Call 0191 6916691 for Price


The Amina Mobius3i is a single-channel Invisible Loudspeaker, offering a smaller alternative to the Mobius5i and Mobius7i for use when there is limited stud/joist spacing. This product can also be used to supplement additional items – providing a cost-effective solution.

When it comes to state-of-the-art products, the Mobius Series takes the cake, now featuring their very own ‘i’ version; granting significant acoustic upgrades alongside high frequency transducers and increased speaker sensitivity.

Rendered invisible behind a 2mm skim of plaster or other material, such as: plaster, solid wood or synthetic veneer, the Mobius3i is the perfect solution for aesthetically sensitive applications. Uses the same OptiDrive® and OptiDamping® that is present in all of Amina’s Invisible Loudspeakers.

Product Features:

  • Hassle-free install into gib board walls or ceilings
  • Ability to skim over with a finishing coat of plaster
  • Completely invisible, high-performance loudspeaker
  • Suitable for mid/high power multi-channel Surround Sound
  • Features new technologies providing superior mid-range and treble quality
