Our flagship plaster-over series.

An Amina speaker

Rendered invisible behind a 2mm skim of plaster, the Amina Mobius7 invisible loudspeaker pushes the sonic boundaries of what is possible with plaster-over loudspeaker technology. Building on the award-winning Evolution Series design, the Mobius7 incorporates OptiDrive and OptiDamping technology as well as Reduced-Resonance Exciter technology, offering greater low frequency extension and smooth high frequency dispersion all the way to the ultrasonic region. These developments allow for unprecedented high frequency performance and detail, enhanced bass reproduction and increased power handling, all in the easy to install, lightweight form-factor that Amina is known for.

Support Products

Amina has designed support products to maximise the performance and longevity of every speaker. Our range of backboxes and Protection Units will match the requirements of any audio setup.

The Backbox CV345 creates an acoustically tuned and consistent cavity behind the speaker, helping to ensure both consistent audio quality as well as minimising rearward airborne sound transmission.

16-channel passive rack-mounted protection unit for Amina Invisible Loudspeakers. For use in installations with higher numbers of low-impedance speakers with a centralised AV rack. Direct-to-PCB screw terminal-blocks allow for fast and easy permanent installation.

All new slim-line design, giving reliable speaker protection for life-time worry free performance, in a unit that can be conveniently dressed back with any cable management system or sit neatly behind the rack.
