SB Acoustics Satori MR16P / Paper

The SB Acoustics SATORI MR16P 6.5" (16.5cm) woofer/midrange driver with paper/papyrus membrane is available in a 4 ohm and 8 ohm version. The ultra-light membrane is driven by a powerful neodymium drive. The resonance frequency of around 30 Hz is far outside the usable range, which means that the driver is extremely linear in the usable range and can be used optimally in 2-way use or as a woofer. The generously ventilated centering spider optimizes the rear compression behavior to a maximum and provides additional cooling.
