How is the building of the tops going? I would imagine that the midrange from those horns would be very powerful but you may find that they lack a little brightness with out boosting the gain around 17-20k, i would recommended several smaller compression drivers 1" or 1.5" rather than a single 2" or a combination of both so you have more control. many 1" compression drivers can really change the sound if setup correctly. A favourite layout of mine on smaller speakers is a mini array of tweeters usually 2 in series and two in parallel, 16 total if you like for more control and power but it starts to get expensive and difficult to build. With larger applications i'm thinking 4x 1" compression drivers would make a nice job. 2 sets in parallel and those two sets in series to retain the original impedance but increase power handling. The other advantage with using 4 1" compression drivers in one cab is that the horns can be splayed out at different angles to get a greater coverage in the room. (which is kind of necessary to avoid interference patterns, this also depends on the shape of the horns used).

If you want to do this kind of thing, get some swivel clamps at least, so the thing can be clamped together properly - and actually resemble something load bearing. They are cheap and common - used by scaffolders, absolutely no excuse here. Leave the cable ties for.... *cable tieing* and use clamps for *clamping*! Also build a proper base for the thing [using truss baseplates] so it cannot tip forwards or backwards.

try getting the midtops up higher next time too....

sorry to be harsh, i can see you put a lot of effort in, the lighting and set looks awesome, but the little things cannot be ignored!

 
I 100% agree with you, they did too many wrong stuffs with the trussing. I will request they buy clamps like you suggested.

And finally, some pictures of the light just before the opening of the first gig.

























I think these young guys made a good job transforming this small venue in a single dance floor just for 2 nights.

Hello All,

I will start to work on the tops next week.

Waiting for this, here is a few pictures of the last use of the 186 this week-end.

My son is working with another guy to create 2 events based on young talents. Everyone in these organisations (including the 8 DJs) are from 16 to 19 Years old.





I just gave a hand half a day for the setup.





The Amp Rack with a borrowed additional amp and a processor:



Backstage:



186 Horns on side of a dual 18 sub using the same RCF drivers. So, with the processor, we worked 3 ways: Sub, horn, full range speakers. Crossover points was 80 and 150.



DJ corner. The mixer we used (DJM 600) was not yet installed.




Will include some pictures I took just before the opening in the next post.

lil comment here, stack the 186's sideways one on top - get the SMT212 up to height!

Going to be a potent rig once complete! Time to get a proper bass amplifier and speaker processor also....

You are right, this is better like this Smile
