I have an Ampeg Classic 8x10 currently. And it's fine. Very punchy and whatnot. But I've been toying with the idea of removing the bottom four 10's and having a new baffle cut for a ported 1x18 to get more depth while still relying on the top 10's for punch/clarity/cut. Would that just be stupid? Anyone ever played a 4x10 + 1x18 setup?
