I have spent several hours over the past two days searching for size/shape compatible surrounds. The most likely candidate so far are surrounds from Simply Speakers.
The surrounds attach to the underside of the SBX500 woofer discs which is a shiny metal surface - presumably aluminum.
Two years ago I attempted surround replacement to the undrside of 5" woofers with a poly cone and those surrounds coincidently came from Simply Speakers. That attempt was not successful due to the awkwardess of accessing the underside of the cone and the clear, fast setting adhesive provided by Simply Speakers. I think that clear glue was rubber based. There was not enough time for me to position the surround on the cone before the glue got too stickey to work with. They then sent me some conventional slower setting white glue.
I expect that gluing a surround to the underside of these Technics SBX500 woofer discs will be fiddly and somewhat time consuming. My question is will the conventional white' slower setting glue bond properly with the metal surface of the disc's inderside?
The attached photos are as they are now. The residual old surround material on the disc's underside is still in place. I am debating on attempted removal by blade & scraping or trying some type of solvent.

What a coincidence! I've had a smaller variant of this model sitting around waiting for a while. I used a water based adhesive on the first unit and it worked well. I have however checked with T7000/B7000 and it doesn't seem to affect the foam, nor the honeycomb face but not that it should.
What I did do however, was to make some jigs and plastic parts to stabilise the cone so it would stay centered. I basically kept it in a chokehold between the spokes of the basket. That helped tremendously in reducing the amount of fiddling I needed to do.
