Being retired from research NOTHING has the density of slate. The lab countertops are usually slate so your balances and micrscopes don't drift from vibration. The tops are complety dead or vibration free. For my own spaekers (been building them for 40 years) I lined my subs with slate. The bass I get with 10" Focals is fantastic. Spiking on carpeting is a must!
Slate under speakers?
My system - listening area is on a suspended floor loft. Wood floor with carpeting on it. As a trial/experiment I currently have formica covered countertop sink cutouts under each of my Snell Type AIII's. No spikes...just sitting on top of the carpet. The difference was an easily noticable tightening up of the sound...more resolution...so I'm looking for a more permanent solution.
I came across some slate slabs (1 inch x 22 x 34 inches) that would would fit under the speakers nicely. Has anyone used slate in this way? If needed I could spike the platforms into the floor.
