How to tame resonance?

[srckkmack]

The best we could do so far is to place the subwoofer on two thicknesses of 5/8 inch rubber pads to help isolate it from the floor.

That is a good point. I have read that isolating the subwoofer from a wooden floor can help with low frequency resonances. Many people have said good things about the Auralex subdude.

Are you sure what your hearing is not that printer or somthing else vibrating with low frequencies. I would play 17hz - 25hz test tone and walk around listening to every little thing in the room while each tone is playing. Im sure you will here objects start to buzz when certain tones are played that you can fix by moving them or putting somthing between them like folded up paper towels or something to absorb the vibrations. I had a hard time trying to tame this beast of buzzing vibrations


Heres what caused it

I have ordered a Auralex Gramma and will post new graphs after it gets here. On a side note it fits perfect under my PB10 according to the dimensions.

I have about 3/4" to spare for the rubber feet on my Auralex subdude.

So now the question is... Does it do the trick?

Yes it does the trick. I feel the difference and my room thanks me. It is somewhat difficult to measure. It is quite obvious if I scroll down on the waterfall results but for the sake of making a typical example, I left it alone for the images. Here are some test I did. My ceiling was buzzing during the test without the subdude in use.

I don't know if it was mentioned, but the first thing I would do is move the sub !!!

It's often a bad idea to put it in the corner.

I realize you don't have much room but try to move sub to center of the one of the walls. I'll bet you'd see a large improvement by swapping "Printer Stands" Try to get it away from the wall as much as you can too.

When getting a new sub or speaker the FIRST step in optimizing it is placement. The LAST step is equalization.
