I highly recommend you to put some cover over the t60's, I had some nasty noise from one of my t30's, I had no idea what could have caused it, brace vibrated loose or broke driver, but it was actually a piece of candy paper that was sucked in to the front of the driver and caused a hell of a lot of noise. So if you don't want to take your t60's out every now and then to clean them inside by removing the cover and driver... Not sure it will happen to you but these cabs can obviously work extra as vacuum cleaners from time to time! But on the other hand this has happened once in maybe 500-800 hours running time on the subs.

The good part regarding distortion and bad sounding cabs is that no matter how hard you drive these ones it doesn't sound bad as long as it's set up right! Very convenient and comfortable set-and-forget situation

I am very interested in your initial thoughts and experience with the sound in the room, please share with us!
Also I think you will want to install a spl meter in that room for the dj to monitor and tell them what levels and where the threshold of pain are... It's a nuclear weapon you have there and if you don't pay attention you might loose 50% of your beloved guests after the first night(I mean they won't die, but not show up again). A lot of stuff can go wrong the first night, don't let it be collective nausea and hearing damage that can be avoided!

As a long time Tinnitus sufferer, about 40 yrs now, I highly commend the suggestion of an SPL meter to monitor the levels.

+100.

-100. Run sound levels from a remote, locked sound-board. Set sane SPL limits and make it so the DJ sounds like shit if they overdrive the outputs of the DJ mixer.

FTR, I like the idea of a triggered, flashing "SUCK BUTTON ENGAGED" light that will flash brightly behind the DJ if they get stupid. If it pisses off the DJ, they are the ones you don't want in your club, anyways.

The board doesn't need to be inaccessible, the amps and limiters do.

I'm just talking from my own perspective, and how much I would like to call myself a audio nerd and all that, it doesn't matter if I don't have a visual or audial reference point to look/listen to, and as I'm always standing Behind the pa I need to be able to monitor the audio the sound going out to the audience in another way. I don't think I would care about if there were a box that made me sound like shit if I played above a certain level, I would end up there anyway either I want it or not.

In the end a dj should know and take personal responsibility for their show and how it is perceived, a spl meter would help me with it, a box making me sound like shit above certain levels would not.

Those subs look like they're just waiting for douchbags to toss their trash down the throats.
The mouth of these subs are going to be lit up so I didnt want to hide them w grills, however we do have to security that stand in front at the corners of stage that will keep people from trying to do stupid stuff..

Thanks 88, You should hear it!! Its insane!!!

Well I fired it up yesterday and only flattened the response out but haven't eq'ed to taste yet, and its pretty dam impressive! We ran the system into the 130db range and it was so clear that it didnt really bother any us.. I agree you cant let it rip all night but ever now and then its a go! So far the room sound pretty dam good accept for the reflections mostly due to it being empty while testing.. I think once the room is finished with fabrics, curtains, bodies, coaches etc. it will sound even better..

Luckily the amp rack and limiters are out of reach to the DJ's and the driveracks are remotely controllable from the light/sound tech booth so we will be able to limit the overall volume.. We'll give a little extra for the headliners but we def wont punish the customers.... unless they want us too :loler:

I haven't done any delaying of the cabs just yet because I'm unsure what to do.. From what I understand I need to make up for all that horn path within the Tubas? Just how much delay is that worth? Do I delay the tops? I'm also going to attemp to delay the outer cabs as well to see if there is any noticeable difference.. Any thoughts?

I'd start with an 11.5 ms delay on the tops, and work from there (downwards most likely)

also, make sure you use similar slopes and filter types (linkwitz/riley 24 for instance) on the hipass of the tops/lopass on subs (for similar phase delay).

Delay works out at about 1 msec per foot.
So if you're biamping as well, and want to align everything to leave respective mouths at the same time, you'd start with the 11.5 sine suggested, about 3msec for your mids and .5msec for your HF if melded, or about 1 msec for compression drivers.

I've seen plenty of people say though they prefer LF to lead tops, by a bit...

edit: oh, and this ^ is on the proviso that all cabs mouths are at the same line in the sand so to speak. So if your T60 mouths are 6' in front of the nearest DR mouth, reduce the delay by 6msec (to 5.5 msec)...

edit2 lol:
11.5 secs would be based on the path length of the T60's being 11 1/2 feet...
Built:
DR 250: x 2 melded array, 2x CD horn, March 2012 plans.
T39's: 4 x 20" KL3010LF , 2 x 28" 3012LF.
WH8: x 6 with melded array wired series/parallel.
Bunter's Audio and Lighting "like"s would be most appreciated...
