I have a cabinet that is a little older and has been through many gigs in the past and has been driven fairly hard. I was thinking about buying a replacement for it but wanted to see if anyone could help with what speakers could bring it back to life. It seems to have lost it's zip and is pretty muddy sounding. Here are the exact specs. Speakers EC-1060F Cast Frame Tweeters E-2700 Cast Bell Crossover 3.5KHz @ 18dB Power Handling 540W RMS Frequency Response 80Hz - 14KHz Sensitivity 105dB SPL Impedance 4-8Ω Dimensions 23w x 23h x 18.5d Weight 90 LBS I have the 8ohm model. I've read many posts about how you can't just slap any replacement in and expect good results. I also thought putting in Neo speakers could reduce the weight a little but don't know if the cabinet needs to be built for Neo speakers. A side question would be can I make it a 4ohm cabinet by replacing the speakers or is there more to it than that. Any ideas would be greatly appreciated. I tend to prefer a more modern crisp sound than an older school mellow vibe. I slap quite a bit if that helps.
