Thanks for everybody's input. Just to give a little more information...

I have no desire or even think it's feasible to make the room "dead", just want it a little deader. In fact, if I went too far, some of the other stuff that goes on in that room would suffer, like the un-amplified children's choir concerts... The room was renovated a few years ago, and I'm certain no thought was put into the acoustics of the space, only the aesthetics. I really just want to do something that probably should have been done when the room was renovated.

The college group that meets in there is starting to use a full band, and the liveness of the room has become a real challenge. A drummer can use brushes and play very lightly, but as soon as a cymbal is struck that's about all you can hear. With all the hard surfaces, it's hardly a surprise. I was asked about getting a drum shield for the room, but I know that will do little to fix the actual problem.

The DIY solution I'm currently considering will use 3" panels set off of the wall about an inch, with Owens Corning 703 or something similar, so I'm definitely looking at a more broadband solution than 1" panels.

As I was writing this I see someone said they've never seen DIY panels that do any good, so... I don't really see how just the fact that it's DIY would make it less effective, when it's the same materials that are used in commercial products.

I'll rephrase...I haven't seen any DYI panel that works as well as a Perdue panel. (No I'm not a Perdue salesperson. Just had really good success with their products)

The Perdue panels are not made from standard off the shelf commercial materials. That's why they work so well. It may say rock wool, but the manufacturing process they use is not something you can duplicate yourself.

The problem with DYI panels is you don't have any idea of what it will be like until it's done. There is virtually no way to know what the final NRC rating will be.  You are just rolling the dice.

A good quality engineered panel with a known NRC value will often times cost less overall because you need fewer panels. Their EconoWedge panels are less expensive than you may think.

At least 3 of the scrolling pictures on their website are from jobs we did.

It is easy to have good congregational singing in a dead room.
....

But that will add a couple of "zeros" to the budget-so that is not for everybody.

If it was "easy" it would be common and not add a couple of "zeros" to the budget.   :)  No doubt the designers have invested a lot of effort in the design concepts.

MAKE SURE you use FIRE retardant coverings.  Or be willing to accept the liability if something should arrise in that area.

There is a good bit of direct costs (speakers, amplifier channels, processing channels, low noise mics. low noise mic pres-lots of speaker wire-and installation time) involved in these systems.

There are several different approaches to "acoustical enhancement".  THey each have their own set of advantages and disadvantages and are not all the some.

Ivans acessment is correct
your space could be done by a company ,but
 My prevoius church and i have built and installed diy panels 2" in the 2 gymnasiums/multipurpose rooms with excellent results.
   703 series fiberglass panels do not know whos "manufacturing" them.
The quality of the build and panel covering and application  is the key. fire retardant treatment is required. it can be purchased at amazon
and there are endless suppliers of the materials needed.

     some informative reading and plans

With DYI panels you'll never know what you're missing vs. a "real" panel spec'd and installed by someone who does it professionally.

DYI "may" do some good, but they will never be as good as a real panel. I have seen many times where DYI ends up costing more.

But can you provide certification of the fire retardant qualities of your DIY panels?
