Lightbulb Speaker delay circut design?

Hello all,
First off I'd like to say that I'm new to this site and also that I wasn't sure where to put this post.
I run live sound for our church. We use a PreSonus digital board.
I did do all my mixing in stereo till we expanded the seats in our church. The people now sit hard left and right as well as in the middle so stereo mixing isn't a great idea as I got many complaints the first performance with this new setup.
I figured out, after running my pc through the speaker system, that the room works extremely well with a mono source and a nice 10-ish millisecond delay on the right channel. Right away I realized how much better the church sounded.
The signal was a dual mono into my izotope ozone with an added channel delay. (Not sure which channel was being delayed so I assumed the right one)
It turned out it had the same characteristics of my stereo mixes had in the room which gave me an idea.
I cant use my pc for the services, only the board so i cant use any vsts and such.
The amps have no delay on them so my only option would be to get some kind of circuit that i could run on the right channel (Or left?) that would delay it by 10 to 20ms.
I'm not sure if this can be done but I hope it can as the band sounds so much more professional when done in stereo.
Does anybody know where I can get some kind of walkthrough on how to build such equipment or is it possible I can get it cheap?
Thanks!

Thats probably the simplest delay circuit you can find, wether it meets your requirements im not sure.

First of all, are you talking about delaying one channel 10 msecs, or adding reverb?

If the former, where does it "sound better"?

Stereo sound pretty much defines a line between the speakers where the sound is balanced. The further one is from that line, the less balanced things will sound, so if you have a wide lateral spread among your listeners, mono is the only way everyone will hear everything properly.

I played it back and no matter where I stood, the tone and clearity didnt change. I know it sounds stupid but it really didnt.
I hate to mix in mono because it doesn't sound how I picture it would sound and I find myself adding frequency changes when there should be none.

I suggest you have a look at this:

Behringer FBQ100 66.62 IN STOCK (6 Aug 2012)

It will give you LOT'S more things to play with including your required delay.

Why would they, it really makes very little difference to a live performance - although it's quite fun panning the guitarist as he runs across the stage

Same for discos - no ones cares if it's stereo on mono, in fact all the discos we use to run were only mono, including a permanent install in a rock club we used to run.
