Amina ALF80 Hidden Subwoofer

Designed to be installed into the fabric of the property, visible only by way of the port vent, Amina subwoofers offer smooth low frequency extension with minimal visual impact.

With bass performance that can add warmth or shake a room when needed, the range of passive subwoofers compliment the range of Amina VPT loudspeakers to help deliver a breathtaking full bandwidth experience.

Inside ALF80 The mid-range passive subwoofer that can add great depth to music, film and television whilst remaining easy to install into a ceiling or into cabinetry. Using a 4th order bandpass design, the ALF80 can play at high level and with great depth whilst only having a small circular visible vent into the room. Built in filtering and protection circuits mean that the ALF80 can be powered from a 150W amplifier delivering full-bandwidth content. Amina Tip: ALF80 and ALF40 subwoofers have built in protection and filtering meaning that a full-bandwidth amplified signal can be supplied to the subwoofer, allowing it to perfectly integrate with Amina VPT panel loudspeakers. Installation - ALF80 can be mounted directly to stud frame using the supplied metal mounting L-brackets. Port tube can be relocated to one of 3 port-opening positions and can have it’s length adjusted to perfectly match the depth of the ceiling void (maximum adjustment 100mm). Note: Port tube can be adjusted, but should never be replaced, bent, extended or blocked. Doing so will impact the performance of the subwoofer. Amplification - Being a passive unit, the ALF80 requires external amplification. Given that both protection and filtering are both built in to the subwoofer itself, the unit can be powered by a 150W amplifier delivering full-bandwidth content. The ALF80 can be powered by its own dedicated amplifier channel, alternatively it may be wired in parallel to a single Amina VPT loudspeaker panel. Note: Please take care to match total impedance load to the amplifier when wiring subwoofers and speakers in parallel. It is not wise to wire two subwoofers in parallel to each other, however it is possible to wire a 4 Ohm subwoofer in parallel to a 4 Ohm loudspeaker panel without affecting overall load that the amplifier will see. For example, the ALF80 can be wired in parallel to a Mobius5 and still appear as a 4 Ohm total load.
