How come there are no sealed recommendations for the Death Penalty series? How will they sound sealed? SQ and loudness wise....

It's not because of SQ, it's for the same reason the DR is ported only, it's because the sub isn't designed for sealed. Can it be used in a sealed enclosure, sure. It's against IA recommendations, and most likely will cause your warranty to be void.

My DR is ported and still sounds wonderful. It's all in the enclosure.

Is this for listening to music, or competing?

Daily: just going to say 30hz so you won't miss anything on those bass cds, rap, and so forth.

SPL: Your going to want to do some testing, otherwise try 40hz or so.

Broad answers here.
