ALF40

Design Story

ALF40 was engineered to add real low-frequency weight where traditional subwoofers can’t go, using a tunable port tube that can vent directly into the room for stronger, more efficient bass performance. Supplied with metal brackets for stud/joist mounting and designed for cavity installs with as little as 134 mm depth, it also disappears neatly behind kickboards, under furniture, or inside cabinets. When paired with Amina invisible loudspeakers, it connects straight to a dedicated full-range amp output with no additional filtering required—keeping system design simple and invisible.
