Have a ~30ft carpeted stage in a hundred person non fixed seating venue that’s “less than ideal” but also "good enough" in construction. Drum kit and shield is basically permanent in its placement and size. The stage has a pretty nasty low‑end boom.
As a temporary (temporarily permanent), would laying out wide 1-inch thick garden pavers with a drum rug on top work as a sort of mass‑loaded drum riser? Will the drummers start poisoning my coffee? My immediate intuit is that the extra mass might help tame some of the resonance from the stage surface.
Am I potentially barking up the wrong tree? I know there's no way to answer in absence of trying and seeing , but in general how do stage mass and tennis ball decoupling interplay with each other?
Also, I did a quick hand clap RT60 using my phone and I’m seeing big energy from 30 Hz to 250hz. The room itself also loves to hum at 175 Hz. I'm also no drummer so Im not to saavy with the ins and outs of risers and drumming surfaces
Common instruments on stage are keys, bass, electric and acoustic guitars.
