Not sure if this is the correct place to post this ~ but I am looking for a suitable replacement for the baffling in my speaker cabs. I am tired of the old, tattered, grey stuff that hurts my hands! Any suggestions on an easier material to work with would be appreciated. Thanks, John

You can use un-faced wall or ceiling fiberglass insulation. Kustom may have been using a gray color fiberglass & spraying it black so the inside of the cabinet wouldn't show thru the ports. Most of it is pink today. Should do the same job.

Don't use home fiberglass insulation for speaker cabinets. The fibers are not bonded together and will fly around the cabinet and infiltrate the voice coil. Better, Radio Shack has speaker enclosure fiberglass. It is impregnated with a binder which keeps it all together. But, you will have to spray it black as the color is yellow. That is a MUCH better solution.

C4ster, Glad to have you jump in and join the site. We all are nuts here, and I am glad to be among them. I guess I'm never to old to learn a new trick. I have in the past, used regular house insulation for speaker cabinets and never gave a thought to the fibreglass filling the inside of the cabinet. I'm with JC on looking for a substitute material that won't itch when working with it. I think the compressed cardboard egg cartons are the way to go. It should be a material that won't catch fire easily, Ok, ok. so my playing isn't that hot. My hearing is far beyond telling the difference from the original insulation, or a substitute. ET constantly telling me to play loud, oop's I was doing that 30+ years ago, might have somthing to do with it. Don

The "egg-foam" stuff is used in studio environments to cut down on boominess and weird wave patterns bouncing around the room. It is an interesting substitute. My wonderance is if it will cut down too much on the bass frequencies if used in a bass cab..... Experimentation should bring forth the answer on that, and I guess it is a matter of personal taste too. There is another source for the Radio Shack type stuff. MCM Electronics has it. and Crutchfield too Check their web sites out at www.mcmelectronics.com and www.crutchfield.com

Yes, dense poly foam would work as well. The egg crate type also. All the insulation does is cut down on reflected echos in the cabinet. The echos cause boominess and can reduce the sound output in a ported cabinet. The sound type of fiberglass insulation doesn't itch like the home stuff and even that is better than 20 years ago. 3M makes a spray adhesive that works great to fasten insulation of any type to the cabinet interiors. Just spray it on both surfaces, insulation and cabinet interior. Let dry until tacky and place in position. You get ONE chance, so do it right the first time. Now, on the subject of pressed fiber egg crate. Don't use it. Not that it would catch fire by the hot licks eminating from the cab but the fiber is hard and would not absorb the sound waves much. Fiberglass or foam is better!
