Amina ALF120 Passive Subwoofer
AMINA ALF120 Subwoofer

The ALF120 subwoofer uses a unique Distributed Transmission Line bass loading technique to produce deep and loud low frequencies from a slim, in wall enclosure.

The ALF120 has been developed specifically for use in discreet, high performance, stereo and multi-channel cinema systems.

Amina's ALF120 High Performance Subwoofer

Utilising a highly efficient DTL (Distributed Transmission Line) design, 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.


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 ‘endfire’ installation, specifically designed to allow the ALF120 to be installed flat, into furniture.

Please note that warranty is void if ALF120 is not used with required DSP settings.

Amina ALF120 Subwoofer Warranty:  *5 year manufacturer limited warranty for residential applications.
