All- I have a Dietz 1x15 cab that needs a new driver. I have two choices, a EMINENCE DELTA-15LFA 15" LOW FREQUENCY DRIVER and a Celestion BG15S-100 (used in Avatar cabs). Any thoughts on these? The current EV15 speaker paired with my old school Peavey Mark III head and '83 Ric 4001 sounds way too middy/nasaly and simply can't handle the neck pickup, so it's gotta go. Thanks for your 2 cents.
