I just wanted to jump in and add that those feet/or platforms will not help you with sound traveling to your neighbors.
Basically, all of the sound is transmitted through the air and the vibrations a subwoofer produces are negligible in this case.
It can help reduce the resonances inside your room greatly if you have an old suspended floor as Andrew mentioned.
In Germany where I live, we have concrete floors, so this has no real benefit. The included pucks are very good.
Before the Arendal 1723 2S dual opposed driver design I’ve also had experience with the KEF KF92 (force cancelling) subwoofer. They come with the typical pucks. I could not feel the cabinet shaking under heavy excursion. I experimented with SVS soundpath isolation which are a much more robust feet on hardwood and it made no discernable difference. I then swapped to Isoacoustics Gaia III which is of superior suspended isolating design and again experienced no discernable difference. I kept it on though since I liked the way it looked.
On the other hand I had experience with Klipsch SPL-150, SVS PB-3000, SVS SB-3000, SB-4000, SB16-ULTRA and they all benefited from the SVS soundpath and the GAIA feet even though they did not eliminate all the cabinet resonance. I have concluded it is the back and forth rocking motion caused by a single driver that may benefit from additional isolation the most, especially on hardwood.
A dual opposed driver cancels a lot of the cabinet directional rocking under excursion and the remaining resonance is not meaningfully benefitting from the additional isolation. For this reason I have concluded the stock Arendal pucks are more than sufficient for the purpose. I may see there is something to gain though, if you were to buy a single driver oriented driver.
I believe Lucas and Kevin have it right. Anytime you have pistonic action without counter force, the object it’s attached to is going to have a tendency to move. “For every action there is an equal and opposite reaction”. This is how physics works. I myself have a concrete floor. The sub has isolation feet as well. However, objects in the room will still vibrate when their resonant frequency occurs. This is not always volume dependant in my experience.
