These sit in different size classes, so this is not a straight ranking comparison. The Q Acoustics 5040 ranks #77 of 139 floorstanding speakers by sound quality at $2,472.98; the Q Acoustics 5010 ranks #60 of 122 bookshelf speakers by sound quality at $999.
What the Q Acoustics 5040 does well: C3 (Continuous Curved Cone) driver profile technology provides smooth midrange integration, controlled cone breakup, and improved bass damping. Watch for: 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 case for the Q Acoustics 5010: Compact 2-way standmount speaker in the 5000 Series featuring a 4.5-inch C3 Continuous Curved Cone mid/bass driver and hermetically sealed 1-inch tweeter. The tradeoff: Rating estimated based on 5000 series sibling testing.
Buy the Q Acoustics 5040 at $2,472.98 if you want a floorstanding speaker. Buy the Q Acoustics 5010 at $999 if you want a bookshelf speaker instead.

The Two Speakers In Full
Q Acoustics 5040: $2,472.98 per pair Amazon eBay
Smaller models: the Q Acoustics 5020 (rated 2.2/5) and the Q Acoustics 5010 (estimated 3.5/5).
Larger model: the Q Acoustics 5050 (ranked higher, estimated 4.3/5).
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.

Q Acoustics 5010: $999.00 per pair Estimated Amazon eBay
Larger models: the Q Acoustics 5020 (ranked lower, rated 2.2/5), the Q Acoustics 5040 (rated 4.1/5) and the Q Acoustics 5050 (estimated 4.3/5).
Pros: Compact 2-way standmount speaker in the 5000 Series featuring a 4.5-inch C3 Continuous Curved Cone mid/bass driver and hermetically sealed 1-inch tweeter. Provides low harmonic distortion and clean off-axis directivity matching the tested 5020 sibling.
Cons: Rating estimated based on 5000 series sibling testing. Modest low-frequency cutoff of 56Hz (-6dB) and 86.3dB sensitivity make it best suited for smaller listening environments or nearfield setups.
