Townshend Springs under Speakers

Thanks for the offer Tom, but as you know, a new endpin has to be hand turned for the precise fit, also the attachment gut has to be installed, varying its length and girth, and then experimenting with soundest, bridge, etc.   To do it right would take more time than I want to donate ....but I thank you for the opportunity.

Hello Stringreen,

Thanks for your consideration of the end button. 
I know there would be a considerable hassle with the installation of my device unless a luthier was building a new violin or viola or had to remove the top to repair a crack or bass bar.

I feel there are many advancements for this device derived from my designs for audio coupling as well as my patents on endpins for cello and bass.

No right angles as these are detrimental for best sound transmission.
Gentle radius and curves only.

The top of the button facing the player has an inverted dome which focuses energy and directs that energy towards the player so they can more easily hear themselves and make any adjustments in touch with hand or bow.

The end button has many fine threads that secure the device to the end block, this provides maximum contact of the button to the instrument for best vibrational transmission. 

The many fine threads provide for easy adjustment of the drop angle of the tailgut across where it contacts the recess of the end button. VTA adjustment  provides a similar refinement and benefit when playing vinyl.

The end button is hollow and then filled with reactive materials and then sealed to contain the elements inside. This build design allows me to focus these materials precisely where the tailgut resides in contact with the end button maximizing sound transmission from strings to bridge onto the tailpiece. 

The result of these features make for an instrument that is more stable where all the connections come together, more responsive to hand and bow, more easily heard by the player along with an apparent increase in both tone and volume into the playing space. 

All these methods describe the benefits of direct mechanical coupling accumulated from my continuing audio journey and then reapplied to musical instruments. 

Stringreen if you ever suffer the need to have the topside of your violin removed contact me and I will be happy to send you one of these end buttons. Tom

if the speaker is on solid ground, 3 spikes is preferred.

That is not my experience.  The isolation provided by Isoacoustics Gaia works better on my speakers than spikes on concrete floor with tile finishing.

i have the kef blades which weigh 126lb you think I can get away with the gaia 2?
I dont like the idea of raising the speaker height and the big gaia 1s are enormous 

Nobsound will do 150lbs+ easy. $30. Springs outperform spikes, regardless of floor, period. Gaia outperform all spikes. But Gaia are only about the same as Nobsound, and not at all close to Townshend. Not just me saying that either. Search around, you will find people who have compared. I have compared all kinds of spikes and cones and springs. Nobsound outperforms all but Townshend, and the gap to Townshend is profound. Others have compared Gaia to Townshend, and the improvement is big enough they all feel Townshend well worth the extra. This leaves a huge gap where it is like the old saying, go big or go home. Only in this case, go home = Nobsound, you are still better than any cone or spike ever made.
