The unit mass of the membrane of Sound Lab speakers is significantly less than the mass of the air load it is moving. In fact, our speakers probably have the lowest moving mass of any speaker on the market. The benefits of this are several. When the membrane is commanded to stop or start, it does so without the delay that higher mass speakers exhibit. Also, since air-mass has the greatest influence on transduction characteristics, the speaker inherits the optimum damping characteristics of air.
Transients are crisper and cleaner.
Detail is much more apparent. Secondly, the force that drives the membrane of our electrostatic speakers is evenly distributed over the entire radiating surface. As a result, the membrane can be very thin and flexible. Due to optimum damping and excellent signal compliance, distortion and irritation factors are extremely low. This development not only provides a flat, extended bass response but it also eliminates the undesirable membrane resonance peak.
