Stereo Subwoofer Pairing

Followup question on Rel's specifically.  Can I use a new i edition of the T series with the old T series?  Or are the model changes major enough that they won't sound similar.

That would be a question best answered by REL.

I asked rel.  I'll post their response here.

rjb1101,

     If you set it up just so, you could become the first human in the history of our species to be able to hear deep bass in stereo.  
     Where'd you get the idea that stereo subs would be a good idea? Or even discernable.  
     Sorry, stereo deep bass is a myth so it's probably best to keep your expectations very low to avoid the inevitable disappointment.
It's not too late to save some time and money and abandon this nonsense.

I'm not expecting to here bass in stereo.  I just want a dedicated speaker per channel input so that the signal doesn't overlap.  A speaker can only play one analog signal at a time.  If you input two signals the speaker is only playing one of them. Whether it is a digital or analog summation of the two signals, I would rather have a 1:1 input output of the bass signal.  Even if it isn't a huge difference.
