Utilising a highly efficient Distributed Transmission Line design, the ALF120 is the perfect discreet subwoofer for installation into walls, ceilings or cabinetry. This passive subwoofer is capable of reproducing frequencies down to 24Hz at an incredible 111dB from just 50W, all with excellent accuracy, low group delay and minimal distortion. Only 118mm deep and porting through a slot designed to vent discreetly through an opening in the skirting board, the DTL design allows for easy installation into standard cavities while giving incredible sonic performance. In order to protect the subwoofer once installed and to help achieve accurate audio integration into the audio system, the ALF120 must be used with a DSP amplifier or separate processor.
Example Applications
ALF120 subwoofer installs straight into cavity walls, ceiling voids or furniture with a minimum cavity depth of 121mm, porting directly into the room through a slot vent which is to be cut in skirting board, ceiling or cabinetry as per installation guide. Port location may be adjusted to allow for an end-fire installation, specifically designed to allow the ALF120 to be installed flat, into furniture.
