I was tooling around the B&W site when I came across their new top end center channel. Check this baby out. Three, yes, THREE eight inch woofers, one Six inch FST midrange and one, one inch diamond tweeter. AND the Midrange and tweeter are in their own respective Marlan enclosures like the rest of the 800 series. Oh yeah, and it weighs 205 LBS!!!!!!
From B&W:
The HTM1D is the largest of four centre speakers in the 800 Series. It could be considered an 802D with a different aspect. The full configuration of FST™ midrange in a Marlan® sphere/tube 'head' with diamond dome tweeter on top is used, so that the system perfectly voice matches either the 800D, 801D or 802D in a substantial and powerful multi-channel installation.
To supply the prodigious bass power necessary to keep up with these powerful main speakers, the HTM1D uses three 200mm (8 in) diameter Rohacell® cone drivers with twin rear-firing Flowports™. All drivers are, of course, magnetically shielded to avoid picture distortion with CRT-based screens.
The HTM1D is specifically intended to be mounted on the floor, its low profile allowing a large projection screen to come within 600mm (2 ft) of the floor. Supplied with the system are four heavy-duty height-adjustable feet. This design allows up to 40mm (1.6 in) of vertical adjustment so that the speaker may be tilted back to face more towards the listeners. They have a case hardened spike at one end for carpeted floors, and a non marking rubber pad on the other for more vulnerable surfaces.
