SpeedGod,
If these are the only two you are considering between then you don't even have a hard choice. The BA4800's are the best multimedia speakers available, especially under $200. I don't want to get into the Klipsch argument with anyone, so please don't even start that in this thread, they cost $250, the BA4800's cost $139. For the price the Klipsch don't even compare. But back to the point.
Boston Acoustics has been making home theatre products for over 20 years now, a company that's been making multimedia speakers exclusively, for only a few years, simply CANNOT have the same level of product. Not to mention Boston Acoustic's customer service.
Don't believe me about their customer service? Check out
this thread.
Multimedia speakers should be an investment, just like your computer, something that will last you for years to come. Spend an extra $20 on the BA4800's, these speakers will surprise, if not amaze you. Bestbuy.com has them for $139 + shipping, and I've heard outpost.com has them for $150, with free overnight shipping.
