So, what's the problem? This is how it's done every day in convention centers around the world. This is what corporate event audio is all about, well that and no mistakes, lots of RF, wearing a headset all day.

Lots of speakers, distributed, aimed down at the audience, and properly delayed is the way to get the best STI in a big reverberant space like a large airplane hanger.

Read and heed. 

Lifting devices using base resources might be an option. 

Aim them at the audience, put more listeners in the direct field, and enjoy the benefits.

Well thanks everyone for all the advice.

As for setting up various delay's I do not have the equipment to do that.

I will definitely try to get the speakers raised higher and oriented more towards the audience the next go round.

On another topic I was told I should have used the "RTA" mic and eq pink noise for the last set up. Anyone have a clue what that is? One problem with being a radio troop is getting everything related to a frequency thrown at you as if you know what you are doing.

Thanks for all your help.

What equipment do you have? Whenever asking questions like this it gets rid of a lot of confusion if you fully describe the situation. There may be other ways to help you maximize your results if we know exactly what you have.

Yes and no......but mostly no. 

There are easier and more effective ways to maximize your system capability by simply using your graphic EQ.  If you don't have a graphic EQ, you're kind of crippled.

If you'd like a PDF of how to "ring out" your system, send me your email address in a PM and I'll send it to you.  I cannot attach PDF's here or to PM's.

Uh what's your MOS troop?

If you don't have delay, no problem one less thing to adjust.  8)

The way to think of this is that the sound coming out of the speakers forms a cone. You don't want the top of that cone putting energy into the ceiling to bounce off and create reverberation. So point the speakers down, and starting from higher up lets you point them down and at more seats.

The delay for extra speakers is to fool the audience into thinking all the sound is coming from the stage.. For spoken word (like comedians) it is better to get the speakers closer to the troops, so they can understand the words, than fooling them about where the sound is coming from.

RTA (real time analyzer) is to help adjust frequency response... Not your major malfunction which is room acoustics, For now worry about how you point the speakers.

I have done a bunch of Corporate meetings for a high profile personal
jet company in there smaller maintenance hanger 125'x400'+ 400-800pps.
I use Ev X-Array cabs flown and pointed right on the seats. Keeping the energy off the walls and ceiling is the name of the game hear. I had experimented with different heights and placements before I came to mostly covering the first 20 rows with direct sound and the rest where getting the indirect bounce best compromise.
 I mix these shows on an SC48 so using groups to EQ the Vox and Music separate keeps the music sounding more full and the Vox band limited then your house EQ is for problems and quick show fixes.. Rolling your HP up till it just starts taking the balls out is advisable.
