Hi im looking at buying an ashdown abm 300 15 combo off ebay but the model number on the back of the head says: ABM C210T - 300 . The 210 suggests to me that it should have two 10 inch speakers not 1 15. Does this mean someones swapped the head or the combo could be dodgy or do all these combos have that model number? I've asked ashdown who agree its odd but theyre unable to check until tuesday when its to late. So does anyone have this amp and know or just know from experience? Thanks
