The HTM4S is the smallest of the centre speakers in the range and is effectively an 805S with a different aspect and the added feature of magnetic shielding. It is therefore the ideal centre speaker when assembling a high quality, yet compact home theatre system with the 805S looking after the left and right channels. The 165mm (6.5 in) woven Kevlar® cone bass/midrange driver features B&W's Balanced Drive for incredibly low midrange harmonic distortion. When you're listening to complex musical passages, or to dialogue amongst the background noise of an action movie, this is an essential attribute. The complementary FS-HTM floor stand provides the ideal support for the HTM4S, offering three tilt positions.
