Product Description
The entry-level passive bass-enhancer that can add warmth to music and television whilst remaining easy to install into a ceiling or into cabinetry.
Using a 4th order bandpass design, the ALF40 can play at medium level whilst only having a small circular visible vent into the room.
Built in filtering and protection circuits mean that the ALF40 can be powered from a 60W amplifier delivering full-bandwidth content.
Being a passive unit, the ALF40 requires external amplification. Given that both protection and filtering are both built in to the subwoofer itself, the unit can be powered by a 60W amplifier delivering full-bandwidth content. The ALF40 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 an 8 Ohm subwoofer in parallel to an 8 Ohm loudspeaker panel without affecting overall load that the amplifier will see. For example, the ALF40 can be wired in parallel to an iQ3 and still appear as an 8 Ohm total load.
