In October, I will be upgrading my system with an Outlaw Audio 1050 receiver. I am looking into adding a pair of dipole side surrounds to compliment my monopole rear surrounds for 6 channel operation. I have a couple of models I am thinking about and I welcome any advice about whether one may be better than the other or if I should be looking into something else entirely. So far, I have come up with the Atlantic Technology 350SR and the PSB Ambient I speakers. For the AT's, they are THX certified, have a slightly larger tweeter, each speaker is heavier than the pair of PSB's together (better, more solid construction?), and can handle a bit more power. For the PSB's, they have larger woofers and are "quasi-dipoles." The woofers fire in phase while the tweeters are out of phase. They are also a bit cheaper than the AT's. For my criteria, I will not be listening to multi-channel music (DVD-A/SACD) anytime soon. My room is small (roughly 12' x 20' apartment living room) and they will need to be wall-mounted. My current speaker set-up is mix and match so I am not dedicated to one brand/series yet. Finally, the price must be under $400 for the pair. If needed, here is a rundown of my speakers: Fronts: Wharfedale MFM-7 Center: Infinity CC-2 Sub: Phase Technology Power 10 Rears: American Acoustics Labs large bookshelf (free speakers ) Any comments or suggestions for the new speakers will be greatly appriciated.
