The SB Acoustics Satori MR13P-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. The cone is lightweight, rigid and has high internal damping resulting in excellent detail.
Also available in 8 ohms: MR13P-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.
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.
