and would the atlas work better in a ported or sealed box i heard the guy from the company who makes the atlas recommeds sealed? but im really looking for spl so what do you guys think
well for a 15" the Atlas is incridible for sq, but like any 15" it will be capable of getting extrememly loud. i would say it leans more on the spl due to its size but for a 15" it kills in sq as well. go sealed, all Atlas subs are recommended sealed, i wouldnt give up some sq by porting it. it will be loud enough sealed.
