OK, so quite a few years back, I came across a pair of 4340's [or were they 4343's?] that had their 2121's repaired by an unknown 'repairer', who obviously took a few shortcuts, by using surrounds from somewhere/thing else which were oversized and so the surrounds were cut and rejoined to match the circumference of the frame, BUT, not only but also, the cones were also 'trimmed' back by about a 1/2" to accommodate!
Well, I was quite taken aback by this madness, but to find re-cones for a 2121, as everyone knows only too well, is just impossible these days let alone trying to find two of them.

I should mention, that my mate has these speakers now, and has done a wonderful job of trying to restore them, but we'd really love to find an authentic pair of kits to do these speakers the justice they deserve.
Only problem is, we're in Australia.

I'm open to recommendations....

Can anyone help? Please?

George.
