Well this might sound dumb but what is the "ranking" of Alpine subs? I got a friend who wants to sell me two 10" Type E's in a custom ported box with an amp, etc. He said the ranking was S, E, R, X. But the Alpine websites pricing shows that the least expensive is E, then S, R, X... So is it worth it or no? He wants $400 CDN.
