A couple of years ago I bought an Onkyo HT-S3100 htib. The receiver that came with the package is called an HT-R340. Now I'm thinking about upgrading the main front L/R speakers. I'm mainly interested in music (home theater is just a bonus), and the baritone range is what I feel like I've really been missing, so I think I really want floorstanding speakers. I've been looking around online and thinking something like Polk TSi300s or something in that price range would be a good bang for my buck. But I'm not sure if the receiver I have has enough juice to really take advantage of them, perhaps along with the three remaining Onkyo satellites, to produce undistorted sound at a semi loud room filling volume level in my 13' deep by 17' wide room. Help?
