Why a ported box?
Ahhh....and so the debate continues.
Alot of people will argue the pros and cons of ported vs sealed.
Ported = louder/more air flow/lower frequencies
Sealed = more power/tighter bass
Personal preference/system requirements, really.
Some subs offer the flexibility of either setup, and some are one or the other.
The BL would sound like garbage sealed. Spl oriented subs are not designed to be sealed, and therefore I built a ported box.
