I plan on purchasing a second cab for when I want to be stupid loud. Mostly, I just want to move lots of air. It can't be a super huge cabinet, as this cab will be replacing a big sunn 2x15 folded horn and part of the idea is to save a little space, and maybe get something I can fit in my passat. Schroeder 21012 - Nice size. Supposed to get pretty deep, right? Bergantino 610 - I've only heard good things about this cab. I expect the Eden might have a bit more bass response, and the pair might sound nice together. Cost? Bergantino 2x15 - I haven't found any reviews of this cab. I'm intrigued though. Cost? Eden 2x15 - I've never heard a 15 inch speaker enclosure made by eden, so I'm in the dark on this one. Any comparison to the Bergantino? It's a little bigger than I'd like to go, also. SWR Henry the 8x8 - I've only heard good things. Lots of punch, good volume. That's really just a start. I'm generally partial to the idea of a 15 or 2. I play mostly noise/garbage. I won't be making this ourchase for about a year. Right now I'm mainly looking for contenders to try to hunt down and try out. My only real guidelines: It has to be a 4 ohm cab. My budget is around 1k Any suggestions?
