Adding insulation to a sub
 

I'd like to tame some of the boominess (or hollowness) out of a sub. I got some pillow stuffing at Walmart. What do I need to know about adding it inside? Anything I should make sure it doesn't touch? How much should I use? Can I overstuff it? Thanks!!

Bump. No suggestions? Brian?

;) Well :hscratch:

Honestly I do not know if I would open up a piece of equipment just like that.

In my experience there are more problems with the rigidity of the cabinet and materials than with the insulation.

maybe bfrank will have some idea

Here's one link (with pictures) on the famous Sony SA-WM40 polyfill mod, sounds like what you're talking about doing:

Josh - I modded my Sony 12" sub with pillow filling from Wal-Mart, about a year ago, after reading that link posted above... It makes a difference if you have too much "boom" going on, it's tighter now. Took 5 minutes to do, nothing to really worry about if you're careful, just read the link. What kind of sub? Might be different, depending, but they're all just a speaker in a box.
