ya, i know what the question was BUT...he did not identify what he was talking about... a ported box is a bandpass box...a "bandpass" box (with the plexi) actually is a dual bandpass box but is just commonly refered to as bandpass.....Originally posted by scott4251 thats not even what my question was moron. It was between bandpass boxes and SEALED BOXES. wether u can really tell the difference in sound in a trunk.
