Seas 11-FM speaker repair / replacement

SEAS 11-FM Speaker Foam Surround Repair

I bought a SEAS 603 kit many years ago and over the years it has been put into new cabinets , the tweeter and woofer have been replaced so only the midrange unit 11-FM is the original. This unit is not looking so good – the foam surround has perished in places and is looking yucky :-

A search for a suitable replacement did not yield any satisfactory results – most speaker units these days are designed for 2 way systems and the 11-FM comes with it’s own sealed enclosure  cone and the specs are quite unusual. So my search turned to replacement foam surrounds – I found a company Good HIFi that offers replacement foam surrounds for the SEAS 11-FM and they also ship world wide. They have a useful video on their site showing how to replace a foam surround. I ordered 2 replacement foam surrounds an a bottle of glue. The replacements arrived and they looked like :-

Once removed from the cabinet the old foam surround is removed – useful tools are a craft knife and a wood chisel.

Next you glue the inner edge of the replacement foam surround to the cone and use a suitable weight to hold down the cone until the glue dries – make sure the cone is still centred and does  not rub on anything.

Next glue thr outer edge of the replacement foam surround to the speaker chassis – use some clothes pegs and cardboard  to hold it down while the glue dries. Once complete it will look as good as new.
