Thanks for the reply,
had a look and its got 86 447 04 on it however getting nothing via google, ebay etc. Och well. Will see if i can find an Ampeg vendor somewhere. Didnt think it would be difficult but starting to think it may be...
Are there any alternative speakers? Other brands with similar specs you could suggest? Seen some posts talking about Eminence Legend BP102-4's but i guess if i do that ill have to replace all 4 speakers in the cab?
