Tuning depends on the sub, and the port size. Tuning lower will give you better SQ(sound quality), tuning higher will give you more SPL(sound pressure level, ie loudness). Different subs are for different kinds of tuning, some are made for spl, some made for sq.

Tunning does not depend on the sub...

The box's net volume, port's surface area, and ports length determine the tunning of a box.

Use this as a basic guide to port tunning.

you want to build a whole new box. Ports are pretty simple. They're just pipes stuck into the box. Unless you'd like a slot vented enclosure, but I just prefer tube ports because theyre easier to make.

Wouldn't the different t/s parameters of different subwoofers determine the size and length of ports? Or does it just affect space inside?

Don't do that, just build a whole new box, first off, your box is probably way to small to make ported, and if it's not it's probably not the right size you would want for that subwoofer ported...

so if i had a 12 w3 it would make it louder if i got a ported box

If the box is built correctly yes. If it is someone that just drills a hole in a sealed box and places a tube in it...most likely not and it will sound like ***.

Yes the difference from a sealed to ported box is generally 2-6db(night and day to your ear). So if you build a proper ported box it will be much louder.

if you are new to this maybe you should let a installer do the tuning .. usually you tune it to the type of music you play..

For rap, most tune the box around 32-37Hz. I have a 35Hz box in my current set up, and it sound very good IMO. You should not buy a box prefabricated because you should have a box build to your sub's specific specifications. And no, bigger is not always better.. It depends on what your sub works better with.
