Hey, new to the forum and this is my first post. I'm looking for some advice for a subwoofer. I just started building my system and I got great deals on my towers and receiver. I'm in the process of looking for a subwoofer that is powerful enough to go with my system. I have heard the RSW-10, a friend of mine has one and it sounded great, but with smaller speakers. I'm worried something like that might not be enough for my system though. With my mains being the KG 5.5 and surrounds Epic Series CF-2, I'll have plenty of bass for most, but the wife and I love a lot of bass. We will use this system for both home theater and music. I saw the SW-311 has dropped in price tp around $600 and that's about what I want to spend for one that size. Do you think it would be enough to keep up, or would it take 2 of them? Should I go with a RSW-12 or RSW-15, or even a RT-10D or RT-12D if I can find one? I want to keep to Klipsch and not really trying to build my own. I figured the RSW or RT series would be the best but they are harder to find. Any suggestions as to what a good match would be? Thanks in advance for any input.
