ST33M Posted May 22, 2008 Report Share Posted May 22, 2008 No program is accurate. Only real world testing will give you that accuracy. Winisd is pretty good to get a base line for the starter box and tuneing. Seems to par with bbp6, but without some of the options and features bbp6 has. much more user friendly then bbp6 as well.

banginAltima Posted May 22, 2008 Report Share Posted May 22, 2008 WinISD is very helpful for getting your port length/freq. It gets you in the ballpark. I think winisd alpha pro is the best one to use. If you build it, db's will come... NSPL World Record Holder Trunk 0-1800 watts---147.9 with 1722 clamped watts @ 40Hz(9-20-09).
