Townshend Springs under Speakers

The logic of springs is an easy one to wrap my head around.

Im building some prototype speakers and getting close to sealing them up. Once I close them up and weigh the complete unit (and find the center of gravity for them) I’ll be sourcing the “correct” springs for them and integrating those directly to the speakers bases.

Nominal cost for something that benefits the end user immensely!

I love my Townsend Bars, wouldn't trade them in for anything else. Couldn't tell you how they work, they just do. My 125 lb speakers float in the air, the sway when touched. Everything comes into equilibrium sound-wise for me. 

Well a great speaker may not have such noble beginnings as some of the above. Here we go. Three guys setting around talking one night.
One a speaker manufacture
One an Amp designer
One a master cabinet maker

The amp designer, who doesn't care for speaker design at all, sketches a speaker design on a napkin that he know will work VERY well, BUT has never seen anyone tackle the wide baffle issues with any success.
That was  James Bongiorno. He hands the sketch to Brian Cheney of VMPS. It's a new design for neo 8 planars (Monsoon), Strathearns, BG ribbons, any and every type of narrow planar or ribbon design. Dorn Dibble who is there sharing the single malt is asked if he could do it he says yes I need some tools..

The Elixir was born, HDF front baffle coupled to a MDF bass chamber, and only 16 pairs ever produced, It's an amazing story of 3 drunk fellow designing a speaker one night on a drink napkin.
Pimp Daddy, Mr. Bass and "The Dibbs". 

BTW all were pretty decent jazz musicians at the time before their passing..

I liked him.... Didn't talk much. I watched everything he did.. Man he was fast..

BOOIIIIIINGG!
This must be the most repeated topic here.  No need to keep repeating, the answer is simple:

If your floor is insufficiently rigid then make it rigid or change rooms, or houses.
If your floor goes boiing, adding more boiing with springs will just make matters worse = boiing boiing.
