I'm basically asking only the people who have/had them and had them in a box. Opinions?

Thanks mike, i was going to do that size and tuning. The customer has a za2500.1 where the subsonic filter is fixed at 25hz... You think the sub will perform just fine with the port at 32hz and subsonic at 25hz? Im assuming it would be just fine since 5-6hz below port tuning is considered best (and since very few songs, if any play below 25hz) opinions?

SomeDonnieDude Gold Member Username: Somedonniedude Illinois Braaap MX Post Number: 2759 Registered: May-07	Posted on Tuesday, August 25, 2009 - 19:10 GMT 24db per octave @ 25hz on the zx2500.1 Hope that helps someone answer this question, if that's the amp.

Most guys if you explain the sub will damage playing below f3 they will be more carefull
