Hi. My Mesa Boogie Powerhouse 1x15 is dead. Speaker impedance is some milli ohm, instead of 7 or something similar (it ise the 8. Ohm version). I think the coil is gone. But in Italy a new 15" Mesa speaker is 379 euro, about 450 $ !!! What if I install a different speaker? What brand and model? What do you think about it? I really like the reaction to distorted sounds of Mesa speakers, but its reLly expensive!
