I'll just say this. The Ampeg BA300 combo's claim big wattage, but do not allow for adding any additional speakers to them. The speakers that come with the combo, 2x10, or 1x15, will not be able to utilize all the power available- and in order to "get louder", you NEED more speakers. Conundrum. Therefore, it is ALWAYS a better idea to get a head with one cab to start, and add another cab later when you realize how little volume you'll get from one. Buy once, cry once, is how the saying goes. Once you lay the money out for the combo, you're done. Cannot expand. Better to have more than enough than not quite enough. Best of luck to you.
