Every spec in red is different.

And you can read the discription with each sub.

yeah they are different but not by much. I would think the only one that makes a difference is the xmax. This is just me thinking out loud but if you were deciding between the two the xmax would be the deciding factor depending how you want things to sound. In my case I have 2.8cu ft and an AQ 1200d running a single 12 makes things a little difficult deciding between them I know ill most likely go with the ssd. Im just trying to really understand the two and thier prices.

Read the book Loudspeaker design cookbook by Vance Dickason and you'll understand what is important and what isn't.

(spoiler: everything is.)

From what I understand the Q subs are low end subs that move tons of air. If that's what your looking for them go with that.
