Satori MW19TX / TeXtreme

The SB Acoustics SATORI MW19TX 8" (20cm) woofer with  patented  TeXtreme membrane is available in a 4 ohm and 8 ohm version. The ultra-light and extremely stable 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 applications or as a woofer. The generously ventilated spider optimizes the rear compression behavior to a maximum and provides additional cooling.
