I was looking for some opinions and advice on a 2.0 system and an additional subwoofer for my PC. My soundcard is an x-fi hometheater hd. I'm considering getting a set of Aktimate micros and a Wharfdale Diamond SW150 subwoofer. Will this combination work with my sound card or should I consider something else? I was considering the AudioEngine 5+ and the S8 Subwoofer, but I gather they possibly aren't as good? Also should I look at SwanM50W 2.1? Cheers.
