it seems most people prefer the stock Eminence 1058 speaker in it. I was looking for a little more highs, but it was nice. I like the 1058 alot better than the 1258. The 1028k sounds surprisingly good in this 1x10 application as well. I've used an old reconed Jensen C10Q, great highs, not so much lows. reconed P10N type in it now, nice lows, would like more highs. Had used a weber 10A125, which was nice. Had also tried a Weber 10A150T which was real nice, but made the amp way too loud, no longer a small gig amp with natural breakup. I might have to stop my tendancy for noodling, and just put the 1058 back in and call it a day. Anyone use any 10" speakers that you think work very well in this amp?
