Hi Dan, thanks for the reply, there is virtually no baffle to model as I am trying something similar to Bjorn's no baffle. Also I have no parameter information for the 8" full range drivers I have, although they sound stunning until I get them going and do some measurements I won't know what may need doing. I am thinking about getting a Behringer crossover for the bass in stereo and seeing how that goes first. The Behringer CX2310 will do high or low so I can make use of it elsewhere if it doesn't work out. Once I get started cutting the " baffle " I will post some pictures, all will then become clear.
