The centre of your multichannel system
Designed to match the larger 800 Series Diamond speakers, the HTM1 D3 is the ultimate centre channel speaker.
Hear small details in a big way
Mounted atop the main enclosure, the Diamond dome tweeter in its solid aluminum housing delivers space, ambience and precise soundstage imaging.
Truly amazing sound
Voices and instruments are delivered with purity and precision, thanks to the smooth, accurate Continuum™ cone mid/bass driver.
Nimble and powerful
