Overview
The Cinema Ribbons are feature-
rich, high-tech, but most importantly
GREAT SOUNDING loudspeakers.
Years of research and decades of
experience have gone into these small
wonders.
The Cabinet
The Cinema Ribbons feature a carefully designed cabinet that stems from years of
research into how the box affects the sound of the loudspeaker. The specialized facets
of the Cinema Ribbon have the appearance of a Stealth airplane, and result in a loud-
speaker that is free of unwanted sonic bounces.
The Ribbon – A Legacy Re ned
The ribbon in this loudspeaker is a remarkable piece of engineering, because it has
the output capability, purity, and low distortion of a large 6-foot-tall ribbon – in fact, it is
derived from Bob Carver’s award-winning Amazing Loudspeaker from the late 1970s!
The sound from the CRM-2 ribbon is deliberately focused in the forward direction, with
very little sound going up or down – reducing re ections off the ceiling and oor, that
disturb our sense of space and imaging. The CRM-2C features an integrated “acoustic
lens,” that disperses the signal for center channel applications.
The Woofers – A Legacy Re ned
Sun re created the category of small-box, high-power subwoofers more than a
decade ago with the original True Subwoofer. This design relies on high-pressure, “High
Back-emf” technology that provides very high bass output from a very small box. When
migrating this subwoofer technology to the midrange and high frequencies on the Cin-
ema Ribbons, you get the same advantages: high output, small size, high ef ciency, and
years of trouble-free operation.
Sun re has found that our ears are very sensitive to certain frequencies which our
brains use to develop clues as to the size and location of sounds. Bob Carver and team
created an electrical circuit called Sonic Holography back in the 1970s that took this
into account – and to this day it’s included on Sun re’s processors and receivers. In the
CRM-2 Cinema Ribbons, these critical octaves are output primarily from the two side-
ring drivers. This introduces the room as part of the musical instrument by intentionally
bouncing the sound off of walls and oors, creating a time delay to enlarge the sense
of acoustic space, in all dimensions. This is a noted difference from what we looked at
previously with the ribbons – it is a very calculated (and very important) distinction. The
CRM-2C features front- ring drivers to maintain focus for dialog in center channel ap-
plications.
Conclusion
The combination of a focused, front- ring ribbon and the omnidirectional, side- ring
woofers creates a large sense of space with very precise imaging within that space.
Depending on the loudspeaker location and demo material, you also are able to discern
a sense of front-to-back depth with layered textures of musical instruments playing and
performing in thin air! Happy listening!
