The Amina® AIW Plaster In-Wall loudspeaker series (SoundUnseen) is the world’s first high performance loudspeaker that is designed to be skimmed over
with 2mm of normal finishing plaster, providing a completely concealed audio solution whilst allowing designers and builders a very high quality
wall finish ready to accept a decoration of choice (paint, paper, textured plaster etc).
The Amina AIW3 Plaster In-Wall loudspeaker is the 40 Watt version of the range. Like the AIW1 (20 Watt version) and the AIW5 (80 Watt version) it
is based on NXT technology, and comprises a specialist lightweight yet very rugged composite panel material, the surface of which, after receiving
a 2mm skim of plaster, vibrates to generate acoustic energy. However this type of product has also been very specifically engineered to have a rigid perimeter panel
section to ensure no possibility of cracks forming in the surface plasterwork between the product and the surrounding wall structure.
How does it work?
At the heart of the Amina AIW3 Plaster In-Wall loudspeaker is its acoustic 'engine' using two of the very latest rare earth magnet, high power vibrational excitation drivers, allowing it
to handle 40W of continuous power. Generating 99dB of sound (measured 1m away), even after plaster is applied, the AIW3 has the ability to cope with the dynamic
sounds, from individual notes of the classical guitar to the giant explosions in a modern action movie.
The excitation drivers set up tiny but powerful
vibrations, (you can feel them, but you cannot see them) in the panel. These are then transferred through the plaster, paint or wallpaper that is placed on
top of it, which then excite air molecules at the surface of the wall, which in turn excite other air molecules until the sound reaches our ears.
The rigidly held perimeter of the panel means that the vibrations cannot cause cracking around the edge of the product.
Operating in the same way as natural musical instruments such as the acoustic guitar, violin or piano, these vibrations recreate sounds far more evenly and
less directional than a conventional cone based speaker. This creates a very wide area in which the surround sound or stereo sound field is heard properly,
even when seated right against the active wall.
Installation
The width of the Amina AIW3 Plaster In-Wall loudspeaker (345mm) allows it to fit well within 400mm centred wood or metal stud-work commonly used today in walls and ceilings. However,
for special cases (for example for setting in the plaster work between old wooden ceiling beams in heritage properties), narrower units can be made to order.
Please ask for details.
The Amina AIW3 Plaster In-Wall loudspeaker is supplied with fixings for easy installation into plasterboard stud walls and ceilings and for dot and dab
plasterboard faced walls. It is fixed to the plasterboard and not to any rear wall structure or studwork. These fixings are fixed with two dry wall screws
to the surrounding plasterboard, and set all the levels required to ensure the panel sits flush with the front of the plasterboard.
Alternatively you can use the Amina Plaster-In-Wall aluminium back box with acoustiblok. This is 70mm deep. The acoustiblok material prevents transmission of
sound through the wall and enhances to audio in the listening room.
In solid block, brick or concrete walls, a metal back box is available, see Amina Solid Wall back box below in compatible Products, to ease
the installation process. This is 45mm deep.
A 2 channel protection circuit (APU2) is required. This is supplied with each single or pair of speakers (product code for the speaker plus APU2 is
AIW_X). A powered sub woofer is recommended for applications requiring low bass frequencies. Ideally you should
use an amplifier or AV receiver that can balance the speakers to allow for slight variations in frequency response due to plaster depth variations.
