All I can say is I heard a world of difference when I added the extra layer of 3/4 ply.
This is also one of the benefits of a triangular box as GM said, we can get by with less thickness & bracing with a triangular corner box now I have to find that post about the baffle being 70":doh:

ADDED: @ GM posts 108,103, we discuss a baffle height of 70" to try and get the box to a 30 Hz tuning.I guess the question I was asking does the cabinet have to be as high with the woofers in a horizontal position.If i can go with a height of 60" aand a width of 36" with the 10" setback and then the 24" point where the 2 sides will meet.Should be plenty of Cab.volume. should it not ?? Drawing coming to give better idea of what I'm talking about.
