I currently have a Behringer Eurolive B1200D-PRO 500W 12" Powered Subwoofer and it is AMAZING for when I am playing music inside. obviously, I know when it comes to using it outside it performs very differently. In matter of fact, when I play music outside and I use my sub I CANNOT notice a difference at all even when I am 2 feet away. My question is: How much "bass" do I need. In other words, what equipment do I need to really experience a good bass from at least 100 feet away. I know this is all relative to what someone defines as a "good" amount of bass. I was just wondering if it is even possible to get a good bass outdoors from 100 feet away that won't cost me thousands of dollars (more than $2000), and if so what subs would you recommend?
