I am in the process of building my first sub (Shiva EBS 142L)and I am wondering if anyone who has build the same sub or another using the Shiva has attached a plate to the legs of the sub. Bascially, what SVS does with some of their boxed subs. Would this have any effect on the performance of the sub? Any input would be greatly appreciated. P.S. The box is built and ready for painting. I am waiting on the Shiva, the port tube and the PE amp plate. Hope it comes soon!
