These are the three speakers I'm looking at. I want a plug and play 2.0 set that can be moved if need be. I cannot fit bookshelves with an amp somewhere otherwise I'd do that. I essentially want a solid set of speakers that will last and sound good. I currently use Bose Companion 2 speakers that I got second hand and they have worked wonderfully. Anything that sounds better than those will make me happy. Thanks! Note: I need a new set due to audio fluctuations on the bose speakers. Thought it was driver based but every effort fails. Only happens on these bose speakers. Any advice is appreciated, thanks!
