Description
The GF series is designed for the discerning audiophile customer. To meet the needs of this audience, several new technologies were developed with the goal of lowering distortion and damping in the speaker. The coated fibreglass cone reduces vibration and standing waves, and the vented motor system minimises power compression. The combined result is a very open and dynamic sound.
Features
- High Output 90dB @ 2.83V
- Coated NRSC Fibre Glass Cone
- Magnet System w. Alu Ring
- Low Damping SBR Rubber Surround
- Die cast Alu Chassis vented below spider
