I am thinking of upgrading the mids on my 3-way horn system to a Volti FC260 tractrix, but am undecided on the driver. Many phenomenal systems have been built using the BMS 4592ND-MID (around $650 each), so that is a top contender. Much of what I read, and a little of what I have physically auditioned, however swears by Beryllium... which seem significantly absent from posts. Admittedly that was with Classic Audio Systems that had not only Beryllium but also field coil drivers Beryllium plus field coil is out of my price range - and it's impossible to separate variables. Looking at new Beryllium, Radian drivers look amazing... except for the prices: 760NEOBePB at $850 each, or the 950BePB at $1100. True, that is a big increase, but in the long run... in for a penny in for a pound. Three years from now I will have forgotten about the extra money. So... anyone out there have insights or experience on this? I am probably willing to spend the dough, but would rather not unless truly a significant step up. I tri-amp so efficiency is not an issue, and I am satisfied with all other specs.
Thanks.
