After doing some research on this forum, the problem may be one of these: amp rattle, cone rattle or bolt not fasten well. I downloaded some test tones and made an CD to do extense testing. The AVR 's sub gain is set -3dB and sub level at 7 o'clock followed sirquack's advice.
I tried to remove the amp out of the box and placed on the floor and listened. The rattle now sounds louder like motor vibrating with some higher freq. The sound came from the box. Since I am using spike, the sound is similar to that I am moving the box around(it is concrete ground). And I found one loosen spike hanging around. I tried to fasten that spike by hand only and listen again, with the amp placed back.
The rattle seems reduce a lot. I realized that if the ground is not flat there may be vibrating between them.
I am thinking if using rubber feet will be better because if I increased the volume to -20dB on AVR I can still hear some rattle.

When I had a rattle problem, I could actualy take my hand and apply a little preasure to the Amp plate when installed and the noise would change. Another thing is that if air is escaping around the drivers or amp, that can make noises. I also noticed that the negative terminal wire post on the back of the amp was loose on mine, so I think that is where the rattle was coming from.

When I played the RealTraps Test tones, my noise was very bad around 20-25 hz, beyond that I could not hear it...

I would just call Axiom, and explain what is going on and what you've tried to fix the problem. They will help you out...

I had to get a replacement,I had the rattle to and it was the woofer. Play the bass thing on Avia where it goes from 100hz to 23hz. Mine started at 60Hz and went to 23Hz. Axiom is great they will work with you to get it right. Once its right you will be so happy!!!!

Did you say you were using spikes on concrete?

If so... switch to the feet. The spikes are intended for carpet.

Yes. I use spikes on concrete. Isn't using spike can make bass more firm? I don't want to make changes now until I got reply from axiom.
btw, what should low freq(<30hz) bass sound like?
Using test tones, I can hear spiders vibration and little port noise ,and some room resonsates.

If I recall correctly, Alan at Axiom has stated that using spikes, rubber, or nothing makes no difference in the sound. The spikes are intended for carpeting to secure the speaker. What makes a difference is positioning of the sub in the room, and what other furniture/carpeting/wall coverings you have. If you have concrete floors, your sound will definately be different. Heck, maybe the sound is coming from the spikes moving around during heavy activity.

Use the spikes if you have carpet and the feet if you have a smooth floor like hardwood or tile. You want the sub to be stable so that when it is working hard it doesn't walk or move. The more stable it is the higher the output as well.

Thanks all suggestion. I have secured all spikes as hard as possible
to minimize vibration. I set AVR sub gain to 0dB,7 o'clock on sub's back and the output seems more stable now ,and yet powerful.

Billy:
I think the point that others were making is that you shouldn't be using the spikes at all on a concrete floor, and should instead use the rubber feet.

I use spikes on a concrete floor covered with carpet with no problems at all.
