I am purchasing some speakers to use with my BlackBook and have narrowed down the choices to the Swan M10 and Swan D1080 MkII. I realize the former is a 2.1 and the latter is a 2.0. I am more inclined to the 2.0, but am willing to put the sub-/mid-woofer on my desktop. I would appreciate any advice regarding the difference in sound and function between these two systems, e.g., I am curious how much better the 2.1 will sound than the 2.0 (I have never had a 2.1 setup before). Also, why is the D1080 MkII more expensive? because of the separate volume, bass, and treble controls? Any other helpful advice regarding the two would be appreciated as I am learning about sound equipment only now.
