At least provide links to the specs for the equipment you have so we don't have to go searching.. Sorry, I don't have a lot of spare time right now..

Final question...

What is the system used for? Because if it's DJ your set properly for power for the tops..Subs ..not so much (unless you have 2 amps for subs?) otherwise your going to be restricted in dynamics and need to consider that in the crossover points for live sound applications...

Hi the sound system is used for church service and we are using a full band (Keyboard, Guitar, Bass & Drum).

Thx

Ok, so then Here's what I would do (assuming it's not all out balls to the wall concert rock)

Sub:
HPF 40hz BW18
LPF 90hz LR24
Tops
HPF 90hz LR24

You have limited power for the subs (you failed to answer if you have more than one amp for the subs) and assuming one amp, you cannot go bridged mono, so you will only have 750 watts per driver for the subs.

Note, pre recorded music is usually heavily compressed, so amps ratings should be pretty much continuous speaker rating, watts wise...Live sound is MUCH more dynamic and requires more reserve power...

I recommend you use the PEQ's available for room modes.. and use the GEQ to smooth any speaker equalization. If you can get the low end out of the monitors (like 150-180hz HPF) that would go a long way toward helping the FOH sound.
