you need to describe the church
a cruciform church would be a different layout than a rectangular bldg
hang points would need to be considered
are the mr series rated for overhead suspension?
what is the rt60 what is the %alcons your going for
is the building treated acoustically
do you have /need conduit
are the looks of a ugly r&r box acceptable
a low q box like the mr is rarely the right choice for churches, due to
the typically long decay times of the room
you may be better off ebaying them , then getting the right speaker,
rather than try to force the mr into a application it was never designed for
the advice you get here will be worth exactly what you spend on it
I suggest you hire a qualified contractor/consultant

Seriously, listen to George and Eric about your need for a professional.
It's not just trying to find "jobs for the boys"....you have a couple of
major issues here.
First, in any professional sound install, it's not simply a matter of
hanging a few speakers and making it louder. Speaker cabinets are
specifically rated in terms of horizontal and vertical dispersion, and
calculations need to be done to ensure optimum coverage of your audience
(congregation) with minimum overlap to cause phase errors. Simply hanging
what you've got and hoping is likely to result in spotty coverage and
serious intelligibility issues.
Second, though, unless you carry whacking great levels of liability
insurance, you should NEVER get involved in suspending gear in a public
place. Again, there is a serious amount knowledge required and math to be
done...and falling speakers tend to kill people.

The first thing that I'll piont out is that your speakers have NO
provisions for being flown. That means that not only are there no
suspension points, but the cabinet does not included the necessary internal
bracing.
Based on that, Id suggest NOT flying your speakers. Bear in mind there
are specific requirements to what is required to safely rig and fly
equipment. Not following those put you and your church in a a bad legal
position if something does fail.
As others have suggested I would cunsult a local audio instalation
company. Also, if you're going to fly speakers, plan on replacing yours
with models that are designed to be flown.

Furthermore, if anyone here in this group were to provide you assistance or |
info in any form for flying those cabs and something did happen they would
be could be held just as responsible as you and your church.
Don't ask these good pro's to open themselves up to legal problems they
don't need! Hire a professional company that carries liability insurance!!

If you can afford to hang speakers that are NOT rated for hanging then
you have enough money to buy several churches

At the very least consider NOT hanging them but rather secureing them
with bolts through the cabinet to shelves built by a licesnsed contractor
The MR speakers would be easy to sell and I can get you some TCS
speakers that ARE rated for hanging and come with hang points
I would need to know much more about your church before I could
recommend models or placement
Are you within 5 hours of Syracuse NY?

OK, you've mentioned several times that you do not have the budget to do
the job correctly....
Do you have the budget to do it incorrectly?? I mean if you do
something now that's not right, you're only going to have to re-do it again
in the future. It's cheaper in the long run to find the resources to do it
right the first time.
FWIW, they say the average church ends up with three audio systems....
#1 - The originally speced system that typically gets cut back due to
budget cuts and cost over-runs. This system is OK, but never meets the
needs of the church because of the cutbacks.
#2 - This is the one where various people, of good intention, try to fix
the system with little or no resources. Typically the end result is worse
than #1.
#3 - Having realized that #2 doesn't meet the needs of the church, there
is a push to get a proper system installed that will meet the church's
immediate and future needs. Thus ending the process until the church's
needs change.

As a church goer and sound guy I suggest you do something temporary other
then just flying your speakers until you can get the budget you need. as has
been stated you can't afford a law suit if they fall.
even if they fall and don't hurt anyone you'll still be buying new proper
ones anyway.

Then I repeat this advice:

Ask your insurance carrier what they think about hanging MDF boxes with |
no internal support, that the manufacture has not designed or rated for
overhead suspension over peoples heads
