I am currently on a quest for more bottom end. Would I get more bottom end from a 4x10 + 1x15, or should i aim for a 4x10 + 4x10? I have a small car, so an 8x10 is out of the question. I am playing a Hartke 350 watt head, and my band plays hard rock I'm thinking about hunting down some AVATARs, as I hear they are quite the bomb. I don't know what the availablility is like in Australia though. I can't get to a music store with all the required cabinets for a while, so any opinons are welcome. Be assured, I will try for myself before I buy though!
