The Amina ALF40 is an entry-level Passive Bass Enhancer, creatively designed and engineered to complement Amina’s line of Invisible Loudspeakers. Due to its unique structure and exceptional sonic performance, this product can also be incorporated into any conventional Loudspeaker System where minimal visual impact of the subwoofer is required.
Utilising a 4th order bandpass design, the ALF40 can play at medium level, despite only having a small circular visible vent. Built-in filtering and protection circuitry allows for the ALF40 to be powered from a 60W Amplifier – therefore delivering full bandwidth content.
