Your strip of wood will mess with the tuning.
Early Valencias were the same.
I think it needed some messing with, Ron...at least for my taste. The mids are so out in front, the lower frequencies lagged. I added the wood on the bottom of the horn and then put a few pieces of closed-cell foam on either side of the horn leaving about 14sqin per speaker of port. It seems to have helped the bottom end catch up quite a bit. Bass drums are punchier and bass guitar licks are bouncier. The foam might be narrowing the horn dispersion, but it seems to sound great.
