ok guys I know nothing about these drivers other than they seem well regarded on here and they are reasonably priced. I have just purchased two to use in open baffle, possibly as stand alone subs and maybe later in ob with two 8" full range drivers I have, that I have no parameters for but have been told will be excellent in ob. I would also use a tweeter, so 3 way in all. But for now I would like to know what size baffle would be best for these drivers as a pair of subs cut off about 100hz. Also what would I need in the x over.
