#19 Bowers & Wilkins CWM 7.5 S2: $2,700 per pair Estimated Audio Advice eBay
Older model: the Bowers & Wilkins CWM7.5 (ranked lower, rated 2.6/5).
Pros: A Reference Series in-wall with a 1” Carbon Dome tweeter and a 5” Continuum cone, a forward-firing Flowport and a retrofittable integrated back box, rated 45Hz to 28kHz. Mounting depth is only 4 1/16”.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from its measured predecessor. Its predecessor measured poorly on axis, so the range is wide. Sensitivity is 86dB.
How it compares: Just above it: MartinLogan Tribute 5XW - $2150 more, 8Hz higher bass extension (-3dB). Just below it: KEF CI50R - 4Hz lower bass extension (-3dB).
