Yes to the frame. Yes to the qualified structural Engineer. They are wired, strapped and safety wired as well. In NZ all forms of building for homes, workplaces, auditoriums, caravans, anything are checked by the local councils and specialised building inspectors are sent around. Then you are checked for fire safety etc.

Opinions on those straps for a permanent install?

There are thick wires as well that I could see but the photo doesn't show it. But as I said, i couldn't get high enough to have a real good look.
The Project manager is away overseas at the moment. He'll be back in a couple of weeks.

From what I know those straps will melt when exposed to some decent heat so not sure about the fixed install but if the wire rope is correctly attached that will at least make it safe.

Make sure that your hang points get inspected often, specially if your using straps like that.

Also please when you have the opportunity check how those straps are connected to the fly bar, I think I saw some shackles there and if that is correct the angle they are within those shackles might be a near the Max. Also make sure that the wire rope safety's are not slack, they should be tight, if the main support fails and they are slack they are very likely to fail immediately as well. The wire rope should also have some sort of tubing around it, it should not be raw wire in the trussing.

I see the top speakon.  If you zoom in you can see the safety cable between the span sets and the single cable between the rear angle adjusts.  Not a rigger but looks dicey.  The truss is also just spigoted triangle truss.

I'm talking about the rear angle photo, I don't think that the two photos are of the same hang. The rear one I don't see a cable connected to the speakon can even see the white strain relief in the hole so I doubt that box is connected. Would check that its getting signal but if there's no cable connected I doubt it.

Regarding the rigging I only see the straps and one very thin looking slack cable between the boxes and the truss so I doubt that will support that load should it fall.

Precautionary measure don't point any lights at the speakers.

I'll and get someone young to get up and have a real look at what's there and get it checked. I was there by myself in the semi-dark and stood on the highest thing I could find, taking the photos by flash.
And you are right, the back photo is of a different set than the side-on photo. However I could just make out some cables (about 4-5 mm across) very close to the straps.
Thanks guys.

Thanks. I did download the subwoofer articles and they are awesome.
I have contacted a mega-church in Auckland and a couple of sound guys with smaart are coming up to help setup in December. They are prepared to donated their time to help us. In the meantime, when I get a day free from work and all the other things, I will do as you say and feed in the manufacturer's settings.

Make sure you SMAART guys know more than just looking at a computer screen. I would guess there going to have dig into the guts of the system configuration as in the actual hard wiring configuration of the system.

It would not hurt to check for proper wiring of XLR cables, speaker cables and that all the drivers are actually working before even starting to program the DSP and starting to take measurements.

THAT is the FIRST step in "tuning" a system.  Make sure it is all working properly, in proper polarity, all the drivers working etc.

If you have issues there, then you are just wasting your time trying to "fix" it with eq etc.

Hello from a fellow Kiwi living in the UK.
Can't understand why you went with a cheap Chinese brand, When more common brands are available in NZ
(Yes they may need to be shipped over)

You mentioned they were used for Coldplay concert... Who was the sound company? For international bands the local rig used to be some Meyer hangs.

Next time contact http://lampros.co.nz/ who will get you some nice Danley point source speakers :)
