Well, all of those plans might have to go on hold for a bit, or sort of mold around other factors as eD has limited stock of everythign left. if I were you, I'd keep an eye on what's coming up on their closeout page, and grab one when you can. Asfor the exact sub choice, why 10a? unless you're feeding it 1kw of juice, you can easily do just as well with less. I almost in a way wish I'da just gone the 10o route myself, just at the time they had the tsunami amps on such a deal I couldn't resist, an then, of course you can't have allthat power and not use it... *sigh* it's a sickness I tell you... Honestly, though the 10o's are supposed to be wher eit's at for top SQ. Oh, and on the fiberglassing front, if for any reason you want yet another take on it, I'll try to do a littleblurb when mine's complete. sofar I'm sill constructing my wood bits (Sucks being at the mercy of friends for access to tools) I did some styrofoam peanut testing today, and from that, it looks like my 12a will be WAY less intrusive than I'd previously believed. I'm pretty sure yu could tuck a 10 in VERY tightly. As far as price differences. I don't really thingk the 8a is quite the same animal as the rest of the a family. dramatically less power handleing and such. And what he's talking about with the box building is being able to incorporate the needed port to make the "big8" work. since they reccommend it for lots of power, and ported applications only. I'd really jsut stick with a sealed box for fiberglass. My idea was to fiberglass my box, then run a port along the floor, but that's just a bit too involved at this point. Maybe later on down the line if I ever manage to think JUST 1100w in a sealed box isn't enough
