Crapy sounding bass toms are marvels of neglect, misinformation, copying ignorance.
After this upgrade poor basstom still sounds crapy but not as poor.
It used to have a towel inside siting on top of bottom skin, a practice practiced after copying others.
Today it was bravely decided to remove the towel wash it and use it for its dedicated purpose and insert a linoleum sheet instead.
So thinking of membrane bass absorbers, linoleum must have the nice property of coverting bass vibration to heat hence damping. See BBC membrane absorbers, Gilford.
A slightly less than 12 inch diameter circular piece had been cut with the aid of a metal point compass and scissors for cutting thin metal.
The linoleum circle at the moment is like a heavily bent vinyl record so does not sit "properly" on top of bottom skin. It is like time space bending on fewer dimensions.
The top skin was tuned a that each cake piece gives about the same resonant frequency.
It now still needs a top skin o-ring and the sound is on the less crapy side.
It still sounds like the bathroom door slamming inside but it is a more wide bandwidth sound on both bass and treble side.
Linoleum has not yet been tried spaced but around the cylinder area of the bass tom.
Can such arrangements be used on top of snare drum instead of mouse pads etc? Or inside bass drum?!
