Title: Recommended spikes or isolation feet for enclosed servo sub?
Post by: coot1957 on 4 Apr 2021, 02:25 pm
Hi,
I am looking for recommendations for isolating the Servo Sub 2's I am building.
Thank you,
Mark

Good morning! I recently put on SVS’ SoundPath Isolation feet on my sealed F15HP. The difference was astounding. I bought them with the suspicion I would need further isolation or would need to upgrade to something more expensive, but I haven’t looked back. They’re basically little inner tubes.

SVS SoundPath Subwoofer Isolation System, 4-Pack https://www.amazon.com/dp/B00NCSQ5GK/ref=cm_sw_r_cp_api_glt_fabc_5CCPRJKAT3XBTB55XJ93?_encoding=UTF8&psc=1

There’s plenty of more expensive options out there that may work better, but this most likely will be all you need.
Hope that helps!  :thumb:

If you want real isolation you should look at Dannys sand box design. I did a variation using lead shoot instead of sand and it is completely dead. I can lay my cheek on the cabinet at hi vol and lots of base and not feel a thing.

As others have mentioned, there are a lot of options out there, so more information will likely get you a response more relevant to your situation:

I have low-pile carpet over OSB sub-floor on top of engineered I-joist suspended wood structure.  I splurged and ordered Townshend Audio Podiums from the UK to put under my mains stack (large 2 way monitors on top of subwoofers having a matching footprint) and was amazed at the difference over the Herbie's gliders that I'd had previously.  (I still use and like Herbie's products elsewhere, however, including between the mains and the subs.)  The Podiums have flat feet, however, so I put a large tile under the Podium footers, on top of the carpet, to remove the variability in their footing.  (I would be tempted to do something similar for any non-spiked solution if placing the subs on carpet / rug.)  These platforms can accommodate an uneven weight distribution, which is helpful in my case, though more due to the front-heavy nature of my mains than the subs under them, as the subs are a dual-opposed design.

I couldn't allocate the funds to put Townshend products under my 4 other subs, however, and went with Isoacoustics Gaia footers and their separately available spike platforms to pierce through the carpet to the OSB sub-floor - another definite improvement.  (I got mine on sale at an audio show.)  Note that both families of products, and quite a few others, offer multiple versions tuned to a specific weight range.

Good luck with your project!

Thank you for the responses. I thought about the sandbox design, but the final weight kind of scared me. I decided to try the SVS SoundPath Subwoofer Isolation System as a start and if needed I can work from there.
Thank you again,
Mark
