The high-power, discrete passive subwoofer that can play the loudest and lowest whilst remaining easy to install into a wall or ceiling. Using a Distributed Transmission Line design with an array of 4″ drivers, the ALF120 packs a punch while staying incredibly slim. At only 118mm thin and 345mm wide, it is designed to fit into a cavity wall or ceiling, and ports into the room via a discreet slot. The ALF120 can play down to 27Hz at 108dB at 1m from just 50W, making it perfect for high-volume applications such as media rooms and home theatres where sub-bass needs to be felt as well as heard.
