I have a Hsu VTF2MK sub, 10" down firing w/ rear dual ports. According the to the manual, if I want to play loud, dual ports need to be opened. If I want deep bass, one port needs to be plugged up.
Back to the point, I guess that seal sub can achieve lower frequency than vented ports, given the driver size, the amplifier, the box dimension, and all else are the same. However, there are many variables in real life. This is only my 2c thought, and my HT setup is a 5.2.
