M181Tmk2 is designed for applications in which very deep and clean bass performance is required. The 195 liter cabinet gives the unit a roll off at 37 Hz, ensuring sub-bass output below 30 Hz.

The woofer features a 5" voice coil with a linear excursion of +/- 9mm. Furthermore the woofer contains a double spider system to ensure a controlled piston movement at maximum excursion. Very high power handling and low power compression is provided by an extremely efficient cooling system. M181Tmk2 is prepared for top-hat mounting.
