Well guys, last night we were able to do the experimenting and finally some clarity. Running that Peavey 22A original driver for the MF1-X horns did the trick, results were far better than with the Selenium D220ti driver. We got all the frequencies of the super tweeter, we were amazed that the 40 year old 22A driver would give that performance so this issue is now very firmly settled.

Here's the thing however, we had run the system back to back through both the Rane Ac23 and the BSS Processor, it was through the Rane that we were able to get that performance out of the 22A while the BSS far outclassed the Rane on the bass. The next and final experiment hopefully on this coming Sunday will be to see if we can get the BSS to get the same performance from the 22A driver.
