Danny,

Please answer Brad's questions regarding the size of you space. You gave us the dimensions, but you did not say-

is the the platform (stage) on the 44' or 57' side.

Also do those dimensions include the size of the platform, or not.

Sorry, here is the pic of the chapel floor plan. I hope this will help....

That helps very much. Looks like you are trying to cover an area that will be about 45 wide and 35' deep (assuming some space between the edge of the stage ant the front row)

I would have a couple of general recommendations.

1. I would want to install the speaker horizontally because of the 14' ceiling.  

2. I would suggest just 2 boxes in there, and a sub

3. If $3500 is the absolute ceiling I would suggest holding off until you could get to around $5000. That extra $1500 will go a really long way in terms of the end product.

Thanks Gary.

What speaker would you recommend?

I was thinking about QSC KW122 instead of K12...
But I realize it will be hard for me to turn on/off the speaker everytime.

What do you think about
2*EAW FR129z with QSC RMX 2450 amp?

I also ran couple of (100ft)2C Microphone cable on the top of the ceiling.
does 2C Microphone cable is okay to use as speaker cable? since the cable is pretty long,100ft ran.

I am going to buy speakon connector and neutrik XLR connector.

Should I use 2*2C Microphone cable to use as one cable?

NO- you need to ran 12 ga speaker cable.

Don't EVER use a mic cable as a speaker cable.  You are only asking for trouble and possible damage to your amplifier by doing so.

I used those EAW frz129s in my last church and liked them very much. The QSCs are nice as well.

As for turning powered speakers on and off remotely you could use a product like this-

http://www.bhphotovideo.com/c/product/181308-REG/Furman_MP_1 5_Miniport_15_Power_Relay.html

this would be able to power both speakers.

As Ivan mentioned you do not want to use mic cable for passive speakers. Typically mic cables are 22ga or less. You would be ok with 14ga, but I would not suggest anything less for mains.

If you run power through the mic cables you will lose a lot of performance, and potentially harm the equiptment.

Oh... I bought 1000ft spool cable...
What if the 12GA cable does not have ground shielded? is it okay?
And as far as the price, they are pretty expensive..

This is something I never know about it.
We currently using microphone cable as speaker cable.
Wow... I learned something!

I will probably have to buy 12GA cable and re-run the wire.

And important thing that, our budget is little chagned..
We probably have to get the subwoofer sometime next month.
We might just going to buy the 2 main speaker...

I guess we might just going to get EAW FR series.. and we will add sub next month.

12" should be loud enough to cover the drum or any acoustic sound? If the speaker could not cover the drum sound, then I will let drummer use rose stick...lol

The speaker wire does not need to be grounded or shielded.

The difference between a 12" and 15" has let to do with loudness and more to do with bass response, and frequency response in general. In most speaker lines the difference in performance between the 12" and 15" is relatively minor. I prefer 12"s in the church setting because to me they seem more articulate (often they are crossed-over at a different freq), and they are simple physically smaller (which is typically desirable).

With out a sub I would just hold off sending the kick drum, and the bass guitar through the system.

Thanks Gary!

More question comming...
You mention the 12GA speaker cable
Instaed of buying expensive speaker cable, can I use any 12GA cable?

I am not sure yet, but most likely we will end up buying a sub.
Instead of put the sub on the floor, would it be possible to mount the sub with the main speaker on the ceiling?

If not, we will have to run a extra speaker cable for the sub later.

And I ordered 7 x 2female microphone wall plate. I will use about 120ft cable for all the wall plate to mixer.

120ft is okay to use? Do I need to use any repeater?

It does not need to be expensive wire, and it does not need to be 12GA. You could go to your local electrical supply house (not best buy or guitar center) and get 14GA speaker cable at a pretty affordable price.

I would not try to fly the sub for a number of reasons. For the sub go ahead and use 12GA.

120' is no problem for mic lines, no repeaters needed. What is important is that you use the proper wire such as this: http://www.markertek.com/Cables/Bulk-Wire-Cable/Bulk-Audio-C able/West-Penn-Wire-Corp/291-BLACK.xhtml?WP-291-1000YW
