Well, if I went with the 15 inches for $549, I wont be getting a sub for a while. If I just had 2 B215D, would that still be OK for maybe 50 people? When I get some more cash I could go and get a decent sub and it would be a good setup. But also back to the original.. agh it's always changing, just add money and you'll get what ever you want lol. Anyway if I had; 2x Behringer B210D and, 1x JBL JRX118S 18" Compact Subwoofer Would this set up be better than just 2x B215D's? Or would 2x B215D's still be 'acceptable' and then once it was with a sub it would be waaaaayyyyy better than 10inches? I don't want to spend a half arsed amount and than have to upgrade later... Remember I'm not a DJ doing gigs all the time, will just have these at home and use them every now and then.
