Question

does a subwoofer box really need a hole in it to breathe? inorder to perform better?

Answer 1

The simplest types of subwoofer boxes are sealed or ported. A sealed box has a calculated volume of air inside it; the air pressure helps keep the subwoofer under control so it can handle more power without exceeding its mechanical limitations. A sealed box should be as airtight as possible.



A ported box isn't just a sealed box with a hole in it. Ported boxes combine a calculated volume of air in the box (usually bigger than a sealed box) with a tube of a set length and diameter that's open to the outside of the box. If it's built correctly the air inside the tube (or "port") resonates at a particular frequency while the subwoofer is playing. This adds to the output of the subwoofer to produce more volume around that frequency range.



So the answer is: No, a subwoofer box does not need a hole in it; and if there is a hole, it's not just to let the subwoofer "breathe". If you have a sealed box of the right size for a subwoofer, it's a bad idea to put a hole in it.

Answer 2

good subwoofer companys will tell you optimized size for a sealed or ported box, ported depends on freq. u want ur sub to play at, etc ported is also louder and boomier. music with tight bass like jazz and rock should have sealed enclosures for most accurate reproduction of sound

Answer 3

Yes,you are moving lots of volume of air,it needs an escape path to sound good.If you buid pressure in the enclosure you gain nothing,you hold back the oscillation of the speaker cone.

Answer 4

More like breath out, the hole lets the bass thump better.

Answer 5

yes and no it depends on the woofer and the type of box you want to built
