Weird cabinet resonance issue!

Hi guys


So I've just set up my new Alphason stand (Ambri ABRD1100-B) & am having an issue with resonance from my Sky+ HD box & my PS3... need some advice!

The stand has a lower cabinet with a door which holds 2 x pieces of kit, and you can also place a 3rd item (PS3 in this case) on the top.

So I've put everything in, and am getting a really annoying low humming sound from the cabinet when the Sky box or PS3 is on, which I'm guessing is the hard drive causing a resonance inside the closed part of the cabinet. I know it's this issue as if I lift either up the noise stops, and if I open the cabinet door the noise stops. The back of the cabinet is closed in except one small-ish hole for the cables.

I am thinking I could make the hole larger in the back to open it up, but I really don't want to start cutting the cabinet as it's brand new. I would prefer to find something that I can put under the PS3/Sky box which will effectively stop the resonance from transmitting from the equipment to the cabinet.

Does anyone have any suggestions, or has cured this issue in the past?


Thanks!

Re: Weird cabinet resonance issue!

I've used AcoustiFeet from QuietPC to isolate PC cases from transmitting hard drive 'rumble' through to the floor/desk that the PC case is standing on. I'm sure these would help as the acoustic problem you're having is exactly what these are desigined to improve. You could try getting the 'very soft' feet (for equipment up to 8kg).

They're available here: AcoustiFeet Vibration-absorbing Low Profile Silicone Feet

I've found their customer service excellent. And no, I don't have any affiliation with them
