I have a pair of Electrovoice 12 TRXB's in some beautiful cabs, with vintage McIntosh tweeters as supertweets...I removed the backs of the cabs and that improved the presence of the trxb's quite a bit.
Now, I have a chance at some Tannoy D-500's...
I wonder if its a definite upgrade??
McIntosh MC40's managed by a Berning TF-10 is the main hardware.
