I blew up my cab at band practice tonight. It's a custom built Emperor 4x12 rated at 600w at 8 ohms. I popped the cab open to see the speakers and they were all Eminence Alpha-12A. Two of them were hot to the touch and had a burning smell about them. After testing the speakers to see if they were putting out anything, I have concluded that the speakers are 100% kaput. I was using a Aguilar DB750 and several pedals plus a Musicman Stingray and the cab just stopped making sound. With all that being said, I have a small tour coming up in three weeks so I need to get some new speakers fairly quickly. What are your recommendations for replacement speakers? I'm not particularly inclined to use the same speakers for fear of the same thing happening again. Maybe a higher wattage rating...? I'm not sure! Please help!
