I am looking for a new sub, Ron advised against the pb-10 because of the size of my room 26L x 12W x 8H, with no major openings. I listen to movies exclusively, and looking for the right sub for my system. I run Def Tech up front w/ bp10 towers and clr 2002 center. I am looking at the 20-39pci, and think the 20-39 plus would not be necessary for my needs. I am trying to justify the the extra $250 for the plus vs. a solid pci in my price range. I would love to hear some opinions or testimonials of experienced SVS owners who may save me some judgment errors. I would like to hear the opinions of other enthusiast's, your input would be greatly appreciated.
