I am looking to start converting my point source system to CDL12P's. I currently use two per side dual 15's with horns point source speakers for medium size outdoor music festivals I do. I want to convert over to using all CDL12P's but will have to do it in steps for money reasons. However I want to start off with two of the CDL12P's for small inside gigs and would like to use them for center fills on my outside gigs and eventually buy enough to hang three on each side. Any issues with using them for center fills?
