Well currently I have a Altec Lansing ADA995 5.1 speaker set, THX certified, and it has 200 watts I believe. I kind of want to keep this since I bought it for just $10 at a yard sale and the sound quality is excellent, however I'm thinking about getting a 5.1 or 2.1 speaker set that has better sound, and also has a small subwoofer. The sub for the ADA995 is pretty much the same size as a desktop PC. Are there any PC speakers really worth upgrading to that are less than $130? Or should I just keep what I have? Currently I have my eyes on the Klipsch Promedia 2.1 speaker set or a Swan M10 2.1 set. I am using my speakers for my Macbook and PS3.
