Yesterday I ran a 70's Traynor 50 watt head into my 2x12 Greenback cabinet... the more I turned it up the BETTER is sounded - LOL! POP! Thin & scratchy sounds now!!! (they were bought new, 90's era replacement speakers, not sure if still made in UK back then) Anyway, can you recommend a good recone company? I was wondering if you can up the power rating when doing so. Thanks!!!! - I'm in Southern Cal area.
