New ppi subwoofers

I was going to get 4 of them until I found out they could only be ran sealed. These subs are not made to work in ported applications at all!
Well the 10" version has a Qts of .65 where the 12 has a Qts of .92. This indicates the 10 would be better suited for sealed, and the 12 better suited for infinite baffle. But again I have to question those specs, as I find it odd the 10 and 12 have such vastly different specs. Very unusual.

In many aspects, they're flawed designs in my opinion. I've played with them when they were first available. I don't remember anybody being very happy with them. Maybe that's the reason why they're blowing them out really cheap.
