Neo magnets do not have as much inherent distortion as the magnets in the RBH cabs. They are a bit cleaner. But some people like the grind of the RBHs, look at Duff. The RBH speakers were designed by GK and are made by Eminence I believe whereas the neos are designed and made by GK. The RBH cabs are louder than the neos in the sense that a 410 RBH has a higher sensitivity rating than a 410 neo...but the neos are still pretty dang loud

I have been dying to get my hands on one of the RBH cabs but they just don't come up used as often as I'd like. I have a neo 412 and love it.
