SB Acoustics Satori MW13 PNW / Paper

The SB Acoustics SATORI MW13 PNW 5" (13cm) 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 40 Hz is far outside the usable range, which means that the driver plays extremely linearly in the usable range and can be used optimally in 2-way use or as a woofer. The generously rear-ventilated centering spider optimizes the rear compression behavior to a maximum and provides additional cooling.
