The Micro-Sub 408P is a very compact powered subwoofer designed for permanent installation. It uses four 8” low frequency drivers in a sealed enclosure and employs a 700-Watt PowerSoft Class D amplifier with on-board DSP to achieve superior transient response and maximum output. The Micro-Sub 408P complements the Innovox SLA Series of shallow profile surface-mount loudspeakers and the Flex Video Series of display-mounted loudspeakers. It also is used as a low bass component in extended range distributed audio systems.
