Ok, so I'm not too tech savy so I'm turning to you guys. I blew the speaker in my Hartke TP115 (150w @ 8ohms). I desperately need to replace it within a matter of days. Looking at eminence speakers and they seem to fit the bill. My questions are: Can I replace use a speaker with the same impedance but higher wattage (so I don't blow it again)? Is the replacement going to be easy, straight forward, plug and play or am I going to need to solder, etc? I suppose that's it. Need help ASAP. Thanks!
