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 ALF120
The passive subwoofer that can play the loudest and lowest whilst remaining easy to install into a wall or ceiling.
Using a Distributed Transmission Line design using an array of 4″ drivers, the ALF120 packs a punch whilst staying incredibly slim. At only 118mm thin and 345mm wide, it is designed to fit into a cavity wall or ceiling.
Requiring a DSP amplifier (or suitable system processor), the ALF120 can play down to 27Hz at 111dB at 1m from just 50W. This makes the subwoofer perfect for great music systems but also media rooms and home theatres.
Amina Tip:
Whilst subwoofers and bass enhancers have been designed to fit into a wall or ceiling, another great installation option is to build them into cabinetry or even have them sat in-room. A subwoofer could port through kick-boards in a kitchen, or from under a sofa or bed. As long as airflow is not impeded, the subwoofer vent can be easily disguised.
Installation -
Designed to be fitted into a cavity wall with 16″ spaced studs (on centre), the ALF120 is mounted using felt pads which not only hold it securely in place, but also mechanically decouple the cabinet from the structure of the property, allowing all sound energy to be effortlessly ported directly into the room and not into the rest of the structure.
It is also possible to install into a ceiling void or into furniture if this helps to further remove the slotted vent from the eye-line of the listener.
Amplification -
Being a passive subwoofer, the ALF120 requires external amplification, however due to the Distributed Transmission Line design using 4″ drivers, it requires DSP to maximise performance and ensure it continues to perform for a lifetime.
Either requiring a dedicated DSP amplifier or a system processor and ‘dumb’ amplifier combination, the requirement is for 3 bands of parametric EQ, 48dB/Octave bandpass filtering and absolute voltage limiting. For information on a suitable amplifier or processor, please contact your distributor.
Note:
Failure to use adequate DSP protection may result in warranty becoming void.
