Good trade. i myself prefer the 511b. examine your 511bs carefully and note whether or not it is one of the later models. the later (and to my ears better) ones have the "vanes" in the horn pre-cut and the gap filled with a rubbery like substance. also, a very small brace way back in the throat is absent, but the mounting spots are there. these tricks go a long way towards eliminating the ringing effect. If you have the later models, they can benefit by being seperated with a sawsall and the slot filled with silicone or rubber. Also knock out that pesky brace in the back of the throat. what sort of drivers did you end up with?
