S 4B
Elegant designed mid-woofer trimmed for maximum sound quality.
The extremely rigid cone consists of a novel basalt-fiber-paper compound – the perfect combination to guarantee clear and straight sound even at high volume levels. Beside a powerful bass reproduction and peerlessly neutral mids, the S 4B impresses with exceptionally low distortion.
A dream team is the combination with the S 1T tweeter that ideally complements the frequency range. Together with an Audiotec Fischer power amplifier, the S loudspeakers strike up to top form and provide the perfect basis for absolute top sound systems!
