I have a friend who is setting up his first HT. I tried to get him to buy an SVS (PB2+), but he is "anti-internet" and I can't change his mind. He has a LARGE room - 18' X 33', but they are not bass fanatics. They primarily watch movies in this room. This will not be used for audio. Now for the request for help. He wants to buy from Tweeter due to purchasing some Denon AV gear there and Polk and Velodyne are the primary brands they carry. Can anyone give me personal experience on Velodyne DPS, DLS-5000R series versus Polk Audio PSW505 and LSi/W or something else Tweeter caries. Main Speakers are Polk Audio RTi10, CSi5 Center and FXi5 surrounds. Thanks for your help.
