The key element in the design of SLS's loudspeakers is their Push Pull Neodymium Ribbon Driver Technology . These ribbons combined with their proprietary wave guides, woofers, and cabinet designs create loudspeakers with world-class performance. SLS has developed a way to manufacture their loudspeaker drivers with new materials and are able to achieve extremely high output levels with fast transient response and ultra low distortion.
SLS's high frequency ribbon drivers are capable of producing accurate sound over a wider dynamic range. These design considerations result in loudspeakers that are capable of unprecedented audio detail at high sound levels with much less listener fatigue.
"I love these speakers for the way they let dynamic contrasts jump out. Most speakers sound closed-down or blah by comparison."
Steve Guttenberg of Home Theater -- March 2002 Issue
The SLS Planar Ribbon Drivers feature a Kapton diaphragm with an etched aluminum conductive trace that is symmetrically driven by powerful Neodymium magnets. Kapton was selected because it's lightweight and can handle temperatures as high as 750 degrees Fahrenheit. In fact, the mass of this planar ribbon diaphragm is over 100 times lighter than a typical four inch Titanium compression driver diaphragm. It's over 50 times lighter than a typical HiFi dome tweeter diaphragm.
The result is a driver with incredibly fast transient response, ultra low distortion, high sensitivity and extended frequency response beyond 40 kHz. The flat radiating surface of the ribbon is ideal for the radiation of sound and it is truly isophasic . The sound emanates from the ribbon as a coherent wave front that is free from resonance, cancellations or delays.
It's a minimalist approach to producing sound with out compression chambers, throats, phase plugs, or voice coil formers. There are no obstructions and ribbon diaphragm is ideally coupled to the air load in front of it so the sound expands naturally with even dispersion over its entire frequency range. We even use a proprietary progressive damping technique to effectively absorb the rear-radiated sound preventing it from reflecting out the front of the diaphragm.
