DESC: The RIOT series features a "Tri-metal" design for strength as well as a stunning visual presentation. Multiple plexi windows show off the internal circuit topology and high performance electronic components. Built-in electronic crossovers allow for sound quality tweaking, Bass Boost (you know what that's for), and MOFSET power supplies provide excellent response and durability. RIOT amps are equipped with a remote subwoofer level control for your convenience. Above the roar of the crowd you will BE HEARD.
