No Rez dampening question with LSi15

[chamont]

I picked up some No Rez the other day from GR Research (http://www.gr-research.com/index.asp?PageAction=VIEWPROD&ProdID=103). The stuff is similar to Blackhole 5 (http://www.soniccraft.com/products/damping/blackhole5.htm).

My question is about fill.

After I line my cabinet with the stuff, do I put the fill back in? Should I put less fill back in? Or, maybe a different type of fill?

I've heard good things about No Rez/BH5, but I haven't found anything about what to do about the fill. Maybe I haven't looked hard enough yet.

Ideas?

What is the original damping material,fiberglass,poly?it's thickness?Did it line the cabinet walls or fill the central cavity?

The original fill is 2"+ thick sheets of poly.

The original fill is 2"+ thick sheets of poly.Did the poly fill the cavity or just line walls on top of the 2" material ?I would be concerned about overdamping the bass compartment and reducing the efficiency of the power port by adding too much of the original material back in.
For the bass compartment aleast you could try it with just the Back Hole and see how sounds.If the bass is boomy then reinstall some of the original material.

It filled a majority of the lower cabinet.

It filled a majority of the lower cabinet.If thats the case then I would start with the black hole and just the poly and reinstall it as it was originally.

The No Rez looks very similar to Sonic Barrier from Parts Express. On my RTA11TL's I used a Dynamat like material on all sides, back, top and bottom. Then I lined the back and sides just behind the MW's with the Sonic Barrier and used the original Daycron above each MW like it was originally. I did not put any absorption material behind the PR's. I am very pleased with the results.
