JBL Loudspeaker Repairs

JBL Aquarius

I started restoring a pair of these speakers, replacing the foam surround I found the easier procedure to glue the outside edge first, then the edge on the speaker cone, these (surrounds) need to be specifically obtained (from the USA) for the 8in drives as the external lip is very narrow, the cabinets had been painted a shade of brown, sanded them and resprayed matt black, one of the bass drivers turned out to be o\c although continuity was measured across the terminals, there is a resistor network connected across.
