Carbon Dome tweeters are a brand new technology purpose-built for the 700 Series. Delivering a dramatic improvement on the aluminium double dome tweeter, they raise the breakup threshold to 47kHz, for pinpoint imaging accuracy and detail.
Voices and instruments are delivered with purity and precision, thanks to the smooth, accurate Continuum™ cone midrange driver.
The midrange drivers in these floor-standers feature decoupled design, adapted from a similar system in the 800 Series Diamond. Decoupling reduces cabinet coloration, and boosts midrange clarity.
