You know, if there's one thing I would like to have burning it would be my pocket haha. Well perhaps you could revisit your options at a later date. I personally won't ever go back to one sub but placement and funds usually interfere. Fortunately you don't have a slouch of a sub now so enjoy

Re: Mixing Ported Subs with Sealed Subs in a HT?

Hey I know this post is a bit old, and my advice may be of no help now, but I have actually tried mixing sealed and ported. I have a ported 18" and was running it with a sealed SB-1000 with the intention of using it to hit the low frequencies my 18" could not and, in short, it should not be done. At the time I did not have measurement tools for a Frequency Response graph, but I didn't need one to hear that it didn't sound right. I had the SB set at the rolloff of the 18", which was about at 50hz, and tried multiple different placements and phase settings between the two subs. In the end I gave up and sent it back for the ported PB-2000, which then didn't have as much punch as I was looking for, then I bought the PB13 Ultra and now I will never look at another subwoofer again because this on takes the cake and adds perfection to my sound.
For what ever reason the difference in tuning between ported and sealed boxes noticably creates too many nulls and peaks in frequency response of the overall bass. I strongly advise against it.
