why not do a few less subs and give them the recommended airspace?heres one idea... waiting to see what robin comes up with. this is one of the plans Mobeious came up with. 18 12s sealed, roughly .8 per sub.
still not sure if i wanna do more subs, sealed
or less subs, 4th.
this does look BADASS though, and will look even more so with a mirror at the end of the tunnel!
