Vibration Control on Speakers Devialets and Clocks - hardcore - 03-Jun-2025
Recently did some tweaks related to vibration control and wanted to share them:
1. My speakers have spiked feet with adjustable heights. I raised the speakers to the maximum height. They were at the lowest height before. That definitely made a positive difference. Bass tightened up and soundstage became more even.
2. I am using an external DDC (Singxer SU-6) which basically acts as a clock to my Devialets. I put some books on top of it, and wow it improved the soundstage and highs. I guess digital clocks are very sensitive to vibrations. If you have an external clock or DAC, might be worth trying some dampening if you haven't.
3. This next tweak is going to sound weird. I placed a few Ikea HEAT cork mats on top of the Devialet Pros, covering the open window in the middle. I have the 250 Pro / 1000 Pro units with the bigger window on top. Shockingly it changed the sound. It smoothened the highs a bit. Easy to test, just remove the mats and it sounds a bit brighter and more open. Put the mats on and it sounds smoother. The window on the 250 Pro is directly above the "ADH" part of the amplifier. I prefer the more open sound without the cork mat, but the tweak could be useful if your system sounds too harsh.
Now it's making me consider more vibration dampening tweaks.

1. speakers always have an optimal height under a particular listening environment. The factory settings only give you a rough starting point, adjusting the height to optimum can benefit all aspects of the sound, this applies to all speakers, be it bookshelf or tower. Bigger floor standers however is less sensitive to height as it is already that big.
2. putting something on top of any equipment always have some effects, some positive some negative. In general terms, imaging and mids become more stable when damped with something on top of an equipment. Also in general, there may be less airy treble if something is on top of equipment. Different materials also have different damping effect and produces different sound. Usually, I prefer this damping trick only on a few equipment, otherwise one may have changed the tone of the whole system over-dampening all equipment.

@ray1234 (2) is my finding too, i tried placing the cork mats on top of the speaker which also changes the highs and air around the speaker. it probably reduces the reflections from the cabinet. putting padding under the speaker reduces reflections from the floor but also takes some liveliness out of the sound.

Placing some cork mats on top of the window of the 250 Pro / 1000 Pro makes the highs and bass sound cleaner. Got these Ikea HEAT square-shaped cork mats which look less weird than the round shaped ones.

worth trying, I am going to try that on my Expert 400.

I found that if I completely cover the window with a Weetabix, the highs are light and crisp and the lows are deep and crunchy.

lol extra crunchy! we need more pics of things on top of Devialets
the 220/200 doesn't have that big see-through window on top of the ADH like the 250 does though

Nothing on top ... BUT everything under the 220-Pro x Two [440-Pro CI ]

Whoa thats a lot of support!
Wouldn't hurt to try the cork (carefully). I'm surprised it makes quite a difference on the 250 Chassis, maybe because of the big plastic window. My amps are very close to the speakers and I can feel the vibrations on the cork mat.

I believe this will make the sound even sweeter.
