If your crossovers are still working correctly, and all you need is a refoam, you can refoam them yourself. There are companies both in the US and UK that sell refoaming kits. I only needed to do the midranges on mine. Once you get the covers off, the four speakers come out as a unit with their plastic surround by removing a few screws. Take lots of photos before you remove the wiring so that you can make sure to get it back together correctly. That or put labels on each wire. Or both. 🙂
Refoaming is a bit of a PIA, but mostly it is just time consuming. You need to remove all the foam and glue residue from the cone and the frame. The kit I got had detailed instructions.
Since I’m not in the UK, I cannot really recommend someone to do it for you. I imagine there is a reputable specialist in your area. It will be far less expensive to ship the speakers without the cabinets, unless you can deliver to a local shop. Good luck.
