I notice putting in against or covered by thicker fabrics or soft blankets it causes almost like a sort of treble reduction and low pass filter kind and has a slight effect on the volume perceived

Look up plate and spring reverb
Plate: https://www.youtube.com/watch?v=u6eZ_JbmBDw (~1:30 to skip to it, but context and Fran is the engineer behind Frantone guitar pedals)
Spring: https://www.youtube.com/watch?v=8KQRPG71T9s
You’ll find lots of spring reverbs. That is the original analog reverb effect. It is just a driver playing the sound through a spring with a pickup (piezo) on the other side of the spring. I’ve built them into custom guitar amps before.
If you want to play with distortion, use germanium diodes and JFET based amp stages wherever possible.
Just using longer transmission tubes can greatly increase the bass of small drivers.
With my experiments with 3d printed headphones pads, the volume of air inside the pad, along with the sealing properties are the primary factor in bass response. Reducing any free space without blocking the path to your ear canal makes the bass go much lower, assuming they are well sealed.
