I'd like to design as small an enclosure as I can for this driver to fatten the low end on my rig. I've downloaded Winisd but can't seem to get anywhere with several issues...access violations when closing the program, no help file installed, after adding the driver to the database I can't select it....etc. I don't have a lot of power to give, running an older Eden Traveller that's 400 watts at 4 ohms, or an MB200 which 200watts. I would be running that speaker, as it's 4 ohm, alone with the MB200 or under an Epifani 112 with the Eden. Don't really know what frequency to design for, I play 4 string but use an octave pedal occasionally.
