Generally a low EBP value like that is going to have better results in a sealed or 4th order bandpass boxes.

What is a 4th order bandpass boxes and does it mean that the sound will be bad in ported ??

A 4th order bandpass box has a ported section and a sealed section. Heres a pic to illustrate one:

Those woofers were not meant to be in a standard ported box and most likely will not sound good if placed in one.

Not at all, some great woofers sound great in sealed. But for an SPL system you would want to go ported.
