Most freestanding subwoofers are active, meaning they have a built-in amplifier, whereas in-wall, in-ceiling, outdoor, and some freestanding subwoofers are passive and therefore require external amplification. Since an AV receiver never powers a subwoofer directly, it is necessary to have additional amplification for passive subwoofers.
These subwoofer amplifiers can drive single or dual subwoofer drivers. We also have a range of packages which combine amp and driver for a complete in-wall or in-ceiling subwoofer package. Perfect for ultra discreet home cinema and music systems.
