Amina MOBIUS DUAL Single Stereo Speaker

The MobiusDual is a single-panel stereo invisible loudspeaker, using the same OptiDrive, OptiDamping and Reduced Resonance Exciter technologies that are found in the Mobius Series Invisible Loudspeakers.
This gives high quality dual-channel reproduction where there is insufficient space for a pair of speakers.

Rendered invisible behind a 2mm skim of plaster, or other material such as solid wood, veneer or leather, it is the perfect solution for aesthetically sensitive applications where stereo image (width) is not critical but sound quality and even dispersion are still required.

Recent engineering development has resulted in improvements in key areas of audio reproduction:
  • OptiDrive technology optimally distributes the audio signal to the speaker’s exciters to ensure exceptional high frequency clarity on and off-axis. The result: improved tonal balance and treble detail. 
  • OptiDamping technology delivers increased low frequency extension and improved mid-range accuracy by selectively tuning discrete vibrational modes that are generated in the loudspeaker’s acoustic panel.

The MOBIUS DUAL is a single Stereo speaker. It requires a Mounting system and Amina Protection Units.

Amina Bass Support

ALF40 (100px wide)

Amina's compact ALF40/ALF80 Bass Enhancers are the first subwoofers Amina has designed and engineered specifically to complement Amina's current line of invisible speakers.

Because of their unique hidden design and excellent sonic performance characteristics, the ALF40 can also be incorporated into any conventional speaker system where minimal visual impact of the subwoofer is required.
