Satori MW13TX / TeXtreme

The SB Acoustics SATORI MW13TX 5" (13cm) midwoofer with patented TExtreme membrane is available in a 4 Ohm and 8 Ohm variant. The ultra-light and extremely stable membrane is driven by a powerful neodymium motor. The resonance frequency around 40 Hz is well outside the usable range, allowing the driver to perform extremely linearly in the usable range and making it ideal for use in a 2-way setup or as a subwoofer. The generously ventilated centering spider optimizes the rear compression behavior to a maximum and provides additional cooling.
