Hello out there. Quick question about my home theater room. I have a room that is 18x11, with a open 4th wall that goes into an identical siz room. All my speakers and subwoofer is in the one room, and I was thinking of upgrading my sub. I use the Energy 5.2 system with their 8'sub and a 10'Kenwood sub, and was going to go with a Svs model. Perhaps the 25-31 pci. The gentlemen at SVS said that I need to take both rooms into consideration when buying the sub, and the 25-31 wasnt big enough. Which leads me to wonder about closing off the room. So, heres the qustion!! Spend the money on a bigger sub, or close the room. Any thoughts? Thanks alot!
