I just wanted to know that the difference between a bandpass and a sealed box and how much does porting a box effect it?
thanks

If it is a prefab bandpass box(one that was generically built), then sealed is much much better. Generally speaking, sealed boxes are for more tight, accurate bass. Ported boxes are for SPL, more boomy, loud bass.Originally posted by cockeyed00 I just wanted to know that the difference between a bandpass and a sealed box and how much does porting a box effect it?

If you are new to car audio, I would strongly suggest staying away from bandpass boxes. They are extremely difficult to build and to tune properly. You pretty much stated the benefits of a sealed box, tight and accurate bass notes. A ported box will have more boomy bass notes. Usually choosing between a sealed and ported box is deopendant on the owners personal taste and the sub. Say you have an Alpine Type-R sub, most people would recommend a sealed enclosure for this because it is mainly a SQ(sound quality) sub. However, say my subs, Audiobahn AW1206Q, this is mainly a SPL (sound pressure level) sub, which is strongly recommended for ported enclosures. Hope this helps.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifOriginally posted by cockeyed00 Okay, if sealed boxes are for tight accurate bass and ported are for boomy bass that means that:
sealed = boom
ported = boooooom
it holds a longer note?
Where would you determine whether to use a bandpass or sealed? When would you say, "...okay, for this set up you should use a bandpass..."? What benefits are there when using a bandpass and using a sealed? what is SQ? and SPL?
