Satori MR16PNW / Paper

Satori MR16PNW / Paper is a 6.5 inch (16.5 cm) midrange driver from SB Acoustics. The Paper/Papyrus diaphragm is based on proprietary cone material with EGYPTIAN PAPYRUS fibers. A powerful neodymium motor system with 1.17 T magnetic flux density and 0.13 kg magnet provides the drive. Available in 4 Ω and 8 Ω variants with sensitivity of 92.5 dB (4 Ω) and 88.5 dB (8 Ω) at 2.83 V/1 m. The frequency range is from 80 Hz to 3 kHz, the free air resonance Fs is at 31 Hz, and the effective diaphragm area is 119 cm². A 35.5 mm CCAW voice coil on a non-conductive fiberglass former with a 11.2 mm coil height, 5 mm air gap, and 6.2 mm linear excursion (p-p) is integrated. The ventilated, aerodynamic aluminum die-cast chassis is complemented by a ventilated pole piece and voice coil former, as well as a generously ventilated spider. Soft rubber surround, extended copper sleeve on the pole piece, silver wires with 180° spacing, mode-balanced cone, sealing and bolt hole protrusions, and a low ratio of piston to chassis diameter are implemented.
