Step into the future and experience the Hologram M3. The latest research from Clayton Shaw's quarter-century of development into open-baffle technology has yielded a beautifully natural and transparent sounding loudspeaker with the deep emotional connection of the real thing. A virtual image seems to project through the wall boundaries into open space for an unforgettable listening experience. All Hologram models can be used in a wide range of room sizes without the room boom associated with box speakers. Hear life-like dynamics and emotional impact with the liquid sounding M3.  All passive, analog design - no digital signal processing required.

New Turbo S Version now available. An evolutionary step beyond the M3 Turbo, the Turbo S version incorporates our new M25 compression driver with specially treated titanium diaphragm which increases stiffness to reduce distortion even further. The world's best sub $5000 speaker just got better. 

Design by Clayton Shaw • Engineered and manufactured in the USA.
