What A Port Buys You
Ported subs play louder in the deepest movie bass and give more output for the money. The tradeoffs are a larger cabinet and bass that can sound a little less tight than sealed. Many subs here let you plug the ports and run sealed.
If your room is small or you mostly listen to music, best sealed subwoofers is the better page.
