The SB Acoustics SATORI MW19P 8" (20cm) woofer with patented paper/paper diaphragm is available in a 4 ohm and 8 ohm version. The ultra-light diaphragm is driven by a powerful neodymium drive. 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 use or as a woofer. The generously ventilated spider optimizes the rear compression behavior to a maximum and provides additional cooling.
Features:
- Ventilated, aerodynamic cast aluminum chassis for optimal strength and low compression
- Proprietary cone material with EGYPTIAN PAPYRUS™ fibers from our own production
- Soft rubber surround with low damping for optimal transient response
- Advanced BIMAX spider for improved linearity
- Powerful, optimized neodymium motor system with low distortion
- Non-conductive glass fiber voice coil former for minimal damping
- Extended copper sleeve on the pole piece for low inductance and lower distortion
- CCAW voice coil for reduced moving mass
- Durable silver wires with 180° spacing for improved stability
- Ventilated pole piece for reduced compression
- Low piston to chassis diameter ratio
- Protrusions in the gasket and screw holes for reduced coupling with the loudspeaker enclosure
