How do you tune a box to a specific frequency?

On a sealed box how do you tune the box to a specific frequency. I mostly listen to Rock music, and want a good strong punch out of my box.

Sealed boxes are not tuned, they are sealed. Therefore, you do not need to tune (or should i say cannot tune) the backwaves. peace

Re: How do you tune a box to a specific frequency?

The only thing you want to watch for in the design is to not have a regular shape (i.e. a perfect cube, sphere, pyramid, etc). A golden rectangle on one of the faces is supposed to do fairly well I've heard.

If meant converting a sealed box into a ported box, I don't know how to do it, but just ask, and I'm sure NG or others will answer you. I've been kinda curious myself, but I'm going sealed for now, so I haven't bothered asking.

I think his post is referring to eliminating standing waves by having irregular box shapes (you can have a rectangle, but not a cube, etc). But standing waves aren't a problem until the box size gets up to 6-7cf or larger, so it's not really an issue.

I was wondering what the point that he was trying to make...that was in my mind...but I fealt like saying "WTF" instead

But yeah...standing waves aren't a problem...and If you really care round your corners...lol. peace

Re: How do you tune a box to a specific frequency?

good times and riches an son of a bitches

well different enclosure sizes will give differnce responces because different sizes will give diffenrent enclosure Q.... the bigger the lower the extension but too big and you are basically playing IB.... but nomatter what size shape or what ever sealed is pretty hard to screw up.... it will give a pretty flat responce no matter what.... so dont worry about it :P

well you don't tune it like tuning a ported box but basically the bigger the box the better low end lower power handling and lower SPL. You want to aim for a qtc no lower then .707 in car .8ish is optimal.
