Description
The SB Acoustics SATORI MW19TX 8" (20cm) bass-midrange driver with patented TeXtreme cone is available in a 4 Ohm and 8 Ohm version. The ultra-light and extremely stable cone is driven by a powerful neodymium motor. The resonance frequency around 30 Hz is well outside the usable range, which means that the driver plays extremely linearly in the usable range and is ideal for 2-way use or as a woofer. The generously ventilated centring spider optimizes the rear compression behaviour to a maximum and provides additional cooling.
