WinISD and boston acoustic 4.5" woofers??

[gadgeteer123 21]

This may sound a bit noobish, and it may be.. But I am trying to enter these boston acoustic 4.5" woofers into WinISD, and it keeps saying it fails in many different areas,so am I entering something wrong, or are these bogus specs on these woofers? These woofers do sound good for $15, but I think the specs listed may be wrong please help me? Here is a link

If you have the new winISD alpha, it is very specific in the order in which parameters are entered. Go to the help menu and read the tutorial on the order of entering parameters.
