A while back I asked about Eminence replacement speakers for a '79 vibrolux & Mr. 2x6L6 linked to a nice helpful chart he made up. I went with copperheads & wanted to just share my initial experience. First of all, the original oxford speakers sounded surpisingly great at low volume, but did break up early & lacked volume. When I first put the copperheads in, I spent a bunch of time comparing the amp to my '71 deluxe Reverb w/ Reverend alltone speaker. The DR had more sparkle, the vibrolux now sounded a little midrangey with less sparkle but had a fuller sound & did sound pretty good. Played on it a little while at home loud as I could, and played a gig with it, sounded nice & strong at the gig. Then I compared it to the DR again and folks, speaker break in is no myth. A lot of the boxy midrangeyness was gone. The DR still has a little bit more sparkle & a little less midrange (& less bass) but they now sound very similar. I should say I play telecaster in a rockabilly/ country band & play clean, getting just a bit of OD from the amp sometimes. The copperheads get me my twangy fendery tele sound & the they definitely gave the amp more volume. There is more midrange than a typical vintage speaker in an old fender, but it doesn't sound cardboardy or celestion-y (sorry, celestion guys). And they don't fart out on the low E. The original oxfords I think were still best at bedroom levels, but to gig with the copperheads make the amp more useable. And they were $46 each. Webers I'm sure are more vintage correct but they're almost double the price.
