These are not really the same size class, and that is the honest framing here. The Q Acoustics 5050 ranks #55 of 139 floorstanding speakers by sound quality at $2,499; the Q Acoustics 5090 ranks #47 of 98 center channel speakers by sound quality at $799.
What the Q Acoustics 5050 does well: Flagship floorstanding tower in the 5000 Series with dual 6.0-inch C3 Continuous Curved Cone woofers, internal HPE tubes, and P2P bracing. Watch for: Rating estimated based on 5000 series sibling testing.
What the Q Acoustics 5090 does well: Dual 4.5-inch C3 Continuous Curved Cone woofers paired with high-performance Point-2-Point internal bracing. The catch: Impedance drops to 3.2 ohms minimum at bass frequencies.
Buy the Q Acoustics 5050 at $2,499 if you want a floorstanding speaker. Buy the Q Acoustics 5090 at $799 if you want a center channel speaker instead.
