2) The same sub in a ported box requires a larger volume. Partially to make up for the port.

3) A sealed box is heard farther away. Hense competition subs are all sealed for SPL reasons. Sealed box can be projected where a ported box uses the volume and accoustics to produce the low frequency. Open the trunk with a ported box and some bass goes away. Doesn't seem as loud.

4) Ported boxes are more "accurate" than a sealed box. They have higher transient response(look it up). Therefore better for natural bass such as a bass guitar, or drum ie rock music.

5) Ported boxes can produce slighly lower frequency than sealed.

If you want a natural bass that is clean and accurate and not looking to thump out the neighborhood. Go with a properly built ported Box(not store bought generic).

If you want hard hitting, slap yo mamma bass, Go with sealed.

I use WinIS Beta.
Or the directions from the manufacturer.
Use parts express for all that you may need.
