SB Acoustics Satori WO24P / Paper

The SB Acoustics SATORI WO24P 10" (25cm) woofer with  patented Paper/Payprus membrane is available in a 4 Ohm and 8 Ohm version. The ultra-light membrane is supported by a powerful ferrite magnet  The resonance frequency of around 30 Hz is far outside the usable range, which means that the driver is extremely linear in the usable range and can be used optimally in 2-way operation or as a woofer. The generously ventilated centering spider optimizes the rear compression behavior to a maximum and provides additional cooling.

• Hard paper cone for improved piston running (own production)
  
• Large optimized motor system with undercut pole piece and double short-circuit rings
• Ventilated, aerodynamic cast aluminum chassis for optimal strength and low compression
  
• Soft rubber surround with low damping for optimal transient response
  
• Linear symmetrical suspension for improved dynamic performance
