While my attempts at this stage are very crude by comparison (injection channel experimentation is not yet a main priority), I have from time to time listened more with a very crude sort of injection channel plugged into the system.

To answer your question (sorry it took me this long) : Yes I do use metal suspension on all 4 S2s....

Romy,
Ok... I tried it... I backed off the screws securing the rear cover on one of the S2s I use with a pair of 180Hz horns. I backed off each screw a total of two turns, leaving a gap of 1.5mm.
I also did some measuring, and had left a 400Hz ...

Romy,
Forgot to mention... The same people also offer a stepper-motor-actuated version, making it possible to do what you suggested above.
