HELIX Audiotec Fischer S 1T 1" Silk Dome Tweeter 100W Rms Authorised Dealer

A tweeter for the good sound – Only the tweeters provide the perfect sound experience in a sound system. 

The coated silk dome and the highly efficient neodymium magnet of the S 1T implicate an unique sensitivity in the high-frequency reproduction and crystal clear sound. The high-grade mounting cup made from anodized aluminum with removeable grille offers optimum protection of the dome and impresses in an exclusive HELIX design.

The special highlight: The tweeter unit can be taken out of the mounting cup. Thus, the already very compact dimensions can be reduced and offers optimum preconditions for easy integration into the vehicle.

One thing´s for sure: The new S 1T tweeters turn every sound system into a "high"-light!
