"And just an FYI the Boston Acoustics BA-4800s are a far better 4.1 set than the ProMedias."
Well, here we go again. Actually, anyone who knows speakers really well will tell you that you should listen to speakers before you consider what is the best. Choosing speakers is a very subjective thing, and to get a set just because someone else said they are better is not the best choice in my opinion. I have had both sets and I sent my BA4800's back once I listened to the Promedia's, they were just on another level to me. I wish I had listened to both first instead of just buying one because some people said they were better, it would have saved me a bunch in shipping sending those BA's back. It depends on how your ears like the speakers, and the same set of speakers will sound different to different people and in different locations. I am gonna pick up a set of the 2.1 ProMedia's and pair them with my 4.1's to make a 600W 6.2 set-up. Noriaki, this forum is for people to hear different people's opinions, if your opinion doesn't agree with mine or anyone else's, that's no need for flaming.
