I'll be running multi stages for a few larger outdoor festies for the first time this summer. This will be my second summer doing a larger outdoor gig. apx 2000 people. Have a great PAS system for the main stage but I want to PU some cheap 18's for the side stage. Is there a particular sub cabinet design style/maker that you have found carries best outdoors on grass? FYI I have a few home made down firing metro subs (kinda like JBL jRX100)that I dont think will cut it outdoors by themselves.
