Will my SRX rig be enough for this venue?

Murphy Fine Arts Center/Gilliam Concert Hall  - Morgan State Unv, Baltimore, MD

http://www.murphyfineartscenter.org/pages/MFAC_Rental/gilliam/techSpecs_gill.asp

Seating Capacity: 2,036

Jazz Concert

What I have: x2 SRX725 and x2 SRX728 per side, I also have x2 SRX722 and x4 SRX718 available, which I thought maybe a 722/718 stack on the inside of each main stack to hit the seats close to the stage. Enough rig? I forgot to mention I do have a set of 715s, maybe front fill.

I am able to get a friend's set of SRX725/725, he has the same quantity of boxes, but I don't want to add that expense if I don't have to. Amps are Crown Macrotech-I.

My biggest concern is a ground stacked system in a venue with balcony seating, a little high.

I'm good on the monitor system requirement.



I know they have equipment listed/owned by the venue, but what I been told is most soundcos bring in their own rig, maybe MSU charges a pretty penny to use their system.

It's enough to fill the venue, but the real question is will it fill the venue properly. Properly splayed the 725s can work wonders, but not more than a pair at a time. After that combing becomes a problem. You may wish to run a dual PA seperating the vocals to a pair of 725s and the backline to another pair of 725s.

+1, any idea how the second balcony is selling?

We do a 1250 seat theatre with a similar rig. 2x725 and 2x728 per side, front fills are either 2x715 or 4x712 depending on the show. Main floor sounds great, the balcony sounds good in lower seating but seems to lose coverage near the back, we've tapped into the house balcony fills in the past, their SPL limits were a problem for louder shows though.

Main floor and first balcony should be fairly easy to cover with the main PA. I'd consider some fills on the top level (and possibly on the first balcony as well), find out what (if anything) is in place already as a starting point.

I think this might be one of those times a properly hung and shaded line array would surpass a trap rig.

Have you researched why those that brought in their own rigs did so?  Were they similar performances?  Have you looked into the cost to use the house system?
 
You might also want to consider the comments on the venue tech spec page cautioning that the venue was designed for acoustic performances, identifying very specific maximum levels and offering to "please take a moment to learn from our experiences" as it sounds like they are throwing up some red flags and that you might benefit from their input.  Have you spoken with anyone at the venue?
 
It appears that the house has dedicated speakers (KF650s and KF300s) for each balcony and looking at the pictures and seating chart I'd be rather concerned about getting reasonable coverage of the main floor and the balconies from ground stacked SRX725s.  You also didn't mention what processing or the number of amps you have available but that might be a factor if you start considering fills, etc.
 
Also consider some of the common issues with ground stacked speakers in such a venue.  For example, a reflection off a side wall that due to the vertical relationship does not affect the main floor but is very noticeable in some areas of the balconies.

Use the house system.

Like always, Dick has the words of wisdom and experience. With that said, Ive had to do similar halls (2k) with 2 QRx212 (for coverage) over 2 subs a side, it was more than enough SPL wise - material was religious with mixed ages in attendance. Although, balcony was empty.

Thanks for all the input, I will put it all into consideration. I was at the venue this past Saturday, but in the smaller Lamb-Turpin, during intermission I took a peek into the larger hall. I did meet the house engineer and talked with him for a bit, he was on duty for my gig. I didn't know at this point whether I had the future gig, it hinged on my performance for this first gig (new client via referral). I got the call for the future gig in the larger space yesterday. I will be contacting the house engineer for his insight.

My plan is to use my LS9 at FOH and a 2nd LS9 in monitor world.  Promotion/marketing of the show starts in a week or so, gig is in Feb.

Garry,  I have 2 thoughts on this room.

1) I would lay the SRX728 on its side and stack on top of it.  Tilt the SRX725 back enough and to have it the top balcony and then focus the SRX722s to cover the main floor seats.

2) I would stand the SRX728 upright and stack the SRX725 on top to cover majority of main floor and use the SRX715 for in fills.  Then on the first balcony use the SRX722 to cover the balconies maybe add a little tilt back on these as well.  It looks like this set-up will need some delay in the system, but shouldn’t be a problem with LS9.

Or you could avoid 90% of the grunt work and just use the installed EAW house system which is already set to cover the entire space...............

Garry,
        I am with Dick. If the house system is properly deployed, it will seriously outperform your rig in SPL, and more importantly coverage and clarity. I would use that if possible.
