Townshend Springs under Speakers

from someone of like mind... Me..

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

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

said this many times before.

If you have a time aligned speaker and the cabinet is allowed to move then the cabinet motion will be at 1 or more frequencies greater than the motion of the tweeter. As that happens the speaker will never be in true and proper alignment...

In the 80s Polk Audio had a Time Aligned speaker and demonstrated with a Laser Interferometer that when this speaker was unsecured the tweeter was never in alignment with the woofer. I cannot find the printed ad..

tweak……and so few are time aligned and phase correct…so springs “ work “ for them. The narrow focus of tge tgread should have applied… alas..
