Well, I have never replaced a surround, but everyone says it is easy and it looks it. I would phone local electronic repair shops to see if they have any. Otherwise there are several available on the internet.

I have been looking at some of the speaker projects and have noticed that Fostex speakers seem to be very popular and have good results, so what improvement would I get by replacing the mid range speaker with them? And as for the tweeter I was thinking of trying Audio Note unless the Fostex could do better for both jobs but then I would have to change my equalizers right away.

I will start searching for replacement foam now that I know it is possible to purchase it.

I dropped into a home audio store today and bought two 10" speaker foam surrounds. It was allot easier to get these than I thought is would be and the guy there even said that these are good speakers, better than I remember them being, the frame is really thick aluminum.

The total cost for both foam peices was about $34, saving me a tone of money because I thought I would have to buy brand new sub speakers.

So big thank to the guys at Peak Audio for also providing some repair advice.

Cool. Let us know how you make out. Do a search before you start as there are a lot of tutorials and videos on the matter.
Cheers

The foam replacement was an easy success!!! :mrgreen: The speaker seemed to centre better than expected, and before the cone had a slight amount of scratchyness to it but now there is non at all.

The refit took a couple of hours, and the glue drying process was tricky because I had to work with the foam to prevent it from wrinkling and lifting.

I also did an crossover upgrade reusing parts that I salvaged from other speaker crossovers, I paralleled many film caps to get the exact rated values of the original electrolytics, these values were measured to be dead on in the end, but I can't conclude weather or not there is an improvement from the originals.

A friend of me who replaced foam surround occasionally said he remove the center dust cap with a knife and he would shim the coil with paper to centered the coil with the magnet. New dustcaps are available too.

I have done that before, using a piece of paper to center the coil, I think you can even purchase a better dust cone to replace the paper cones normally used on older speakers, I have two big Sony low range speakers that need to be re-coned, and I am thinking of putting them into square cabinets to use as external subwoofer speakers.
