Do you think you need a subwoofer?

It's kind of a joke as our living room is 11'X12",and yes that was my point.i tend to buy the best I can(to enjoy),and hopefully this year we'll add on or aquire a bigger house.
i know my system would love more breathing space,I can only imagine what she'd sound like in a bigger room.The room does give me some idea of what to expect,perhaps the calm before the storm.

For me as our living room is really big(11X12)I was hesitant in trying 2 subs.to some folks I might do things backwards.
in four years we bought a 900sq.ft. house,and of course I love audio.So I have been buying gear suited more for a bigger room.My speakers are revel 50as,Bryston 28B-sst+7B-sst+1X4Bsst,2XDD-15 subs.One which I have been using just for the .1 for movies.Raul suggested trying the 2 in stereo.
As I don't have much room I tried it in front of my speakers.One sub was good if you were sitting where I was sitting.Using two in stereo solidified the bottomend(Way more) and gave me way more soundstage depth,almost a 3-D effect.I imagine some are thinking,two DD-15s in a 11X12 room.And why i am I not using satellite for mains.the revels put out a nice bottom end(stereo direct)But adding a sub makes it way more solid,like a we'll recorded kick drum or bass guitar.adding two just makes it very enjoyable(more like a live event).I have no boominess,bloat,no nasties.I could only imagine when we add on to our house or buy a bigger house,how much more I'll get out of her.I thought two subs
might be too much(quite the opposite if you listen and be patient when adjusting the subs).I do Y cables out of my R+Lpre to amps and subs,speakers set to large.I have the subs X-over at 64 hz,as my speakers supposedly go down to 32-34 hz.I will try the X-over at 80hz and see.I like where their at now,very emotionally musically satisfied,BUT.Anyway it was a great surprize integrating the other sub,only one problem,I need another sub for my movies now,Thanks Raul.
