[QUOTE="mrogowski, post: 3680026, member: 569061"] WinISD (or any program for that matter) will not be able to tell you the sonic signatures of any driver. What it does show you is how the driver will act, or react, when placed in a certain enclosure. Some things to look for when using WinISD on a driver would be excursion, impedance and vent velocity (if you were doing a BR enclosure). SPL output is hearsay since the environment will play a big factor in total SPL output. Many folks here will tell you that using WinISD is wasteful when trying to determine designs for vehicles. While much of that is true, WinISD will provide you at least some basics or guidelines towards building a box that better matches the driver. On a personal note, I would lean towards the purple line myself. At least in that box size I'm fairly certain I would get the lowest bass output from the bunch. [/QUOTE]
