what would be the best for the trunk. i heard saaled for SQ, ported for loudness but what does bandpass do what are advantages of it.

please search google first there is tones of information like this already posted.

but generally sealed will give best sq ,ported will be louder and if proberly built will have great sq,i use a bandpass box for my pair of 10's it gives me the sq of sealed and the loudness of ported.but over a limited narrow frequency range.(mine will do 35-90 hz)they are generally harder to build and design.

personally i would stick with ported but it all depends on which sub u are using

just my 2 cents correct me if im wrong

It really does depend on the sub(s) youre using. Im currently planning an aperiodic bi-chamber for two RE8s. It will probably get as loud as the ported box, with SQ relatively close to the sealed box, the only draw backs are it might not be as punchy as a sealed box, and well, its twice the size of a ported box. But the advantage over the regular bandpass is that it should sound good and be flatter across a larger range than the bandpass box.

You can read about them here: http://www.diysubwoofers.org/prt/dual_chamber.htm

Also, JL Audio has a nice comparison on their website comparing sealed, bandpass, ported, and isobarik setups/enclosures. www.jlaudio.com

Hope this helps.

bandpass has been described as 'a one note honking machine'. i believe that description is quite right. it'll make a lot of boom but will completely sound like ****.
your best bet for boom and a bit of accuracy is a semi efficient ported enclosure.

Not so fast. Have you heard enough properly designed bandpass setups to know for sure that they all sound bad? For some reason I don't think so. I used to run bandpass and my wife has one in her car now; neither one sounded anything like a "one-note honking machine". In fact, it sounds better than several sealed setups I've heard.

Believe what you will...

The advantages of a bandpass box is that it's generally more efficient than ported and especially sealed. In other words, it will get louder with less power. It will also exhibit less distortion within the useable frequency range.

The disadvantages are that it's more difficult to build, usually costs more to buy, and sounds worse if it's not built to spec. It also acts to hide the sound of distortion from your sub, making it difficult to tell when you're pushing it too hard. And as mentioned, it plays within a more limited frequency range than the other enclosure types.

It also depends on what sub you have. Some subs are better suited for certain enclosures. Just do some research and try to figure it out what will work best for your needs.

^^ Well put.

That is Myth. A myth that started because any moron can build a sealed box well. A properly built and well tuned ported box will be just as "punchy", "accurate" and suited for SQ as a sealed - if not better in some aspects. The key is good design and application.

Any moron can build a sealed box and it will sound good. It takes a bit more skill to build a good ported, and it takes even more skill to build a good bandpass.

If you are a beginner, I would go for ported and do a bit of research before you build and you will be fine. Just don't build a box, through a random diameter pipe in it with a random length and think it will sound awesome because its ported.
