B&W HTM 7
From HifiWiki
[edit] Description
- Manufacturer: B&W
The HTM7 utilises a similar driver line-up to the 705 and is timbre matched to the other speakers in the range for use in a 700 Series-based home theatre installation. For its centre channel role, the cabinet is wider and lower to give a better aspect when placed on top of or immediately below a television. Naturally, the drivers are magnetically shielded to avoid picture distortion. Threaded inserts in the base of the speaker are provided to enable a direct screw fixing to the FS-700 speaker stand.
