Low distortion high performance woofer:
The Satori WO24P-4 is a high performance 9.5 inch 4 ohm woofer bass loudspeaker drive unit from the flagship Satori range by SB Acoustics. Features include a hard paper / pulp cone, an aerodynamic low compression high airflow cast aluminium chassis and a large motor system with twin faraday shorting rings.
Also available in 8 ohms: WO24P-8.
Key Features:
- Hard paper cone for improved piston operation (made in-house).
- Large optimised 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.
