I plotted out a box design in winISD, and I went to the cone excursion plot and I'm checking out some different subsonic filter settings, its a 4cu/ft box tuned to 30hz and my main question is, can I use a 25hz subsonic filter as long as the excursion isn't exceeded? When I plug in a 25hz@12db the cones hit about 20mm out of 28. Physically I see that it may not bottom out(afaik) but will it just sound like crap?
On the higher end the cone excursion seems to be peaking at 43hz, and its at a nice low dip right at the tuning freq of 30, the lower you go it starts rising back up again. Without any filter I will have some issues around 23hz. I don't think I have any programming that exactly goes that low but I'd rather throw a cheap hooker audio or harrison fmod filter on it and not worry about it. My amp doesn't seem to have a subsonic filter on it(zapco c2k 9.0xd)
Thanks,
