Product information "Helix S 6B - 16.5cm bass-midrange driver"

HELIX S 6B

A low-midrange speaker in an elegant design, trimmed for maximum sound quality.
The highly rigid membrane consists of a new type of basalt fiber-paper compound. A perfect combination to guarantee clear, unadulterated sound even at high volumes. In addition to powerful bass reproduction and incomparably neutral mids, the S 6B also shines with extremely low distortion.

The dream team is the combination with the S 1T tweeter, which ideally expands the frequency range. In conjunction with a power amplifier from Audiotec Fischer, the S speakers are at their best and provide the perfect basis for absolute top sound systems!

Features

  • 165 mm bass-midrange driver with a new basalt fiber-paper compound membrane - an ideal combination of low weight, high rigidity and internal damping
  • Specially shaped rubber surround for larger effective membrane area and extended maximum stroke
  • Basket in individual HELIX design with additional ventilation openings for optimized cooling of the voice coil for high resilience
  • Solid rubber protection with HELIX logo for the magnet systems
  • Gold-plated connection terminals
