Amina ALF100SM
Amina ALF100SM subwoofer designed to be recessed into a wall or ceiling, with a distributed transmission line design and minimal visual impact.
Description
The ALF100SM is a subwoofer from Amina, designed to disappear into the building structure. Installed within a partition wall or a hollow ceiling, only its vent remains visible, providing low-frequency extension without any notable visual presence in the room.
This subwoofer is based on a distributed transmission line design combined with a matrix of 4 speakers. This architecture allows it to remain particularly slim, with a thickness of just 118 mm for a width of 345 mm, while delivering a low-frequency response down to 27 Hz and a sound level of 111 dB, from a power of only 50 W. Its operation requires a suitable DSP amplifier or system processor, responsible for handling equalisation and speaker protection.
This type of subwoofer is aimed at integration installations where the room's aesthetics take priority, particularly home cinema projects or high-end multiroom sound systems where no speaker element should remain visible. It suits configurations driven by a DSP system capable of fully exploiting its low-frequency capabilities.

What to check before buying used
Check that the subwoofer comes from a recessed installation in good condition: the matrix of 4 speakers and the distributed transmission line cannot be visually inspected once mounted, and an impact or water ingress during removal could affect the suspensions without any outward sign. Also check the condition of the grille and the exposed vent, the only elements visible day to day, as well as the presence of the original connecting cables to the DSP amplifier, essential for its operation and for protecting the speakers.
