Townshend Springs under Speakers

Everything matters and you should  know the goal to know if it's right for you.   I play the violin.....I adjust the bridge, the soundpost, the chin rest, the shoulder rest, the brand of strings, the rosin, the bow, and so it goes.   I'm never happy, and it might change with the piece I'm playing, where I'm playing, the temperature/humidity, etc. ..and so it goes.

Stringreen,

I have designed a new end button for violin. Like my endpins for cello they are highly reactive and responsive to both bow and hand. Private message me if you wish to know more.. Tom

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.
