Ultra-flat aluminum housing with a high-performance amplifier and a 7"x9" rectangular chassis. This subwoofer is very trendy because it fits well in tight spaces, such as under the front seats. The decisive advantage of this design is obvious: Thanks to its compact design and its high and low level inputs, this active subwoofer can be connected to any existing sound system. The ACITIVE9-SQ switches on automatically via the speaker inputs thanks to the "Auto Turn-On" function.
