some suggestions on my sub box?

Question

i just want to know is it better for a sub boks to have a breather hole in it or not? and if it is, why?

Answer 1

porting on the box is a personal preference, as it effects the sound of the speaker in the end. some subs require a ported box and others require a sealed one it should say on the schematic sheet what is required. if nothing is stated about requirements it is up to you. a ported box will make the speaker slightly louder and will create more reverb than a sealed box. a sealed box will have a tighter, punchier sound. it all comes down to personal preference and the type of music you commonly listen to.

Answer 2

kaezoo is exactly right on this question.



To find out if your sub works in a ported enclosure look in your owner's manual. See if the manufacturer recommends ported or sealed for enclosure type. Most subs work well in both so that is when you can decide based on your sound preference.



A ported enclosure will give you more output then a sealed enclosure but at a loss of transient response (the tight, accurate bass). A sealed enclosure has better transient response and usually a smooth frequency response. This menas that sealed is going to be better for sound quality and for many different types of music. The disadvantage is lost output.



If you already have a box don't try to add a port. It is much more complicated then a simple hole or tube. Also, ported enclosures are going to be larger then sealed so you may end up with too small of an internal volume. If you want a ported enclosure get one made specifically for your sub and the type of sound you want.



Good Luck!!!

Some subs work better in a ported box, some are better for a sealed box.



It's not just a "breather hole", though. The port in a ported box is a carefully calculated size, and has to be matched with the sub and with the size of the box. You can't just cut a hole in a sealed box and make it ported. If it's designed correctly, the air in the port will resonate at a specific frequency, adding to the low bass output of the sub/box system. If it's designed wrong, you'll end up with a distorted sound and possibly a damaged sub.



Ported boxes are trickier to design and build than sealed boxes, and less forgiving of calculation errors.
