Fostex FW 108 HR - Paper

The FW108HS is the woofer unit having high stiffness diaphragm evolved through the fusion of the unique sophisticated pulp materials and Fostex original paper making technology.

Certain transduction of amplitude into air vibration, new FW108HS woofer reproduces superb low frequency sound with remarkable transient.

- High stiffness diaphragm.
- Short voice coil.
- Ø100mm large ferrite magnet.
- Low current distortion magnetic circuit.
- Adequate acoustic parameters.
- Aluminum die-cast frame.

Key features:
  • 100mm (4 in) cone type full range
  • 8 ohm impedance
  • fo to 15kHz frequency response
  • 84.5dB sensitivity at 1W/1m (3.3ft)
  • 1.7kg (3.748 lb) net weight
