#113 Q Acoustics 5040: $3,998 per pair Amazon $1,999.00 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: Well-built floorstanding speakers that are easy to drive, playing loud on modest amplifiers with a smooth, well-integrated midrange. 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.
