Looks can be deceiving. Despite its slim dimensions, 704 S2 has the commanding presence of a much larger speaker, thanks to advanced technologies such as a dedicated Continuum™ cone FST™ midrange.
With the 704, music is a revelation, with details picked out in pin-sharp detail and with exceptional realism.
Carbon Dome tweeters are a brand new technology purpose-built for the 700 Series. Delivering a dramatic improvement on the aluminum 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 floorstanders feature decoupled design, adapted from a similar system in the 800 Series Diamond. Decoupling reduces cabinet coloration, and boosts midrange clarity.
Developed using advanced computer modeling techniques, the Aerofoil™ Profile bass cone has variable thickness, providing stiffness and rigidity where it’s needed most. The result: deep and dynamic bass.
