GM, thanks.

I now get the point re location of horn.

So, to simplify our discussion, I want to cross over at 1200. As such, is my project like a M19 albeit slightly taller?

With the 1200 xover point, is there any gain in going for the larger 511?

Oh, one other thing, I asked about ideal cabinet volume for the 416. Any thoughts? At present I have 160 liters, but with a rebuild, this can go to 240.

Kind regards
