Amina ALF40 Passive Subwoofer
Amina's ALF40 Bass Enhancer

Amina's compact ALF40 Bass Enhancer is the first subwoofer Amina has designed and engineered specifically to complement Amina's line of invisible speakers.

Because of its unique hidden design and formidable sonic performance characteristics, the ALF40 can also be incorporated into any conventional speaker system where minimal visual impact of the subwoofer is a requirement.

The ALF40 Bass Enhancer has been designed to compliment both AIWX and iQ Series invisible loudspeakers.

Utilizing a 43mm convertible ported design, the ALF40 easily blends into any room environment by mounting within ceilings, floors, or even furniture, taking zero room from the living spaces.

It provides additional low frequency support and extension and integrates easily in audio installations by virtue of it being extremely small and able to connect in parallel with the main speakers.
The unique port design provides the necessary acoustic filtering to blend with the main speakers and also allows adjustment to suit a variety of install locations – be it in-wall, in-ceiling or free-standing.

Measuring just 360mm x 135mm x 160mm and weighing less than 3kg, this passive 40 watt subwoofer can deliver 103 dB SPL/1m with frequency response down to 60 Hz.

This makes the ALF40 the perfect hidden bass enhancer for low to mid-power applications.


The ALF40 is supplied with a complete mounting which includes multiple brackets and a port extension tube enabling installation in floors and ceilings.

Amina ALF40 Subwoofer Warranty:  *5 year manufacturer limited warranty for residential applications.

ALF40 Ceiling mounted (edit)

* Amina subwoofers are guaranteed for 5-years when installed by a trained, approved professional!

Amina ALF40 Subwoofer - complements perfectly any discrete or invisible loudspeakers custom installation.
