I think I know why, but was hoping I could get some opinions here. I was running a Hartke 210TP 150w 8ohm and a Hartke 115XL 200w 8ohm thru a Berhinger BX3000 300w head. We blew a PA amp so we had no monitor system live last week. So I had to really push my amp to be able to hear, it was clipping on the output side but I had to keep it up. I think because the BX3000 couldnt supply enough power, thats why it blew the speaker. But why has the 210 not had an issue and this is the second time I have blown the 115? Anyway, I think I have solved the problem by upgrading heads, I got a Gallien Krueger 1001RB-II. I ran it last night and it never clips, but the 115 speaker is not sounding good at all, but this was not due to the new head. So, once I have the speaker in the 115 replaced, do you think I will be all set? I am thinking of upgrading cabs, but money is tight right now. I would like to run this till I can afford a solid cab like a 6x10 ampeg.
