The Satori MW19PNW-4 by SB Acoustics is a 7.5 inch 4 ohm midwoofer featuring a proprietary Papyrus / paper blended fibre cone, a high airflow cast chassis and a neodymium magnet assembly. Superb extended response with very low distortion. This unit is essentially the same as the MW19P-4 but with a natural coloured cone.
Also available in 8 ohms: MW19PNW-8.
Key Features:
- Vented aerodynamic cast aluminium chassis for optimum strength and low compression.
- Proprietary cone material with EGYPTIAN PAPYRUS™ fibres made in-house.
- Soft low damping rubber surround for optimum transient response.
- Advanced BIMAX spider for improved linearity
- Powerful optimised low distortion neodymium motor system.
- Non-conducting fibre glass voice coil former for minimum damping.
- Extended copper sleeve on pole piece for low inductance and reduced distortion.
- CCAW voice coil for reduced moving mass.
- Long life silver lead wires attached 180° apart for improved stability.
- Vented pole piece and coil former for reduced compression.
- Low piston to chassis diameter ratio.
- Gasket and bolt hole protrusions for reduced coupling to speaker cabinet.
