I think I can help you to a set of 8" AR woofers, but you can also look on ebay.de .
Has anybody the right type-no's of these woofers
They need new surrounds, but this can easily be done, it is very easy to align them properly when you put a 20-100Hz signal (from youtube) on the drivers, I did glueing with bison-tix, but any tixotropic glue will work, regards Jurgen Prinsen weldtech@online.nl
