01
Inspect & diagnose
We inspect the driver, coil, cone, spider, surround, magnet gap, and terminals before recommending the repair.
Loudspeaker repair
Voice coil replacement
Restore a damaged loudspeaker with careful diagnosis, correct voice-coil matching, precise alignment, and thorough bench testing by our experienced team in Mauritius.
Precision parts. Careful alignment. Reliable performance.
Our process
A complete replacement, not a shortcut
Every loudspeaker is inspected individually. The final repair depends on the driver condition and the availability of a correctly matched replacement coil.
02
Match the voice coil
The replacement is selected to suit the speaker's diameter, winding height, impedance, former, and power requirements.
03
Fit & align
The magnetic gap is cleaned and the new coil is centred carefully with the cone and suspension components.
04
Test performance
The repaired loudspeaker is checked for free movement, correct resistance, clean sound, and stable operation.
