3 boxes isn’t a line array except with the constant curvature stuff.
We have the JBL VRX in stock and it’s the devil everyone knows. Doesn’t sound all that great but get loud as F*#% and quickly deploys on top of the subs.
Yep, there's no 'line' aspect to constant curvature arrays. But it looks like more than one box, so that must mean it's better...
Nah, the VRX sounds 'ok' and does get silly loud. No real line array properties available other than minor shading. Adding boxes only increases the vertical coverage pattern, which quickly becomes silly.
But, it's easy enough to deploy that it rents out. There are worse options on the market and if you know what you're doing, you can get decent performance out of them.
