Townshend Springs under Speakers

How did that work out?
Ah, I now see edgyhassle is currently using a similar system...

sure; the year was 1976, the speakers were Bose 901’s.

my daughter was 9 months old and crawling all over, so i hung them from the ceiling. hanging 901’s was not unheard of. 901’s had their attributes, and their shortcomings too. but for my lifestyle at that time it was perfect.

in the context of today’s better speakers, the 901’s sucked big time. but for me i was having the time of my life. wish i was "right there" again.

Alarmingly well...  if a touch bass lite

12-18-2016 Springs add another boundary layer and introduce more interfering energy.  The motion artifacts of the springs and resulting inertia when driven by the voice coil of a speaker need to be overcome by the voice coil. If you suspend all speakers from either above or below you have the same retention of interfering energy. And so is your sound.  Tom

And now this..from the Wayback machine..same as it ever was

When energy is applied to soft spongy materials that are used in combinations with springs supporting a loudspeaker, everything supported remains in a state of continuous motion. By doing so, this negates the operational efficiency of a voice coil as the coil itself becomes subjected to this secondary flexing. Ultimately, the voice coil drives the entire speaker assembly and has to overcome the added inertia presented by the motion of the springs and soft materials upon which the cabinet rests. The constant motion and flexing with this type of isolation device manifests inefficiencies within the operational design of the voice coil. Tom. Star Sound Technologies
