Hi,

For the o/p, have a look at this paper from JBL about their FSA(Forward Steered Array). Somebody has obviously had better luck persuading a company to try this concept. I tried some years ago, and all I got was disbelieving stares. Oh well. Hope this helps.

Iain.

David,

That is exactly what is being discussed, except that there were 8 subs in each row. I also started a thread on soundforums.net. On that board Randy (Carrie's FOH guy has joined the discussion) and there are pictures of a similar flow version on a Godsmack tour.

I am very excited about where audio is going with concepts like this.

John

Hi Dick,
I think this is what is being discussed (assuming the cabs were stood upright).
Cheers,
David.

I also couldn't really figure out the original description. If I understand the picture correctly it's a sort of tunnel of subs under the stage firing first under the drummer then out towards the front of the stage?

But then I can't make sense of the "assuming the cabs stood upright"-comment...??

Hi Frederik,
The "tunnel" description is about right, though from the OP I think there was one such setup each side of the stage rather than a single central one.

My comment about the cabinets being upright was in reference to the fact that I only show one driver in each as if you were loking down on a 2x18 from the top - just because it was quicker to sketch up that way rather than doubling the number of drivers per box in the pic.
Cheers,
David.

This discussion also taking place on 'another' forum.  The linked pic shows a flown variation.

The thread also contains some additional reference material.

Have fun, good luck.

The flown array could be described as an end-fire dipole.  In the horizontal plane the end-fire arrangement gives a cardioid type pattern.  In the vertical plane, its a dipole and the bass directed towards the stage a roof will be reduced…. perfect !
