ISP Technologies Vector 212 400W 2x12 Guitar Extension Cabinet

Add the active 400-watt Vector 212 extension cabinet and you literally double the available power of the system to 800 watts RMS. The Vector 212 speaker connects to the extension output of the Theta combo and includes the same 12-inch Celestion guitar speaker and 12 inch high excursion subwoofer for that incredible deep low-end.
