Is anyone here using 12 inch speaker cabinets with a 15 inch speaker cabinets? I tried searching on here, and scanned through a bunch of headers. Didn't see anyone talking about this particular combination. Seems like it would be meat + gravy, no? Too much of a good thing? I get plenty of definition from the 12's I run. Wouldn't mind adding a 15 for this one band I am in that likes, ermmm, "ample" stage volume. There is also the very expensive way to raise the speakers closer to my ear aspect too. Anyone using this combination? How's it sound?
