I have heard of people that have been able to dial in a sealed sub with a ported sub but it is not easy to do. What will happen is right around tuning of the ported sub, in this case around 20 hz for the Cap, you will have issues with cancellation when you add a sealed sub because of phase issues.
This means you will have a lot LESS output in that freq range, not more.
If you have measuring software (omnimic, REW, etc.) to see what's going on and then something to tweak the subs like a minidsp then you would have a better chance of figuring out how to dial them in together but I've heard it's not easy.
If you have 2 sub outs (true sub outs with separate delay settings for each sub) then maybe you could get away with not having to get a minidsp or something else to adjust sub distances separately.
Also (and I'm not sure about this just guessing) I think that even if you dialed them in at your primary listening position you could still have cancellations in other areas of the room. Like I said, not sure about that hopefully others can chime in on that.
All that said I'd still be tempted to try it out!! Edited by carp - 4/4/13 at 5:43am
