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.

Now you can put them back into the cabinets and enjoy your speakers once more
