I like this draft... it keeps things open, and very interesting.

 

change the height limit! 21 inches is totally not enough.

 

Chris - what are the heights of your NW boxes you've built over the year? [img]smile.gif[/img]

 

I'm not arguing... I'm just wondering how you need more if most subs are 18" at the most. (I obviously don't compete in that class, so I'm asking for my own info)


That gives you a bit of room on either side to mount.

What would be an acceptable height?

 

yah how tall are no wall boxes?

 

25" is usually the max you can go for no-wall.
My box is 19" tall

 

Lee yhou only use 15" subs wait till you start using 18" subs there is no way you can get a decent box with only 21".

And this is "pro" dont make us use crx boxes that are pushed up to the B pillar.

 

so how tall

 

25"
