Can't imagine what that sounds like having (2) of these kickass subs! >>
It would sound like a huge marketting gimmick and a rip off

With the 4.1s all the bass from the front and rear channels get used anyways, so it's not like you are losing rear bass. And bass in fairly non-directional, the huamn ear isn't capable of associating direction with very low frequencies. If you happen to get bass blasting in the front and rear at the exact same time it would probably get a bit louder...but in most cases you'll have an explosion in front of you or behind you, so only sub will really fire, and since you can't really directionalize bass it won't really matter to you.
You might get a little more direction...I don't think the Sats can go low enough to get past the threshhold where you can't directionalize the sound...but for the most part the 2nd sub would not be of a huge amount of use. Cool for bragging rights...but that's about it. If you consider that in home theatre setups you just take the sub and chuck it behind a couch or in a corner or something....it's because you can't tell which direction it's coming from.
It's nice to see them working on the mid range on the ProMedia's, that has always been my biggest gripe with the ProMedias is that the midrange was weak....
Now, if only they'll come out with a 5.1 set with an external AC-3 decode
