Using 2 Subwoofers

I'm going to be a bit contrary. I have a similar sized room and it is also open on one side. I have a JLf112 that I placed in front just inside my right main speaker in a position commonly recommended byt JL , THX, etc. I ran the JL equalization and the pioneer system and decided the JL system resulted in slightly better performance. I have on several occasions tried listening in all areas of the room and while I can hear a difference, in my case is is not huge and frankly no big deal (YMMV or course). I would suggest trying one and seeing what you think. Than again I also find that not having a matching center ( I do, but ran non matching for some time) was less traumatic than I thought it might be.

I own two 15" non-ported audiophile subs and have them placed on either side of the room. One in back and the other in front next to my towers. For two channel music I turn off the sub in the back, because I prefer all the sound coming from in front of me. For movies both subs are set to levels that make you feel like a neutron bomb was dropped on my house.

Therefore, I recommend two... you can always turn off the second one.

I use 2 JL F110's in the A/V room - and I can say that 2 subs sound a lot better than one. The overall response is smoother - there is no localization - and it's a huge presentation - Just a solid Wall of bass - One is good but it looses that magic

Dovjm, I have a SVS PB13 Ultra in a room really close to yours and it works extremely well. 14x19 roughly with 1 doorway and open to dining room on other end. I keep the volume at center on back of sub and my pre measures from -15 to +15 and that's set at -9. All other output settings within sources are center -0-. I recommend the SVS....Bob Reynolds recomended it to me in one of my forums and love it. Thx Bob....
