I've finally got a second pair of B200s on the way to augment the pair I currently drive with my Sig 30 in open baffle. I'm pretty sure I remember a couple people driving the speakers in such a setup (3ohms?), but I can't remember if you're supposed to wire them in parallel or in series. I plan on using an inductor on the lower driver and running the top driver in full range (as I now do). I know at least a couple of you out there can shed some light on this small problem, so thank you in advance : )
