Looking for dynaudio 24w100 8ohm woofers!

Why don't you literally google it? Plenty of links.

I have looked everywhere, there discontinued. 
There is one listing on eBay in Germany but he won’t ship to Canada. 

I am guessing the the foam surrounds gave up which is to expected with Dynaudios of this vintage.. I would inquire about having the surrounds replaced, buying used will only delay the inevitable.   IN the US I can highly recommend Bill at Millersound
