Hi Guys,

I have the above speakers and a pair of replica A7 cabs made from very good grade plywood to the factory plans.
I have a pair of 811B horns....

My question is about the X-Over frequency - should I go for 800 cycles or 1200 cycles?

If I buy a pair of 511bs will I be able to use the 902s at 500 cycles?
I have a brand new pair of GPA's replacement diaphragms installed in the 902s

Thanks

Winders
