na, i was at school today and i was thinking about what the salesman at the Guitar store was tellin me. he said that one 15 inch speaker had less area than two 10 inch speakers so two 10s are louder. This struck me as odd but i didnt question it. So i figured it out in class today when i was bored and stuck it here so i could have it when i got home. And yea a 15 has a lot more surface area than two 10s, 20 square inches more.
