9½″ SATORI WO24P-4 / Paper
Features
- Hard paper cone for improved piston operation (made in-house)
- Large optimized motor system with under-cut pole piece and dual shorting rings
- Vented aerodynamic cast aluminium chassis for optimum
strength and low compression - Soft low damping rubber surround for optimum transient response
- Linear symmetric suspension design for improved dynamic
performance - Non-conducting fibre glass voice coil former for minimum damping
- Long life silver lead wires attached 180° apart for improved stability
- Vented pole piece for reduced compression
- Low piston to chassis diameter ratio
- Gasket and bolt hole protrusions for reduced coupling to speaker cabinet
