I have two PXW1252 12" woofers. I'm not too sure whether I should make a sealed box or a ported one. In the past I've preferred ported boxes, but I think these subs are more for sq then spl, although I could be wrong. If a ported box, what would you suggest I tune it too? And tube ports or slot ports?

 

3.5-4 cubic feet after displacements @ 36-38hz

 

absolutely unequivackly without any doubt....ported. For box size and tuning though..what vehicle these going in?

 

They're going in a explorer...

 

then Jalat's reccomendation is pretty solid.

 

Alright, thanks alot.

 

One more quick question.... should i have it as one big chamber or split it into two, one for each sub?

 

Either or really.. 1 big chamber with some bracing is easier to tune

 

How's that look? I found it easier to tune with 2 seperate chambers. If I did it correctly that should be 36.5hz, and each chamber 1.85sqft. Let me know if this is correct please, thanks.

 

Haven't confirmed the tuning but those subs do love to be ported.....looks like a solid design to me.....
