The SB Acoustics Satori MR16P-4 is a high performance 6½ 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: MR16P-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 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.
