"I find myself constantly shuffling through my music collection just to hear what they can do. They’re proving rather addictive…"
“These speakers sound as great as they look.”
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.
Less resonance, more dispersion
The Turbine Head's massive midrange housing is carefully shaped and inert, ensuring voices and instruments are delivered with extreme purity.
Truly amazing sound
Voices and instruments are delivered with purity and precision, thanks to the smooth, accurate Continuum™ cone midrange driver.
Nimble and powerful
Solid, dramatic bass is delivered through the rigidity and lightness of the uniquely-shaped, variable thickness Aerofoil™ cone.
Braced for impact
Unwanted resonances can blunt the punch of the sound: advanced Matrix bracing keeps the cabinet ultra-rigid and damps out superfluous vibrations.
Perfect sound is about moving air, not the speakers: a stable plinth makes for easy positioning, then keeps it rock-solid for listening.
