Fibreglass Cone Midrange
The Discovery series is designed for the discerning audiophile and to meet the needs of this demanding audience, Scanspeak have developed several new technologies to help reduce distortion and damping within the speaker.
Key Features:
- NRSC Fibreglass Cone
- Phase plug for improved phase linearity
- Very low damped coated foam surround
- Aluminium magnet ring for improved impedance control and lower distortion
- Die cast Aluminium chassis
- Vents below spider
- Non resonant suspension coupling
