My speakers are deceased :-( Repair or replace?

[walpurgis]

How does one find out what size of foam is needed?
All I seem to be seeing is foam for bass drivers about,but its the mids on my old SMC's need refoaming and Ive a couple more sets of speakers in the garage could do with refoaming too!!
News years resolution...get them all done or give them away

It's best to buy surrounds that are specifically made to fit your cones, but failing that, the foam edge supplier should be able quote dimensions and you will need to measure the cone you intend to repair. You need the width of the foam overlap on the cone itself, the width of the roll or pleat and then the width of the area bonding to the speaker frame lip. Some cones have a lip that turns inward (like Tannoys), be sure the foam surround you intend to use can accomodate this. If your surrounds come without adhesive, I'd recommend 'Aleene's Original Tacky Glue', it's water based and easier to work with than contact adhesive, it also cleans off easily.

Most of what you need is available on eBay, you may need to check international listings though.

Many thanks to all of you for your instructions and encouragement - my AP2s have their full compliment of bass once more and I'm a happy man :-)

Of course, a part of me will always wonder whether they would have sounded even better if I'd bought the new bass drivers - especially as moving house means that so many variables have changed that I can't easily compare the old sound with the new - but the fact is that right now they sound way better than the JPW Gold Monitors I was using in the interim. I also have a great sense of satisfaction :-)

Many, many thanks!

Simon.

Well done that man!

And, no they wouldn't have sounded better with new units, simply because the cones you have are nicely run-in. New drivers would probably take months to get near to what to were used to.
