Then somebody puts 50,000 people in front of it, each generating 100W of heat, or substantially more if it's a rave and they are all dancing. What happens? So you have bigger chance to fix it using Danleys? Lift crane up/down? Tilt more? https://www.youtube.com/watch?v=sIpJ5sgdb6Q granted, not even 50 people, but it was windy That system there sounded horribly wrong. No dynamics at all. Dead at 50hz, dead at 8Khz. That small Hormonic Design boxes that were hanging beside it, killed it badly in sound quality. Just goes to show that any kit can be setup badly! It has quite low HF distortion though, which side by side with boxes that have single drivers driven super hard, sounds like a 'dull' HF in the upper region.

Just  to set the things clear, the year before that they had a different setup that sounded excellent.

While this thread creeped a little bit into sub territory, 50 hz would have been covered by different speakers than the tops, and you would be one the few people to say that danley's subs suck.   They have to... If those basses would be fast and punching then how would you time align them to the Jerichos precisely? Add another crane?

I find with a single 2nd order Allpass at 150Hz, with a Q of 1.5 works pretty good in a similar configuration, myself

But I agree with Marjan sadly, it wasn’t a great demo. The guys used APL TDA for tuning I believe and I’m wary of any software that claims to be magic and only needs you to wave your arm around your head a few times at one position to get ‘perfect sound’

Saying all that, nice article in LSI this month about point source still being relevant.

Admittedly, bit of a puff piece about Autograph, using KV2, doing some tours to "provincial" theatres, but it is the LSI mag!

However to quote p22 of LSIonline Jan 2019 edition:

Andy Sharman - Sound No1 on tour of Kinky Boots stage show wrote: It sounds a bit old-school, but in reality, if there's a part of the room that we need to cover, we install a loudspeaker, and point it there - it just works.

He also mentions that most small theatres don't have fly points for line arrays anyway, so point source is easier to move from venue to venue.

Back to what should be common sense really, right tool for the job, and LA is just one tool.

Autograph aren't the only ones talking about it

And I get you on the RCF, it's a tool for sure, and it doesn't sound bad, and the rigging is pretty slick / invisible which sadly is what matters more to most events than the overall tonal quality.

Flexibility makes more business sense even if it doesn't make much sonic sense.

Since we're talking about the HDL6A, how about we look at some data? All single box, driven with AES Broadband signal:

Horizontal isobar


Vertical isobar


Transfer function


Horizontal off axis freq response deviation


Same but vertical


Directivity index


Max SPL (although it seems they have entered max SPL data as sensitivity and vice versa in the GLL file, curious if that's a trick to make plots look better in Focus 3...)



Make your own conclusions as to the effectiveness of the horn and how well the box complies with it's stated nominal dispersion or line array theory. I'd be applying a LPF at 16KHz myself, to avoid that splashiness above.
