DIY speaker isolation base for a wood floor

audiozenology"That someone would compare Lead to Sorbathane, i.e. a soft metal to a visco-elastic polymer makes me really question what message they are trying to communicate"

I do not understand why it is that you "question the message" perhaps you are confused that both are potential isolation materials with differing traits, characteristics, and qualities. It is rather like a truck and a car they are of course completely different in form, function, and use, but both are motorized transportation.


'That there is something you struggle to comprehend, understand, or apply does not mean others are being dishonest or deceptive to you.

I am not confused, but someone reading a post mentioning lead and sorbothane in the same sentence like they are directly related may be. I don’t need to hide behind hand-waving explanations and insults on topics I engage in.

Lead can be a very effective sound absorber. That is simply fact. It is regularly used in this application due to density and hysteretic loss. It’s hysteretic loss is also such that it is difficult to make a resonant structure out of it. Like anything else, it has to be used properly.

Unlike lead, sorbothane behaves both as a spring (isolator) and absorber (dampener). Think of that like a combination of the spring and the shock absorber in a car (or truck).

Placing lead between your speaker and the floor could only provide some level of dampening. At bass frequencies, that would be almost none. Contrast that with sorbothane, which provides isolation by acting as a spring, and dampening.  Properly implemented, not just buying some random things off the web, you can isolate something to <20Hz, and even <10Hz.


Your attempts to try to discredit me, embarrass me, or whatever it is you are trying to accomplish are not going to work as that would require the knowledge to know who is and is not technically "up" on the topic.

Stop it I mean stop it right now. You have been stalking me and I am not going to tolerate you're abuse. I will post hear as ii see fit without you're attacks and interference.

So my original design is sound? No pun intended. To get a tight grip on the woofer? Without the floor trying to affect it? To spike or not to spike? So sorbethane is out and my neoprene and cork sandwich stays? Or a spring sandwich
 with springs underneath too? Just curious does anyone here have a physics degree. I can hear positive results with my stand. I don't want to start a war with oral howitzers pointed at each other. I'm not trying to brush away any ones opinions. I wish everyone could come to a consensus. Lets have a vote. Without the why's please.
1. Sorbethane
2. Springs
3. Mapleshade device
4. Dedicated supports from my video of the RMAF
5. My device
6. Other. Explain?
