Hello all- I have spent 3 months getting my Axiom setup calibrated properly and I feel like I'm pretty much done. I currently have the EP500 and while it is amazing, I have notice a "rattling" noise when it hits the REALLY low frequencies and it sounds like the driver itself is rattling kind of "loosely". Again this is only at the lowest Hz levels. I tried to tame this by using an Auralex Gramma isolation riser under the sub. It helped some, but I'm wondering if I should use the spikes or feet or neither on the bottom of the sub for this. What can I do to get rid of this annoying rattling noise?

Here is some logistical info:

M60, VP150, QS8's all set to small
Bass out set to "sub" crossed at 80hz
Yamaha RX V2400
Sub is located inboard of the right M60 about 3 inches from back wall and 2.5 feet from side wall.

Don't know if any of this matters, but I can't think that this rattling noise is how it's supposed to sound is it? Again, only at the real low frequencies.

As always thanks to all of you for the great help you always provide.
