I am in the market for a cab in the next couple months to mate with my SWR WM4004 and am only looking to spend around $275 max. I know this doesn't leave me with many options (goodbye bergantino, aguilar etc..). I saw a peavey 210 cab at guitar center for $180. I was thinking of getting a cab like that and swapping the speakers out for some kappa pros or even some eden XLT's if I could find out how to get my hands on two of them. (they handle frequencies as low as 30hz, lower than most 12s and a lot of 15s) Would this be a bad idea? I've heard people talk about tuning cabs but have no idea what that means. Would it apply to this project that I may pursue?
