I am restoring a pair of Avance Pryamide 150 concrete speaker's. Physically there are in pretty good state with just and few minor blemishes to sort.
Electrically the situation is not so great, all 4 driver's blown. But that is not really an issue as modern replacements of the originals are readily available.
The crossover's are where I need some help as one of the boards has been snapped in half. Also I'm not entirely convinced the fitted crossover's are original, as all Avance crossover's I have seen have on the net have some form of driver protection. Those fitted do not, if anyone on here has any information be it circuit diagram or pictures, it would be very much appreciated.
I have emailed Avance on a couple of occasions, but have not seen any form of response.
I hope someone can help.
