, at $4,014.96. The Klipsch RP-5000F II ranks #105, rated 4.0/5, at $859.98, $3,154.98 cheaper.
The case for the Q Acoustics 5040: C3 (Continuous Curved Cone) driver profile technology provides smooth midrange integration, controlled cone breakup, and improved bass damping. The catch: 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 Klipsch RP-5000F II is the more accurate, deeper-bass option. The most tonally coherent of the RP II floorstander line, with a mild baffle-step dip and treble tilt but no additional coloration issues beyond that. Its measured preference score, a predictor of how neutral it sounds, is 5.24 against 3.80 for the Q Acoustics 5040. Its bass reaches about 55Hz before falling 3dB, against 70Hz for the Q Acoustics 5040. The catch: Bass extension is underwhelming for a floorstander (F3 at 55Hz, F10 at 41Hz) and needs a subwoofer.
Buy the Q Acoustics 5040 when sound quality outweighs the price for you, and the Klipsch RP-5000F II 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.

Klipsch RP-5000F II: $859.98 per pair B&H Photo Video eBay
Same family: the Klipsch RP-500M II (smaller bookshelf, rated 4/5), the Klipsch RP-600M II (larger bookshelf, rated 3.7/5), the Klipsch RP-6000F II (larger floorstanding, ranked lower, rated 3.9/5), the Klipsch RP-8000F II (larger floorstanding, ranked lower, rated 3.9/5), the Klipsch RP-404C II (smallest center, rated 3.7/5), the Klipsch RP-500C II (center, rated 3.9/5) and the Klipsch RP-504C II (largest center, rated 3.8/5).
Pros: The most tonally coherent of the RP II floorstander line, with a mild baffle-step dip and treble tilt but no additional coloration issues beyond that. Precise imaging thanks to the controlled horn/waveguide directivity. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 90dB.
Cons: Bass extension is underwhelming for a floorstander (F3 at 55Hz, F10 at 41Hz) and needs a subwoofer. Narrow horizontal dispersion (~50-60 degrees) trades soundstage width for imaging precision. A mild high-frequency tilt and a slight lack of detail around 1-1.5kHz.
