Mobius 7i

The Mobius7i incorporates OptiDamping, OptiDrive and Reduced-Resonance Exciter technology. This gives smooth high frequency extension, high power handling and improved low frequency performance.

Product Description

Building upon 20 years of R&D at the cutting edge of invisible speaker technology, the ‘i’ update to the Mobius range of loudspeakers takes the already highly-refined acoustic performance of this fully-covered loudspeaker range to new heights. With the development of brand new proprietry high frequency transducers and in combination with Amina’s patented Optidrive®, Opti-damping® and Reduced Resonance Exciter® technology, Mobius speakers continue to perform well into the ultrasonic region and now provide significantly higher sensitivity and increased low frequency extension, giving an even more open and prominent sound in the vocal range and ultimately providing even more linear performance throughout the frequency range.

Example Applications

Residential audio solutions, high power multi-channel surround sound & highend commercial installations. In-wall / ceiling with 2mm plaster skim, or into cabinetry / millwork & covered with wood, leather, slate, marble etc. Can be supplied with high-impedance 100/70V transformer.

Frequency Response


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 where Mobius loudspeakers are installed into stud walls/ceiling.

The BackboxSW345 provides a strong mechanical fixing method for solid blockwork and concrete walls/ceilings.

Single-Channel Protection

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.

Multi-Channel Protection

Both 8-channel and 16-channel passive rack-mounted protection units are available for Mobius Series 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.
