Hey gang, I'm looking to replace the 12" speaker in my Mesa Powerhouse Jr.: Why? Because I'm rewiring it so I can run both sides of my Strategy 500 tube amp through one cab. My plan is to run the 8"s one one side, and the 12" on the other. The 8"s are 16ohms each, so if I run them all in parallel, the total load will be 4ohms; but the 12" that's in there is at 16ohms, which my amp doesn't have a tap for. I want to find a 4ohm replacement, so each jack on the cab will be for a 4ohm load. I don't generally care for the sound of Neo speakers, and I'm looking for a speaker that sounds similar to the one that's already in there (which is an Eden of some sort). I'm looking for a big, robust, midrange heavy tone. I don't care about weight - the enclosure itself weighs a ton, so adding or reducing magnet weight won't be much of an issue. It needs to handle about 200 watts. Any recommendations?
