SB ACOUSTICS SATORI WO24P-4 9.5” 4ohm Ferrite WOOFER Loudspeaker

SB ACOUSTICS SATORI WO24P-4 9.5” 4ohm Ferrite WOOFER Loudspeaker

Product Description:

SB ACOUSTICS SATORI WO24P-4 9.5” 4ohm Ferrite WOOFER
The Satori range was founded to separate more expensive projects from a wider range of more affordable – but still high-end – SB Acoustics products.
“As we get more experience, new materials, better simulation tools, we believe in benefiting the customer with those improvements.
We always knew that geometry is essential and we are working more and more with geometry.
Every time we get new materials, like beryllium, and we optimize the designs, there’s always room for improvement.
We’ve been able to implement significant improvements with beryllium, and we could obtain pretty good results in combination with geometry.”

Key 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 aluminum 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 fibrer 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
