Ok guys, I have searched and searched, but I just can't decide. I have an SWR SM-400S and a Nemesis 2x10. I want a cabinet that can handle at least 400 or 450 watts@4ohms, so that I can run the SWR into it bridged for rehearsals. The Nemesis handles the highs very well, but does not handle the bottom end. Basicly, I need to decide what would be the best cabinet that could be used by itself or with the 2x10, something that will really provide the lows but also have some highs for when I am using it by itself. Price range is <500, but I buy all used gear. Weight needs to be less than 70lbs. I've been looking at the Nemesis 4x10, and several kinds of 2x12's that have tweeters. Let me reiterate that I am not that concerned with the highs, since I can always use the 2x10 with this new mystery cabinet. Overall, it needs to be LOUD... lots of bass response, lots up *thump*. I'm pretty sure I've contradicted myself several times during the course of this rambling post, but if you guys would weigh the options(4x10's, 2x12's, 1x15's) I would again be in your debt.
