I'm looking to build a brite box similar to a Trace Elliot 4x5 4052h I have, but that rascal is heavy as all getout, so I'm looking for a lighter version. I want to use the Galaxy Audio S5N neo (PE 290-020). If I like it, I may build another, and use them as the upper end, along with my fEARful 15subs for a nice, light PA setup. I'd like a trapezoidal shape, and incorporate line array features, if applicable. Also any x-over info would be appreciated.
