Lots of hate on some other forums

Thanks, Bill. It's a shame they only say "professionally designed" and don't mention your name specifically. But it's awesome to see your stuff being employed in that kind of set up. And ...DAMN!!! That's a huge system!

...a scaffold, or other means that essentially ground stacks them.

My favorite option... Just keep piling up Titans or Tubas until the desired height is reached

The fly gear is a concern for those trying to run the DR cabs in a traditional line array configuration. But what could the fix be? Without a standardized options, DIYers are forced to DIY. Would one get a license from a structural engineer?

I agree that it's pointless to build concert PA tops with no way to apply them. Honestly, that's why I stick to boxes I can stick on poles...Otop 12 and maybe DR200 in the future.

This has been discussed quite a bit at times, in a few threads, in the forum.
Yes, get your licence/sign off from a structural engineer. In fact, work with that same engineer right through the process.
Bill has never said these ( PA tops) can't be flown, he has said "you can't rely on the structural integrity of the cab to fly them, each cab must be wholly enclosed in a flying structure".
It's not impossible to do, it just has to be done right.
Not just for insurance and litigation. No one goes to a band or show or dance party or whatever, thinking they may be killed, injured, or otherwise harmed by falling PA.
It's a hell of a price to pay for a bit of fun.

Even cabs on poles require constant vigilance.
We did hear of a story of little Johnny who ignored their parents, knocked over a cab on a stick, and said cab landed on little Johnny...

+1. I like it!

Grant, thank you. And I agree entirely. If it were me I'd probably just stack them. Then again, if I ever had a NEED for DR300s that stance could change.
