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 Refi 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 refl ections off the ceiling and fl 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 Refi ned
Sunfi 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 effi ciency, and 
years of trouble-free operation.
Sunfi 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 Sunfi re’s processors and receivers. In the 
CRM-2 Cinema Ribbons, these critical octaves are output primarily from the two side-
fi ring drivers. This introduces the room as part of the musical instrument by intentionally 
bouncing the sound off of walls and fl 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-fi ring drivers to maintain focus for dialog in center channel ap-
plications.
Conclusion
 The combination of a focused, front-fi ring ribbon and the omnidirectional, side-fi 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!
