Automated house 2.0 – #25 Amina unnoticeable In-Wall speakers – part 1

We wished to preserve the clean lines in our open plan barn however likewise have excellent noise too. The floor standing speakers from our last home weren’t an choice then, however was there still a method to get the audio we desired in the room?

We talked it over with our wise house partners on the project, epitome Living as well as they suggested we take a look at the Amina variety of ‘invisible’ speakers.

Fitting the Speakers

We went with a pair of these Amina Mobius5i units. These are high high quality in-wall drivers, produced in Cambridgeshire. They get plastered over as well as so totally vanish when installed. The 5i is a 450mm x 345mm x 33mm system as well as utilizes a proprietary high frequency 4 Ohm transducer.

The Mobius5i integrates OptiDamping, OptiDrive as well as Reduced-Resonance Exciter innovation to provide the smooth high frequency extension as well as low frequency performance, with medium power-handling capabilities.

We sited these in our vaulted ceiling, covering the kitchen area as well as dining area of the barn. Installing them needed cautious planning as well as coordination of trades during very first repair by epitome Living

They requirement a minimum cavity depth of 75mm as well as when the plasterboard is cut the next step is to set up their ‘BackboxCV300’ customized enclosures. These slide into the space as well as are fixed in location with screws.

The speakers were then linked up as well as evaluated with frequency generator sweep. This is to inspect there are no rattles in the walls, from something like a washer or other debris left behind the plaster board for example.

Once this test was completed joint filler was added around the edge as well as enabled to dry. then scrim tape was used before they were lastly covered over with just 2mm of plaster. The speakers replace a piece of plasterboard as well as are lightweight so won’t evaluate down the board, plus the vibrations are so little so they ought to never fracture the plaster.

Finally, the APUi50 in-line security modules were installed back at the amplifier in our rack. They function a High Pass Filter (HPF) as well as self-resetting thermal fuse to avoid damage in the event of excess present delivery.


So right here they are (or aren’t) in all their glory. As you can see when the process is completed there truly is nothing to see. Perfect.

Next Time

The Mobius5i chauffeurs get down to around 75 Hz so for a full frequency variety you requirement to add a sub. In part 2 we’ll do just that with a look at our book subwoofer installation as we lastly get to hear exactly how the whole system sounds.
