Impact of parallel drivers on T/S parameters

[Paul Ebert]

This has probably been covered somewhere (for which I apologize), but I haven't been successful searching. My question is how T/S parameters are impacted by using two drivers in parallel. The parameters I think I know are:

Re - divided by 2
Sd - multiplied by 2
Vas - multiplied by 2

How about the others? It seems to me that Le would be divided by 2. I do not know how Qes, Qts or Qms would be impacted, nor BL. And, do I keep Xmax the same?

Thanks.

There is a short write up on my site, under the General Speaker Related Articles page, that shows how to model two drivers in parallel or series.
