When building a ported box for 2 subs do they need to have separate chambers?

That's not a good enough answer. No, they don't have to, but it entirely depends on the application.

no they dont..put its entirely up to you and your setup/preferences.

What type of application would two subs "need" to share or have a separate chamber?

I didn't say they needed, I was implying it's preference as there are rules on porting unseparated subs versus separated assuming you port down the middle.

I say yes and no. if you are gonna have 2 subs on 1 amp then no but if you have 2 subs on 2 amps then yes they need to be sepetare chambers

did you get numbers up for your wall yet? op, two will be fine in a a common chamber ported. ive never done different for dual sub setups ported

When you get into 6, 8 or 10+ subs with huge airspace, it probably makes sense to group them in separate enclosures of 2 to 4 subs max. There is some science behind why you should, but heck if I remember what it was.

I don't know exactly, but I can imagine it has a lot to do with keeping the cone controlled by the pressure, and if you are pressurizing an airspace that is very large with speakers moving at SLIGHTLY different times, the chances of keeping all of the speakers in phase with one another are worse than if keeping them in phase while pressurizing smaller air volumes. That is pure speculation, so don't take this as fact anyone //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Also, I think that if one is blown, the effective air space per sub is doubled, which causes to remaining sub to bottom out. I think...
