#59 MartinLogan Motion B10: $1,039.98 per pair Crutchfield eBay
Same family: the MartinLogan Motion F10 (smaller floorstanding, estimated 3.8/5), the MartinLogan Motion F20 (larger floorstanding, estimated 3.9/5) and the MartinLogan Motion C10 (center, estimated 3.7/5).
Pros: MartinLogan’s folded-motion tweeter technology (a 9.2 sq in diaphragm, larger than a typical dome) reaches this price point, with an excellent sound-power smoothness score of 0.111, meaning its off-axis output tracks its on-axis response unusually well. Sensitivity of 92dB makes it easy to drive. Measured bass extension of 74.7Hz (-3dB).
Cons: On-axis deviation of 0.669dB is rough for the price, with a pronounced +0.32dB per octave upward tilt giving it a notably bright balance, and predicted in-room smoothness of just 0.16, the roughest of any speaker measured here. Bass extension is shallow too, a Harman in-room estimate of just 62Hz.
