depending on the size of the box, it might not be needed. but i like to overbuild my boxes. it ensures the best quality posable!

Do you mean the foam? No. That enclosure is seled (no tuning per-say). The foam is to help with killing resonation.

I say if your going to do it, threaded steel rods is the way to go.

slim j
12-04-2005, 07:10 PM
In your experiences, do you make the rods go through both sides and have a nit on both side of the box? Or do you use those sleeve-coupler type deals for the rods to screw into. (They kind of have a round base)

Threaded rods are the pwnzorz

Parts Express <dot com>. Sonic barrier is the best stuff I've used yet. Better than the egg crate material by a HUGE margin http://www.partsexpress.com/webpage.cfm?&Webpage_ID=3&DID=7&CAT_ID=48&ObjectGroup_ID=137&SO=2

My sentiments exactly. I believe in bracing, but not like he's doing.
