The SB Acoustics Satori MR13PNW-4 is a high performance 5 inch 4 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 MR13P-4 but features an undyed cone presented in it's natural finish. The colourant added to the MR13P-4 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 8 ohms: MR13PNW-8
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.
