The SB Acoustics Satori MR16PNW-8 is a high performance 6½ inch 8 ohm midrange loudspeaker drive unit featuring a unique composite cone made of paper and Egyptian Papyrus™ fibres. This drive unit is essentially the same as the MR16P-8 but features an undyed cone presented in it's natural finish. The colourant added to the MR16P-8 adds a touch of damping at the upper frequency extreme as can be seen if you carefully compare the frequency response graphs.
Also available in 4 ohms: MR16PNW-4
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 optimized 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.
- Long life silver lead wires attached 180° apart for improved stability.
- Vented pole piece and coil former for reduced compression.
- Gasket and bolt hole protrusions for reduced coupling to speaker cabinet.
- CCAW voice coil for reduced moving mass.
- Mode balanced cone for reduced break-up.
