remco,

I can't read the language, but - for rockwool products - the following will give you the idea:

Product thickness density 125hz 250hz 500hz 1000hz 2000hz 4000hz
RW5 1.25" (30m100kg/m3 0.10....0.40....0.80....0.90...0.90....0.90
RW3 2" (50mm) 60kg/m3 0.11....0.60....0.96....0.94....0.92....0.82
RW6 2" (50mm) 140kg/m3 0.20....0.75....0.90....0.85...0.90....0.85
RW3 3" (75mm) 60kg/m3 0.34....0.95....1.00....0.82...0.87....0.86
RW5 3" (75mm) 100kg/m3 0.40.... 0.75....0.90...0.80....0.90...0.85


As you can see - the RW3 - 60kg is pretty much the best bang for the buck.

The next logical question would be:

Do you have any novel tips for tricks for the design/building of bass traps?
In other words; Is a sealed air-gap necessary? Are certain dememtions more effective? Any shapes better than others? ETC...Anything you got, lay it on me.

hi every one,....
Rock wool, also referred as mineral wool, is manufactured from a blend of natural rocks by
melting at above 1600°C. It has a variety range of insulation applications from residential to
industrial structures. It is an excellent and cost effective material for thermal, electrical and
acoustic insulation.

In recent years, rock wool as insulation material has gained extensive popularity for its
excellent properties in fire-resistance, thermal insulation efficiency, durability, ease of
installation and sound absorption. High density Rockwool Boards are popular roof
insulation material with high compression resistance.
thanks,...

I use Ph solution for the ph probe but use my D&D refractometer for calib. of the density probe.
I read so much about the accuracy of refractometers but wondering if its worth buying the proper fluid?
