Anyone replace the springs of a Nobsound footer?


I purchased two pairs of Nobsound spring footers to place under my REL S/812 subs.  The front of the sub is much heavier than the rear of the sub, so the two Nobsound footers under the front of the sub, with all seven springs installed, are compressed nearly 90%-95% (rather than the 50% that I understand is optimal).  I’d like to purchase some stiffer springs to see if this will work better.  
Have you purchased any other springs that were different in stiffness than the springs that come with the footers?  If so, where did you find them?

in advance, thanks!

If you want to experiment go to an auto parts store and look @ inexpensive Made in China valve springs (s/b under 1$ each with tax).

This said, it would probably be about the same $ to just double up on the stock footers.

Live Vibe brass decoupler sets are better than any springs out there. 

Springs lose their tension. 

The rocker springs I pulled from a 1990 Buick 3.5L V8 were plenty springy. Your springs will be fine.

Agree with @carlsbad2 and @audphile1 - easier to use more Nobsounds in the front.  You might get it done with a single extra Nobsound in the front-center of each speaker, or by using two of them at each front corner.  If too stiff, you can just remove some of the springs from each to achieve the desired level of spring compression.

I experienced the same issue when sizing single springs to place under my 180 lb. speakers/stands.  Not unusual for the front to be heavier since the speaker drivers, with their heavy magnets, are attached to the front baffle.
