Compact Diamond centre
More compact than the HTM1 D3, this is the ideal speaker to partner with the smaller 800 Series Diamond models.
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
Solid, dramatic bass is delivered through the rigidity and lightness of the uniquely-shaped, variable thickness Aerofoil™ cone.
