A few years back we removed a center speaker array (2 horns and low box) that sounded and covered pretty good and replaced it with the 5 K12's arrayed as shown. (I really had no input in the layout). I think it sounds better than I expected, if the side fills are backed off a little-but pastor realizes that the arrangement muddies up the sound in places-we have pretty much gone to no sidefills for speaking portions of a service for better clarity-but the sidefills give better coverage on songs.
Pastor is now telling me he thinks he overkilled the room (several people have said that)-and the reality is we could use the extra K12's elsewhere. He wants to rearrange things-perhaps bringing the sidefills in and changing center to one speaker. My first off the cuff thought was to change wiring so that I can run either the 3 in the center, or the center and two relocated sidefills and do a comparison.
I've followed on here for a long time and I understand the point source point of view and adding speakers for coverage. I feel like using a "spread" center cluster might give better coverage and less overlap than 3 close together. I know that doing software modeling is the best way-I also doubt the money/desire is available to do that. Thoughts on how far apart before the speakers start acting separate vs together? I know in theory, as soon as multiple transducers are used-but practically speaking? This room has plenty of reverb-so getting really crisp sound isn't going to happen anyway.
Just looking for some constructive feedback
The attached pic wasn't taken for purposes of this post-but it does show the arrangement of the speakers and room-it is symetrical in the portion not shown.
