The ALF120 is the perfect discreet subwoofer for installation into walls, ceilings or cabinetry. Aimed at the high-end integrated home cinema market, the ALF120 also makes for a great addition to any Amina 2-channel system. This passive subwoofer is capable of reproducing frequencies down to 27Hz 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 rest of the system, it is critical that the ALF120 is used with a DSP amplifier or separate processor. For DSP settings please see DSP Requirements.
