PS do not forget to check out the size of the box you want to install.
your small room will make those you listed look real big when you
put it into the room. the dimensions that they are and for the most part
you do not want to put the sub woofer next to the wall.
as I said the sub sounds are omni directional, you hear it through out the room
and not from the speaker. subs need space away from the wall to sound good.
(check with the sub maker and their recommendations for the install space distance)
try some cut out paper/cardboard and see how much space it will take up.
I ran a 12" bic $200 430 watt peak sub and it shook my walls, couch and during inception it even
looked to move my wooden sub floor 1" during one of the passes.
my room was 13'X16'.
your larger and more powerful choices might be able to break down a house.
you also might check in your area and see if some followers of AVS are going
to have a local meeting. they might have a sub you can audition.
just trying to help...
