weird, i somehow missed both jbl and eaw stands in frankfurt.
these look like a solid design. probably 1,2, or 4 12s or 15s either horn loaded or angeled baffled with a sufficiently large hf horn. also looks similar to the d&b C4, a proven box.
that eaw uses some very interesting proprietary processing, could be a nice box. unless it ported, not sure how it could go low, though.
however, nations in dc did not impress me.
