My worry is if you have 4 in a center cluster at full throttle to what degree will you kill the lead singer standing immediately behind them when deployed in the described fashion?

Is it doable or is further steering by arraying necessary? (which would be space-consuming)

Keith Broughton:
The cabs were laying on their sides.
The venue was an outdoor festival, say around 8000 people or so.(16 box array)
I have used as little as 2 a side in a band/corporate event in a large ballroom with good results.
I would say that 8 boxes, properly powered would perform very well.
Just my opinion....
As for steering, it can be done with time delay rather than physical positioning.
So far, even with a folk show (8 box array standing), there have been no complaints of excessive low end on deck.

As Keith noted, forward directivity is better with a cluster of horn loaded subs-I wasn't worried about your singer. ;>)

I'm trying to get a feel for sound levels with four to eight of these and how large a crowd Keith's covered, indoor v. outdoor, music style, etc. 

I suspect four would handle up to 500 outside for rock n roll, just trying to get some real world info.

Best regards,

John

Check the Danley website, Franz Francis stacked 20, 5 over 5 per side.  In the portfolio tab.  I also think there's an old post in the archives that has a measurement of 4 over four, and it shows directivity.

How about a link? There's a lot of tiny thumbnails in that portfolio.
