i just loaded one of my boxes with 3 vintage 30's and one warehouse veteran 30 to see how it sounded under my 350L. it was quite disappointing and boring, no character. i will say that i thought they sounded better under my sound city though. i spent a good week trying different speakers in different boxes and ended up where i started with 2 old (ripped and repaired) square magnet eminences and 2 (also muffed up) cts speakers out of an old peavey cab. the combo gives me the "hollow ring" i'm looking for. i did however just pay for 4 celestion g12t100 because they were cheap and i've heard they aren't all that bad. i should have them sometime this week...
