SOLVED: Room boom

Lately vibration isolation has become the foremost point of interest in my system. After dealing with everything else, I find tremendous sound differences in using various isolation products under every single piece of equipment in my system. Once you get to a certain level, it is a real thing.

Great to hear!

I had a similar issue and removing the OEM subwoofer footers for aftermarket was transformative.  

Great find.  I've tried Vibrapods, but they made speaker wobbly and they also collapsed over time.  Now I live in one story house on the slab + ceramic tiles - vibrations are gone - bass is fast and even, while music has more clarity.

@baylinor ... what do you use for speakers?

Isoacoustics Gaia I

You can see a clear picture of the setup on the second to last picture of my system.

I found 12 used Symposium Ultra vibration platform 

and have one under all my components .

They are coupled with the steel discs component to the 

platform.  The sound is super clear with great imaging 

and no blurr from airborne or mechanical vibration.

iIf you have a chance to grab some used I will tell you they

are a great upgrade

A couple of other decoupling options for subwoofers and speakers include (at a relatively low price point) platinum silicone hemispheres (link 2" and link 2.5"), and (at a higher price point) Equipment Vibration Protectors (EVPs) by AV RoomService, Ltd. (link).

I have used the larger (2-inch and 2-1/2-inch) platinum silicone hemispheres under my subs, speakers, and steel equipment rack for a couple of years now with good results, and I also use the smaller sizes under components and peripherals such as power supplies and digital switches.  As an elastomeric material, their response is similar to that of a damped spring, assuming they are utilized within the prescribed weight limits.

If you are good at DIY, the relatively expensive EVPs appear to be primarily made from Owens Corning 703 and 705 Rigid Fiberglass Board Acoustic Thermal Insulation (link).  This material can be purchased from a variety of sources and is also sold by Acoustimac (link), a company specializing in acoustic room treatment.  The EVP folks do dress it up nicely and sell it as constrained layer footers with a metal and then either rubber or felt facing but, at a much lower cost, you might conceivably try simply setting your sub on a slab of the material.  I have recently been doing something similar with heavy components using 1-inch thick dense wool felt.

Here (link) is an interesting series of posts about the isolation topic.

Good morning all. I found these from Gregg at Virtual Hi-Fi in Poland I believe is where he's located. His very first retail product offered at a discount to get him started. They are good looking under my Velodynes and make a big difference in my room. I'm on a slab foundation with carpet, padding, an18"x24" ceramic tile and then the subs now on these footers that screw into the OE mount points with the supplied adapters. No muss, no fuss. Working very well for me. Worth a look. Goto: < VIBRON Speaker Isolation Feet (4pcs) – Virtual HiFi https://share.google/KXseQZ31mdFaDcqgk >.

Cool use of 3D printing and a great idea.  I really like that they can be screwed into a speaker, platform, or rack.  The combination of using elastomeric material and the geometry of the shape has the potential to be quite effective.

BTW, you can there is a link option when posting here.  (Vibron Footers)

I found the SVS Sound Path isolation feet to work great under my K-horns and Lascala speakers. Very cost-effective solution for my needs.

I’ve used vibration pads similar to those referenced by the OP and they can be quite effective.  However, one should be warned that sustained contact with finished wood floors will result in marks that are difficult to remove.  I recommend that one apply a thin adhesive felt pad to prevent this.

Great to hear you found something that worked for you.

I had the same issue with my KEF Reference 5’s on my oak, tongue and groove floor. I bought some Isoacoustics Gaia ones and they helped a lot, but I still had some issues.  I went to a company that makes granite countertops and had them cut a couple of pieces to a size that fit under the KEF’s and it solved 99% of the vibrations. 
 

It's interesting.  Going from an old entertainment center to a solid component rack made an obvious audible improvement!.
