To supply the prodigious bass power necessary to keep up with these powerful main speakers, the HTM1D uses three 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.
