I recieved the 5 speaker set (4100) today and I love them!  Many of the other reviews mention the lack of rotary volume and the fact that you must adjust the bass on the back of the sub - well this IS NOT TRUE!!  I REPEAT NOT TRUE!!  At least on my brand new 4100 set the volume, bass, and treble are all rotary controlled from the desktop control module!  This was my only apprehension in buying the set, and now finding the rotary control on the 4100 my happiness is complete! So if you are thinking about some new speakers, get the 5 speaker set Altec lansing 4100!  Top quality!
