I got it from the local huge store, Neb. Furn. Mart. But I assume they will be showing up everywhere now. The sound is basically what you would expect from speakers that size. It's a knotch up from the build in speakers that's for sure. Without the sub I'm not sure how much better it would be from the build in speakers, still a little I'm sure but it's amazing how much the sub adds, I think the cutoff might be a lot higher than the sub that most of us think about with that 'name'. I guess what I'm trying to say, it's a little more than a sub woofer I think. I must say I really do like the HDMI CEC for this and the BD player. The wife likes it too, she actually figured out how to do netflix instant on the BD player on her own. Everything just works including this SB with on/off, volume and auto input selection from any of the remotes.
Oh, I about forgot: On the wireless interferance, it does work great, just make sure you have you wireless device connected before you turn on you SB. If you do that the sub (or SB) sees the frequency is in use and automaticly picks from one of the three frequencies it uses that is clear. If you turn the sub (or SB) on first and then your wireless you might hit a used channel. Anyway, that works, at first my laptop didn't connect but when I fired it up and connected, then fired up the SB, I had a 54 Mb wireless connection.
