Helix Audiotec Fischer S 6B  6.5” / 165 mm Car Door Mid-Woofer High End Audio

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 6B 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!

6.5” / 165 mm mid-woofer with novel basalt-fiber-paper compound cone – a perfect combination of lowest weight, high stiffness and inner damping

Specially shaped rubber surround for larger effective cone area and increased maximum excursion
