Bottom end, sealed dual 10" vs ported dual 8"?


This may be an impossible comparison but I am trying to compare what I have now with what I may buy on paper. I currently have dual 8" subs built into my tower speaker (powered) and ported. I am looking at going a different direction and moving to dual 10" subs (powered) in a sealed enclosure. The question is with the rest of the system being equal how will these compare?

Thanks

I don't mean to sound negative, but there's no possible way to make that comparison. There are so many more factors to consider, the comparison of (Bottom end, sealed dual 10" vs ported dual 8"), is not relevant. The only way to get anywhere in this situation is to just try different equipment next to what you already have. Bass is always difficult to get right and there is just no easy way out.
