O.T. Onken W thoughts ?'s

[juniper]

I was wondering what you all thought of the Onken w as a speaker box with dual 416 8b's. Or if any of you have heard one? I recently acquired a Klipsch k-402 horn and they are pretty large ( 41.5w X 26.5 H X 22 d ). It supposedly plays from 380hz to 20k. I was thinking of getting one of the very large Altec horns but they are pretty pricey and hard to find.. If I went with the onken w, it wouldn't be the sand filled one, thats just to heavy. Just simple 1" ply and some heavy bracing.. Thanks any thoughts would be great!
