MINIATURE INVISIBLE LOUDSPEAKER
Whether you love movies or music, experience true freedom of immersive sound with the neo3 invisible loudspeaker. Installed into your ceiling or wall and covered with plaster and paint, the speaker becomes fully hidden, with great sound performance.
The smallest invisible loudspeaker available, incredible sound with no visual impact.
Using Surface Sound Technology™, Neostein neo3 generates sound through micro vibrations in the surface of the wall or ceiling.
SST gives not only great sound but an incredible listening experience unlike any conventional loudspeaker. With true 360º dispersion, hear great sound no matter where you are in the room.
made for sound,
built to last
Becoming part of the fabric of your home, neo3 is built to last. Using standardised construction techniques, the loudspeaker is easy to install and can be covered with a 2-3mm layer of standard plaster and paint.
With an in-built plastering guide, and protection circuitry, you can be sure that the speaker is installed correctly and lasts for years to come.

Ensure there are no other services in close proximity to the loudspeaker (including high or low voltage power cabling, pipes, ducting or similar).
Pre-run loudspeaker cable to the speaker position. Neostein recommends using double-insulated stranded cable with a maximum thickness of 8GA (3.5mm core). 12GA-14GA recommended for ease of install. It is not recommended to wire Neostein loudspeakers in series or parallel
Take this opportunity to inspect the ceiling/wall construction to make sure nothing is loose as this may rattle and vibrate once the loudspeaker is installed. Any loose debris should be removed from the ceiling/wall.
Insulation may also help to slightly reduce the chance of sound transference into adjacent spaces, however it is unlikely to offer complete sound isolation. Further steps may be taken to reduce sound transfer, for more information speak to your Neostein distributor.
Neostein recommends using additional drywall screws to secure the board in the location of the speaker. This helps to ensure a more rigid bond between the board and the framework, reducing the likelihood of rattles or buzzes once the speaker is installed.
It is critical that the rear of the ceiling board is kept clean and free from debris, resting cables, spare screws or other loose material that may rattle or buzz once the speaker is installed. All cabling should be tied up off the surface of the ceiling, using soft insulation material around the speaker is also recommended.
Neostein recommends cutting a small inspection hole prior to cutting the full speaker hole. This should be big enough to insert a tape measure or your hand into the ceiling void to make sure the speaker hole is centred between the studs and will not conflict with any existing services.
Once it is safe to proceed, mark and cut the hole in the ceiling board for the speaker. For Neo3 loudspeaker, you should cut a hole that is approximately 214mm x 304mm and not any larger than 218mm x 308mm. You should be left with a hole that is neat and tidy, with no loose debris that is approximately 2mm larger than the loudspeaker (gap around the speaker should be no more than 4mm). Clear any loose or chipped plasterboard from the opening and clean any debris from inside the ceiling cavity.
Screw the mounting strips securely to the rear of the plasterboard using 2 screws per strip. Make sure screw positions do not conflict with the speaker tab position (space screws approximately 50mm/2" apart).
The plywood mounting strips give a solid material for the loudspeaker to be screwed into. If your ceiling construction includes plywood/OSB backing boards, it may not be essential to use the mounting strips. The loudspeaker should not be screwed to the plasterboard alone as the screws will have no material to bite into.
If mounting strips are misplaced or damaged prior to installation, strips of OSB/plywood or timber batons may be used in their place. The mounting strips do not need to be attached to the ceiling framework.
If the loudspeaker is being retrofit, fish the new cable through the ceiling cavity to the loudspeaker location.
Try to minimise the amount of excess cable. If you do have a spare length, either cut it shorter, or tie it up out of the way of the speaker so it does not rest on the rear of the plasterboard.
Strip no more than 10mm of the cable core to reduce the likelihood of an accidental short circuit. Make sure there are no splayed out stray strands of the cable core as these are more likely to cause short circuits if not contained within the terminal once the speaker is connected.
Connect the loudspeaker to the cable, paying attention to the cable polarity. Ensure all speakers are connected with correct polarity. Connect the black-sheathed core to the black terminal (negative) and the red-sheathed core to the red terminal (positive). If your cable has different colour cores, ensure all speakers are connected in the same way throughout the entire system.
As the screws tighten, the loudspeaker tabs should bite into the plasterboard surface, slightly recessing into the paper. The surface of the loudspeaker should now be flush with the surface of the plasterboard (or ever so slightly proud).
The loudspeaker should be centred in the hole, with a consistent gap surrounding the entire speaker.
Once the loudspeaker has passed the test stage, use a low-shrinkage joint compound to fill the gap between the loudspeaker and the ceiling board. If the gap is greater than 4mm in width, you may need to fill the hole in several stages, letting it fully dry between each application.
Neostein recommends using British Gypsum Gyproc-joint-filler or similar suitable jointing compound.
Edge fill should be fully dry before proceeding to the next stage. This may need to be left over night.
The mesh scrim can be applied as strips, as long as the entire surface is covered. The tape can be pressed into wet joint compound, however Neostein recommends applying it immediately prior to final plaster work taking place.
Mesh scrim tape helps to strengthen the plaster in the location of the speaker, meaning that the plaster will not crack once the loudspeaker is played. The scrim tape also helps the plaster to remain fully adhered to the loudspeaker panel.
Plasterboard primer or sizing should not be applied to the loudspeaker surface.
If entire ceiling/wall is to receive a full wet skim-coat of plaster, the loudspeaker can be covered at the same time. The plaster thickness should not exceed 2mm.
The loudspeaker uses a plaster guide on the panel which should sit just under the finished plaster level. Excessively thick plaster may reduce the loudspeaker sensitivity and affect its tonal response.
High-pressure plaster application such as polished plaster is not recommended, however it is possible with care. Please contact your Neostein distributor for more information.
For other plaster variations such as patch plastering (dryline installation) please consult the full installation guide.
The finished surface can now be painted or decorated in the same way as it normally would be.
Loudspeaker should not be covered with tiling or other rigid/heavy finishing material, however can be wallpapered over.
Please ensure all trades are now aware that an invisible loudspeaker has been installed in the ceiling in this location.
Once paint is fully dry and all light fittings have been secured, it is recommended to re-test the loudspeaker, paying attention to light fittings, sensors and other ceiling furniture. If any rattles are heard, ensure the fittings are all tight and secure. Your invisible sound system is now ready to be connected and enjoyed.
