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 ReducedResonance Exciter technology. This offers 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.
