SB-Acoustics 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
• High piston to chassis diameter ratio
• Gasket and bolt hole protrusions for reduced coupling to speaker cabinet
