Audio Isolation Pads/Prevent Sound Transfer Between Floors

[JRSC00LUDE]

Looking for insight on mitigating sound transfer from one floor to the other.

I've got a couple tower speakers with 10 inch subs in them. The good things are the floor joists below them are insulated and there is also a layer of sound bar and 5/8 inch drywall on the ceiling underneath. The bad is the wall they are against has all of the heat runs coming through it from below so that wall may transfer sound via those ducts....

Has anyone had good experience with decoupling that makes an effective and noticeable difference? If so, what products or materials?

Realized not what you're after but I used these in my house for a basement suite and never regretted it.
It was very pricey but worth every dollar.

You'd be surprised but the sky is the limit to cater to audiophile nutbars on stuff like this, even to the point of "suspending" things in 3-D space (or so claimed).

Some DIY guys say that hockey pucks will work. A reputable company makes something called Herbie Fat Dots (https://herbiesaudiolab.com/collections/loudspeaker-rack-decoupling-and-isolation/products/herbies-fat-dot). There's E.V.A. Anti-Vibration Pad (https://www.diversitech.com/en-US/category/cat_id/209). Another cost-effective solution is from Sorbothane (https://www.sorbothane.com/anti-vibration-pads.aspx)

Another solution would be to get spikes for your speakers and some scrap granite slabs to place underneath.

The easiest things you can do are 1) Separate your speakers/subs from the floor using something like this or similar: https://www.auralex.com/product/subdude-ii/

What you want to do is decouple your subs/speakers from the floors - spikes don't do this very well and they also can't be used on hardwood or anything else easily damaged obviously.

and 2) Calibrate them (if possible) which will remove resonant frequencies.

None of this is going to make your HT all of a sudden inaudible to the person in the next room but it can make a big difference depending on the current setup.

Awesome, thanks guys!
