SB Acoustics Satori WO24P / Paper

The SB Acoustics SATORI WO24P 10" (25cm) bass-midrange driver with patented Paper/Payprus cone is available in a 4 Ohm and 8 Ohm version. The ultra-light cone is driven by a powerful ferrite magnet . The resonance frequency around 30 Hz is well outside the useful range, which means that the driver plays extremely linearly in the useful range and is ideal for 2-way use or as a woofer. The generously ventilated centring spider optimizes the rear compression behaviour to a maximum and provides additional cooling.

• Hard paper cone for improved piston run (own production)
  
• Large optimized motor system with undercut pole piece and double short-circuit rings
• Ventilated, aerodynamic cast aluminum chassis for optimum strength and low compression
  
• Soft rubber surround with low damping for optimum transient response
  
• Linear symmetrical suspension for improved dynamic performance
  
• Non-conductive glass fiber voice coil former for minimal attenuation
  
• Durable silver cables offset by 180° for improved stability
  
• Ventilated pole piece for reduced compression
  
• Low ratio of piston to chassis diameter
  
• Protrusions in the seals and screw holes for reduced coupling to the speaker enclosure
