Question

measurement for a ported single 12 inch subwoofer box

Answer 1

Wish I could help you more than telling you to find the documentation that came with your speaker.  I did a web search and the only thing I could find on that brand was an eBay listing.

Answer 2

i have searched for about 15min. for info on that company and i cant find their company web site (or any site that sells that brand other than EBay) so, I would not waste my time, energy, or money on building a box for a low quality sub like that

Answer 3

powerbass is not low quality by any means. i had a 15" extreme....extremely well build sub. 2000w rms 4000 peak weighing in at 46lbs!

couldn't have search for too long....http://powerbassusa.com

without knowing the model you have i can't say. however i do design costom enclosures. let me know the model and i can help you out.
