Sonic Barrier 3/4" 3-Layer Acoustic Sound Damping Material with PSA 18" x 24"
How does this compare to acousta-stuf? I built a set of karma insignias (ported cabinet, 6.5" woofer, .38 cubic feet volume if memory serves) and used stuffing. I'm building a second pair and want to know which way to go.
How to remove it?
I used this to rebuild speakers that my Father built for our home stereo back in the late 50's. Unfortunately, I used too much by lining all the sides and now it's overdamped. I need to remove some but it's stuck VERY well to the wood. How can I remove it? Heat? Solvent?
This foam isn't really designed to be removed. If you cannot pull it off, I would recommend a heat gun before you try solvents, a solvent might melt the foam itself.

How compressible is this foam? Is it high density?
I am thinking of using this foam to dampen the vibration of a whole house dehumidifier. I know this product is not designed for that but it seems like it may be a good choice for what I am trying to accomplish. I wanted to set the appliance on top of this foam but need to know if this foam is high density before I buy it. i.e. is something heavy just going to compress the foam to the point where it will no longer be serving it's purpose?Thanks for any info!
The foam is compressible, and yes, your appliance would likely flatten it. However, the product is not only foam, but also has an additional layer of fairly dense material which would not compress to any significant degree, and would continue to serve its purpose. For your particular application, you may be best served by a more robust product as the "base" for your appliance.

Using in boxes built into ceiling framing
I'm installing several in ceiling speakers in new work. I plan to build MDF enclosures for my speakers and line them with this material. What are the guidelines for box size and porting? These boxes will extend into unconditioned attic space and be covered with insulation. Boxes will fit between joists and attached to them. Holes for speakers will be cut in bottom, and drywall laid directly on top with matching hole cut through it.Comments?
Ceiling speakers are specifically designed and engineered to perform well mounted directly to the ceiling; no enclosures are required, nor would we have the specifications you'd need to calculate an enclosure size. It would be a moot point, as the ceiling speakers are designed to simply mount into the ceiling. Covering them to prevent the introduction of debris is not a problem, but you honestly needn't worry yourself with calculating an "optimum" box size, porting, damping, or anything along those lines.

Should the volume of this material be removed from the box volume?
With this type of product, it is not necessary to subtract the volume from the internal cabinet volume.
