Short answer: the Ascend Acoustics Sierra Titan Tower. It ranks #25 of 73 floorstanding speakers by sound quality, rated 4.4/5, at $2,998. The Q Acoustics 5040 ranks #41, rated 4.1/5, at $2,472.98, $525.02 cheaper, which does not close the gap in sound quality.
What the Ascend Acoustics Sierra Titan Tower does well: A SEAS Titan dome tweeter and dual 5.25 inch long throw woofers in a bamboo V-LAM tower reach a measured 58.6Hz extension point at a more accessible price than Ascend’s ribbon tweeter ELX line. Watch for: Its listening window response is the least smooth of Ascend’s measured towers, trailing the pricier ELX Ribbon Tower.
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 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.
Buy the Ascend Acoustics Sierra Titan Tower. It is rated higher for sound quality, and saving $525.02 with the Q Acoustics 5040 does not make up for the sound-quality gap.

Ascend Acoustics Sierra Titan Tower: $2,998 per pair Ascend Acoustics eBay
Pros: A SEAS Titan dome tweeter and dual 5.25 inch long throw woofers in a bamboo V-LAM tower reach a measured 58.6Hz extension point at a more accessible price than Ascend’s ribbon tweeter ELX line. The bass alignment Q of 0.72 keeps the low end reasonably well controlled. Backed by the same 7 year parts and labor warranty and hand matched +/-1.5dB pairs, each shipped with its own production line frequency response printout. Measured bass extension of 58.6Hz (-3dB).
Cons: Its listening window response is the least smooth of Ascend’s measured towers, trailing the pricier ELX Ribbon Tower. Sound power response falls off more steeply above the crossover than the ribbon version, so off axis and in room treble energy rolls off faster. Ascend sells direct only, with no dealer network or third party retailers for an in person audition.

Q Acoustics 5040: $2,472.98 per pair Amazon eBay
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.
