SB Acoustics Satori MW13 P / Paper

The SB Acoustics SATORI SATORI MW13 P 5" (13cm) woofer 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 around 40 Hz is far outside the usable range, making the driver extremely plays linearly and is ideal for 2-way use or as a woofer. The generously ventilated spider optimizes the rear compression behavior to a maximum and provides additional cooling.
