Went ahead and picked up a 2240 to get started- not too expensive and I know it can be later re-coned to a 2245 should I require something that goes lower. I like the Idea that the 2240 may be punchier and more dynamic- and do not see the need to go below 30hz and there is room loading to consider and we have a lot of glass windows/doors here...

Room size is roughly 22' x 16'. Main viewing/listening couch will be about center- 11'-12' from the screen.

Sub could go in front or behind of couch- probably a rear placement would have more room/out of the way.

I understand a ported 8 cu.ft. enclosure with a 6" port diameter is a good place to start.

Was also wondering if it makes sense to have the port down facing to load the floor? Would this room size really require two subs?

Any thoughts would be most welcome.
