Ok I'm going to build a center console box holding 2 Sa-8s. But I need help on porting this thing. I have seen these thing mostly with the tube ports, how do you tune these? I will be doing some thing like this (link below).

Help me plz!

that?

 

The calculator that DBfan posted will work just fine. You can find all different ones on the internet, but they all work on the same principals of physics.

But I just wanted to add, it's always a good idea to talk with the speaker manufacturer, or one of their tech guys, and ask them these questions 1) what is the "optimum" cubic footage recommended for these subs, 2) what is the best tuning frequency for these subs, and 3) how many sq inches of port are recommended for these subs.
They might ask (if not, you should probably just mention it anyway) what kinds of music you listen to the most > because these "optimum" numbers can vary a little, depending on your musical tastes.

With those numbers at hand, you can then pull up one of those calculators like DBfan posted, and build a box that is "spot-freaking-on" and wow all your friends like your a pro Easy peasy

Peace,

Thanks guys! That was exactly what I needed running a little low on funds, personlly thing at home. But I will keep you guys in mind. And if you guys run across any ported box designs plz post them. Thqnks again.

 

How much overall space do you have? The SA-8 needs up to 1 cubic foot per sub. Depending on tuning frequency. I have an SA-10 and they're power hungry and LOVE larger enclosures for ported.
