on a box, just block it and clean off all the dust really well.

When spraying an enclosure you want to ensure that the preparation is done right. This can be the deciding factor of the bass response you get from your woofers.

Some things to do:

1.) Ensure wood / board is completely free of dust.

2.) Sand down the edges and corners (I would go with a radius / round over)

3.) Sand down any loose fibers of board

4.) Putty all of the nails / brads that are showing

Spray twice to ensure air tight seal. A company that does this very well is www.atrendusa.com, maybe contact their technical department with questions!

Cheers

posted_image where in the world did you hear that? the outside finish on any enclosure has exactly 0% to do with how the enclosure will perform and the sound you will get from it.

I was thinking the same thing myself. Maybe for the inside? But as for the prep its about spot on.

A spray lined enclosure will offer a few pro's that a standard carpeted enclosure won't..
1.) an air tight seal

huh?? uhhhh yea, I'm gonna highly disagree with you here, why?

because I build all my enclosures air tight from the start, regardless of the outside finish, duh!

and anybody who builds a half decent enclosure will tell you they do the same. dont believe me? ask around on this forum, you'll see what i mean.

I think we all agree, a box should be made air tight from the get go!! This response is directed to the question regarding how a box that is OLD will sound...like I stated...test for airleaks. If air leaks then proceed to spray it...this WILL offer an airtight seal.

Try it on a leaky box and see the difference.

In the case of an air leak it would be much easier and cheaper to just re-silicone the enclosure. BTW if the enclosure is leaking it was not built right the first time! Using spray liner to repair an air leak from a leaky enclosure is like polishing a turd. Sure you can do it, but now its just a polished turd.
