I found some Roxul AFB which is a little easier to work with than fiberglass (itchy) but hard to locate sometimes.<br /><br />Why the pegboard? I would think that would not absorb HF as well as a cloth front. Can you expand on that &quot;frequency spectrum&quot; thought a bit more.<br /><br />Appreciate your help!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8547568058334781866.post-60908081083352593552009-09-14T12:10:38.402-07:002009-09-14T12:10:38.402-07:00@Anonymous Regarding which type of insulation to use, the main factor is density, more dense insulation will generally absorb more sound.<br /><br />If you&#39;re interested in different sonic characteristics, try using other semi-permeable (squishy/fluffy) materials instead of insulation like foam, or clothJim Roberthttp://www.blogger.com/profile/05704161974218670376noreply@blogger.comtag:blogger.com,1999:blog-8547568058334781866.post-4454907655113838102009-09-14T09:01:18.673-07:002009-09-14T09:01:18.673-07:00Jim, what kind of insulation works best?

Oh, and the cancer. I think foam is a safer, more viable option. <br /><br />Otherwise, amazing how-to, Jim.
