Let me get this straightNo their dead easy to fit, just take the back of the pc and plug it in, although I must admit that great bunch of wires sticking out the back had me flummoxed! had to get our keyboard guy to hook everything up.....that was last year, still cant understand it all!
Just for listening at the moment I think I'm a long way off making my own musicJeanette, it all depends on what you want to do with your PC. If you just want to listen then go down the 'Bose' path.
If you want to get in to making your own music then 'powered monitors' are the way to go. As for cost, that's up to you.
