Oddly my Neo cabs (EBS) are a little mid-shy, and to get any honky-ness I have to EQ mid into them! The total opposite of your soundchap's takes on Neo speakers! Maybe my ears are shot as well.
From whats been said it kinda sounds like he's an old-schooler who knows, loves and trusts the big fat warm old speaker sound… most modern stuff sounds sooooooo different to the old Peavy, Trace, Orange tone that most engineers face day to day and become familiar.
I've had a few engineers tell me how 'odd' the EBS Fafner sounds… which is crazy, as its clearly the most amazing amp ever made ;-) Its just 'unfamiliar to them'.
If he hears too much mid. turn the mid down! Don't change your rig!
