Alright, I was looking into the Shivas, but I took a look at the BP 1202 series, which I am not sure if its out yet. I want to know how the Shiva compares with this BP 1202. I am looking for SPL this time and am also considering the Tempest. Out of all these subs, which would get the loudest in about a 2.5 - 3.5 cuft. ported box. Thanks.
