trying to find a new sub and these two are my alternatives so far.
the xls is the one i got now
its a sealed 0.8 cft box on all of those. dont really want to build a new one
dont know if it tells you anything, but probably more than it does me. i figure (im new to this winisd thing) that the two other are louder down to about 50 hz but the xls have a more even slope..

what i`m really asking is what to read from this.

First, make sure the program has the correct parameters input. Notice the inputs for Sd in the above windows, for example. The modeling won't be accurate until WinISD has correct information to work with.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

The main thing I read from this is it is meaningless if the T/S parameters shown in the three woofer info boxes is what you tried to plot. The data is wrong and incomplete. I suggest you re-enter all parameters and try again.

Looks like there is no difference worth talking about in any of those plots.

thats my thought to. its like if i insist on going with my 0.8cft box i could just as well stick with my xls.
