Springs under turntable

@millercarbon I tried lots of combinations under the phono including naked single springs. I even added brass weights inside the amp. 
I'll try adding them under the suport board as @slaw suggested.
Of course, it's not to suggest I couldn't start re-tuning all the other springs but that's the path to madness!

@noromance   You mean triangulate the springs under the turntable, rather then under each corner?

My point is that putting you sub woofers on spring is not isolating anything from the bass. Springs or no springs the house rattles just the same.

But it does do a decent job of totally blunting transient function and messing up fine definition in the bass. 

Super stiff stands for bookshelf speakers, massive ones, and lock-coupled to a rigid floor..all that happens for a REASON.

Even though Duke (Audiokinesis) and others have posted this repeatedly a lot of people still don’t know. So here’s the scoop: scientific research has demonstrated that human beings cannot hear low bass frequencies AT ALL unless it is a full wavelength.

Got that? Just to be clear, when we are talking about say 40 Hz that is 1/40th of a second. Just so everyone knows, sound travels at about 1 foot per millisecond. One millisecond is one thousandth of a second. 1/40th of a second is 0.025 seconds. Read that one out: twenty-five one-thousandths of a second.

What this means, your 40 Hz bass note travels TWENTY FIVE FEET before it even registers as a sound AT ALL!

In order to believe bass detail has anything to do with stiffness, rigid floor, things that matter in terms of tiny fractions of an inch, when in reality its FEET that matter with bass, you have to ignore all this science.  

There is no fine transient information in subwoofer bass. None at all. Its all volume. Period.

That is the science.

If I’m harsh its because I know you’ve read this all a hundred times, and simply decided for some reason or other to keep pushing your false narrative. You can stop pushing. It ain’t going nowhere. Because its wrong.

MC, I wonder about this too, especially when people talk about the bass response of headphones.  Duke is a great guy. One of the best and most honest people in the audio business.
