I am a fan of the fender sound. I just picked up an 80's fender 2x15 cab. "It has two ampeg 15s, for better sound" says the sales man at the store. I heard rumor that the old JBL speakers are still in production by some company in japan. Does any one know what legendary JBL speaker I am looking for? I saw the D130F on some pages. Could I be looking for a D150 though? I love lows and low mid growl. I like the cab as is, but I am looking for LOVE, and higher effiency speakers. If there are any 15" speakers I can load in this cab and get a usable 30 hz I would be oh so happy (I understand due to the laws of physics I am almost screwed with this dream of mine). Any help is appreciated.
