That is correct but I need to add some additional measurements based on the filter settings, etc. just wanted to make sure that I mentioned that. I should have those up later today or tomorrow.

Dale, can you repost the Frequency response and Max Compression charts for this sub?

Knowing that this sub is not a SPL monster, how does this sub compare with other 12" driver subs?
