Suspended drivers...Counter-intuitive!
Twest,
Thanks again for your help, it never ceases to amaze me how much I can learn from you guys on this this site!
Ray,
I think your AMT drivers are rather exceptional and if you do ever get them into commercial production I will be delighted to be your beta tester!
The Beyma TPL is a fabulous piece of kit but I believe your drivers will be even better.
Phil, ( Cut ' Paste from sister post)
Glad to see you coming round to the Midg0's idea!
Michael is a very clever guy and his ability to think outside the box ( pun intended!) and challenge established thinking is astonishing.
His paper on the effects of voice coil heating / power compression is a landmark insight and has led me down a path with speaker design that has given me great results.
Cheers
Derek.

There are a direct flight from Stansted to 15 minutes from my doorstep...
Or three...
If we are lucky there may be some acoustic live events to get a real reference too..
Not sure where you are going with this, but...
I new and am willing throw ideas out and don't mind the critical feedback.
I am not sure what you are trying to accomplish. But if you desire to hang a speaker loosely to isolate from vibration, I wonder is active feedback would help keep it at a fixed point.
Idea:
The speaker hanging out there is physically connected to a light but rigid structure that is moved by a speaker voice coil or something that can move fast enough. The motor moving the light but rigid structure is attached to speaker wall. An opposite signal than the music you wish to hear is driven to the attached motor. It can be attenuated, amplified, filtered to the band freq of greatest concern. A fudge factor can be added for delay, acoustic impedance, etc... (always need fudge factor)

Try here for a start. Though, as pointed out numerous places in this thread and the rest of DIYA, the difference between ~2 microns and ~7 microns of magnet reaction motion per millimeter of driver excursion is pretty well negligible. Not that things being non-problems has ever stopped DIYers from trying to solve them.
