Thanks Adam. Hope it won't be beyond me.
Shame I'm not a bit nearer Stephen, I could have given you a hand. I've done loads of speaker surrounds. If you want any tips or advice give me a shout! :)Quote:

Shackman Dynastats were my very first 'hifi' speaker - not at all bad sounding, actually.
Looks are, err, subject to personal taste. :)
the last pair I saw on ebay a couple of years ago went for £50 so it's a shame that these start at £199. :scratch:
Interesting speakers, though!
and a lovely pair of Celestion Ditton 44 with a sensible BIN http://www.ebay.co.uk/itm/Celestion-...item4ace9cbb26
I bet these sound great for under £300 :)
and some Celestion stat hybrids ...

I've never heard them, but if I was still in to my speaker boxswapping, these would defo be on the list! :)
Not stats but ribbons. They had a very good reputation at the time, I would go for them too if I was in need of some good speakers.
:doh: ribbons, of course they are!
Thanks Geoff. I really appreciate that.Quote:

Basically -
(1) Remove all traces of the old surround and clean the mounting face well with Isopropyl alcohol. Do the same with the cone but do not soak it if it is paper.
(2) using a scalpel or craft knife, cut off the old dust cap. Do this VERY carefully so as not to cut the voice coil wires
(3) Position shims between the pole piece and the inside of the voice coil to centralise it
(4) Stick surround to cone
(5) Stick surround to chassis
(6) Remove shims and stick new dust cap on.
I generally spread the task over a week of evenings, as it only takes ten minutes or so each day that way, and also ensures that the glue is dry from each step before proceeding to the next - I do (1), (2) and (3) on the first evening, (4) on the second, (5) on the third and (6) on the last.

You can centre them by eye, but if you're very fussy, you could measure down from the edge of the cone in three spaced positions and lightly pencil mark where the dust cap is to go.
Yes, I always bond new surrounds to the cone first. Use Aleene's original Tacky Glue for everything, it's the best I've found. Before bonding the surround to the chassis edge, BluTak it in several places in the position you expect it to go and check for free back and forth movement, i.e., no coil binding/rubbing. Once you're happy, then remove BluTak from three equally spaced positions and glue the surround at these points with a small dab of adhesive and let it partly dry, but not so much as to stop you pulling the surround free if need be. Recheck for free movement, if OK continue and glue the rest down. Just use a small art paintbrush. If binding, carefully pull the surround free again, you may need to slip a scalpel under to do this and start once again.
