#34 MartinLogan Motion XT C100: $1,599.99 Estimated Crutchfield eBay
Pros: Flagship 2.5-way center channel featuring larger Gen2 FMT XT tweeter with 40% more surface area and dual 6.5-inch Nomex-reinforced Kevlar woofers. High 93dB sensitivity and extended low-end response down to 42Hz.
Cons: Large 24-inch cabinet depth and width require substantial shelving. 4-ohm nominal impedance demands robust amplification. Rating estimated from Motion XT testing.
How it compares: Just above it: KEF Q250c - $1000 cheaper, 6Hz lower bass extension (-3dB). Just below it: Klipsch RP-504C II - $1100 cheaper, 3Hz higher bass extension (-3dB).
