Amina ALF80 Passive Subwoofer
Amina's ALF80 Bass Enhancer

Amina's compact ALF80 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 ALF80 can also be incorporated into any conventional speaker system where minimal visual impact of the subwoofer is a requirement.

Amina ALF80 Bass Enhancer Passive Subwoofer - is a passive, ported band-pass subwoofer for use with Amina Invisible loudspeaker ranges.

The unique adjustable port design allows the subwoofer to be installed within ceiling voids and furniture or located discretely in a free standing location.
Its 150W continuous power handling and wide bandwidth make it suitable for high power 2 channel systems and small room home cinema. Tight, tuneful and powerful bass response is ensured along with seamless integration both visually and sonically.

Utilising a unique adjustable ported design, the ALF80 Subwoofer easily blends into any room environment by mounting within ceilings, furniture or in voids formed behind stud wall sections. This creates minimal to zero visual impact.

Measuring just 605 x 270 x 156mm and weighing around 9kg, this passive 150watt subwoofer can deliver 108dB SPL/1m with frequency response down to 36Hz making the ALF80 the perfect hidden Subwoofer for home cinema and other high loudness applications.

The ALF80 is designed to be connected directly to a dedicated full range amplifier output. No additional filtering is required when used in conjunction with Amina Invisible Loudspeakers. Parallel connection with a single Amina loudspeaker is also possible.


The ALF80 is supplied with a complete mounting which includes multiple brackets and a port extension tube enabling installation in floors and ceilings.

Amina ALF80 Subwoofer Warranty:  *5 year manufacturer limited warranty for residential applications.
