Hi all, I have, what I hope is an easy question.... I have a pair of fully loaded BL 10's, So I am using WinISD to design a box, and I have some missing driver parameters: Pe: ????? ( I was assuming 1000watts ) Le: ????? Z: ????? Any help would be most appreciated! I currently have them housed in a 2.56 cu ft boxed tuned to 28.33 hz that I built for my previous cerwin vega v-max's, and the FI's sound really good in it, I just want to make sure I am not missing anything by not building a spec'd out box. Thanks!
