Finish Options
Design Flexibility
Engineered to work with the covering material, Mobius loudspeakers can be installed into a number of different materials or with a variety of finish options.
Whether installed behind wood, leather, natural stone veneer or other high quality laminates or into a solid blockwork, a wet plaster skim or even a specialist finish such as acoustic or polished plaster, Mobius loudspeakers provide ultimate installation flexibility.
Explore some of the many design available options below.

Wood
Whether the design calls for natural wooden panelling or manufactured board, Amina Mobius speakers can easily be installed into wooden structures.
The speaker should be covered with 2-3mm of wood, meaning that sheet stock should be machined down to this thickness of material. For veneer applications, it may be more suitable to construct a ‘frame’ using the mounting board, with the speaker applied directly to the rear of the veneer.
Mobius loudspeakers should be adhered directly to the wood using a 2-part epoxy, giving an extremely robust and high performance installation.
For more information on wood installation, please consult the wood installation guide.
Example applications
Built into furniture, historic wooden panelling, conference room table, media wall

Leather
Whether an entire wall is to be finished with leather-wrapped panels, or a small leather accent feature is to be used, Amina Mobius loudspeakers can be installed behind both natural and synthetic leather.
Thin and lightweight leathers should be laminated onto a wooden board using a suitable contact adhesive. The wooden board should be machined to a thickness of 1-2mm in the location of the loudspeaker itself, providing adequate support for the leather.
Thick or heavier leathers may also need to be mounted to a board, however may have the loudspeaker adhered directly to the rear of the leather.
Example applications
Leather-wrapped headboard, leather-wrapped paneling, ceiling panels

Wet plaster skim
Where a full wet skim is required to cover a loudspeaker, Mobius can be installed and finished with a 2mm covering of plaster.
With options for either cavity (wall and ceiling) or solid blockwork installation, Mobius loudspeakers have been voiced for a 2mm covering of standard multi-finish plaster, however they can work with a range of alternative or specialist plaster finishes.
Finishes such as polished plaster, acoustic plaster, joint compound, plaster of Paris, glass reinforced plaster (GRP) and other traditional plaster finishes (lath and plaster, lime plaster, waterproof sculpted plaster etc) can also be used. Plastered surfaces may be finished with paint and wallpaper.
Please note that some plaster finishes may require an adjusted installation method. Please contact your distributor for more information if required.
Example applications
Cavity and solid walls/ceilings, painted, wallpaper and other decorative finishes including gold leaf.

Stone Veneer
Whether a natural or synthetic stone veneer is to be used, Mobius loudspeakers may be adhered directly to the rear of a 1-3mm veneer.
With incredible advancements in stone veneer technology, thin veneers of natural stone such as slate, sandstone, marble or cast materials such as concrete veneers can be applied to backing sheets to allow easy integration into a range of designs.
Some synthetic stone materials such as Corian® may be milled down to the desired thickness in the location of the speaker.
Please contact your distributor for more information on how to integrate Mobius speakers with a stone veneer.
Example applications
Full wall covering, feature wall, media board, furniture or design accent.

Fabric
Whether fabric is being adhered directly to a plastered wall or ceiling, being wrapped onto paneling or being stretched onto a frame, Mobius loudspeakers can be easily integrated, allowing for uninterrupted design with a tactile finish.
Acoustically transparent materials can be used in-front of a loudspeaker, but will not require direct adhesion. Non-transparent materials may require direct adhesion to the loudspeaker. Depending on the fabric properties and construction design, Mobius loudspeakers are commonly installed into wooden paneling and are then wrapped in fabric. For more information on fabric installation, please contact your Amina distributor.
Example applications
Fabric wrapped media walls, headboards, fabric wall panels, stretched fabric ceilings, projector screens
