Has anybody ever tried placing 2 subs (not isobarically) in an enclosure, sharing the airspace (ie 1 shared chamber for both subs, mounted regularly)?
My initial thoughts of this is that when placing 2 subs in a shared enclosure, it probably changes the characteristics of the sub, making the box size requirements different than the manufacture provided specs. Is this correct?
when u have 2 subs aharing thesame air space one of thesubs becomes what u call a slave to the other. in other wordsthe strondger sub will be more dominant and hinder the performance of the weaker sub. thus u will not get 100 percent performance which is alwayss prefered. In some cases the difference is very noticable and in some cases it may not.
What do you mean stronger sub? What if both are the same subs, driven by the same channel on the same amp?
Just make sure that you give the subs the space they require. So if the subs require 1cubicft make sure you have two. Otherwise they won't sound right.
What delta737310 was refering to is imperfections in the subs. If you have 1 new and 1 old sub, odds are that the new sub will perform better than the old (not gospil, just an example!). Even if you buy 2 identical subs at the same time, imperfections in one sub will cause the performance to differ from the other. If you place them in the same airspace then the stronger sub will hinder the weaker one. I've always heard that it was a good idea to use seperate chambers for best overall performance. That way each sub is only hindered by power, size, and it's own imperfections.

1) generally, not good to share a chamber
2) if they share the same chamber, the total space required is still the same as the total space in 2 independent chambers
.. hm.. if #2 is true, then, it really doesn't make sense to share a chamber (you're not saving any space).
I guess what I'm looking for is a way to save space while using 2 subs.
Need some info to help you save some space. What kind of subs do you have( model #) and what type of enclosure and volume do you plan on using.
I have 2 12" Orion XTR series 2 subs. They require 1.5 ft^3 / sub in a sealed box, 2.5ft^3 in a ported.
I'm planning on only using 1 sub in a 1.5 ft^3 sealed box, unless somebody can suggest a way to use both without causing too much of an increase in space.
