Elegantly 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!

Specially shaped rubber surround for larger effective cone area and increased maximum excursion
Individual HELIX basket with additional ventilation holes for better voice coil cooling and high power handling
