Description
HELIX S 3M
A cone midrange driver in an elegant design, trimmed for maximum sound quality – and thus the perfect addition to any fully active 3-way speaker system.
The highly rigid membrane consists of a novel basalt fiber-paper compound. An ideal combination to ensure clear and precise sound even at high volumes? In addition to maximum uncoloured mid-range reproduction, the S 3M also offers extremely low distortion thanks to the linear neodymium magnet system.
The dream team is the combination with the S 1T tweeter and a S 6B or S 4B woofer. Driven by a power amplifier from Audiotec Fischer, the S loudspeakers perform at their best and provide the perfect basis for absolute top sound systems!
Features
- 3? / 75 mm cone midrange speaker with novel basaltfiberpaper compound cone – a perfect combination of lowest weight, high stiffness and perfect inner damping
- Highly efficient, compact neodymium magnet system for linear drive and minimum distortion
- Low-resonant basket made from glassfiber reinforced plastic with optimized voice coil cooling for high power handling
- Grille included
