It is not true that bass is tighter on smaller diameter drivers. It is ALL about the design.
Most of my people have come back saying they wished they had gotten the 15", it sounds as good as the 12, with lower low end for the little kid in them...
Now as you are going with 4... and I'm sure you want a minimal of amplifiers... The orion XTR pro2400 comes to mind... you'd need two of them, one for each pair of 15" drivers. Should give you about 1200Wrms for each driver.
My question is, why in the WORLD would you need 4? I'd suggest you buy two first, and if you still feel you want more, expand from there. Save yourself a little money, just in case you don't need all that ka-boom.
