Re: RCF NX L23-a on sticks?
Brandon - you need to give me a little credit. As I mentioned, the software multiplied ALL the units - including dB by 3.3 to convert from meters to feet. I recall from an old Tom Danley post, spontaneous combustion due to air friction happens at about 180dB. 450dB would be planet imploding.
As Mike mentioned, the big difference between the NX L23 and my JFLs is the ability to do angles other than the full 15degrees. I'm not a line array whiz yet, but I do know that vertical coverage tends to narrow as more elements are added, which is why I'm not assuming that this is all simple math.
If there aren't any gotchas to using the RCF boxes like how I use my JFLs, this system is all upside to me. Much better scalability, self powered, etc. I also believe I will be able to fabricate an adapter that will fit on my Gloal Truss ST132 stands that makes use of the subwoofer ground stacking arms so I can vary the angles of the boxes as well as put 3 boxes on a tripod stand.
