Product Description
The 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.
Requiring a DSP amplifier (or suitable system processor), the ALF120 can play down to 27Hz at 111dB at 1m from just 50W. This makes the subwoofer perfect for great music systems but also media rooms and home theatres.
Being a passive subwoofer, the ALF120 requires external amplification, however due to the Distributed Transmission Line design using 4″ drivers, it requires DSP to maximise performance and ensure it continues to perform for a lifetime.
Either requiring a dedicated DSP amplifier or a system processor and ‘dumb’ amplifier combination, the requirement is for 3 bands of parametric EQ, 48dB/Octave bandpass filtering and absolute voltage limiting. For information on a suitable amplifier or processor, please contact your distributor.
Note:
Failure to use adequate DSP protection may result in warranty becoming void.
