Cool people use ported. Leave sealed to the ricers.
If someone is building their own box, and need to ask which box is better, ported or sealed, then they have an inablilty to tune a sub box.
Ports are a low budget way to gain a few db and
if done right, can sound very good. Rare to see (or hear) a well tuned system or ported sub box.
The other way is to buy more powerful stuff, or more of everything.
I have a sealed box, actually, 2 of them. So I guess I went "the other way".
