One thing I've noticed is that when you turn up the treble, it sounds more like how ferrite drivers have sounded to me in the past. More rounded, not harsh, and can get that little bit of growl or .....almost compressed and distorted in a good way, the way a bass cab should sound. Every other neo driver I've heard sound too clean. Good but, too clean. Maybe Im not describing it correctly but, whatever is going on, it makes me excited to play. Im sure that it's just the voicing of the driver. Alex did it right. I can say without exception that this is the best overall sounding and performing bass cab driver I have ever heard. I don't think anything else has been even close.
