Open the documented service reference ↗

Check the model label, component markings, revision, polarity and dimensions where applicable before fitting. Disconnect equipment from power before inspection; internal controller repairs require a suitably qualified technician.

Service manuals & PDF downloads ↗

Match the exact version.

Use the documented part reference, electrical rating, dimensions and revision to identify the correct item. A listing for one speaker or controller generation does not establish compatibility with another.

Send the model label, old component markings and quantity needed with your enquiry. Where a source has conflicting values or a superseded reference, the listing records the uncertainty.
