OK - Looks like it's my turn. Sounds like something inside the EP500 has started to rattle on some scenes (for me the new Planet Earth Blu-ray) and it is not calibrated hot (or it wasn't). Looks like from this thread in order I should try: 1) Tighten back screws 2) Tighten front scres 3) Double check some setting is not running 4) Call Axiom!
Thanks Nathan

Make sure it is not the source. I have some TV shows (Seinfeld is the worse for this) that have some poorly cleaned audio that contains some low noises. You might want to try reconfiguring your system so the M60 gets the bass to see if you can hear it there too or not (I can on my M80s).

OK I tighted all the screws and it make a little (??) difference - On further invistigation it sounds like the rattle is comming from the plastic front port. If I put my hand in there and press down the rattle stops. If no music is playing and I press down I hear a plastic squeaking sound. I removed all eight screws holding the pastic front port it in but it did not seem to want to slide out. Any ideas or is it a "Call Axiom" time? Thanks Nathan

It will not slide out as it is attached in side as well. If your careful and remove the front driver and look inside the box, you will see that the port is a two part design that is glued togethor. There are screws inside as well on the back side. Maybe you need to check those internal screws as well, but be careful not to overtighten them.
How cranked up do you have the volume on the sub and receiver. Many people run their subs to hot and create vibrations and rattles.

I recently bought 2 EP500s. One had a bad rattle from the get go. The other developed a bad rattle after only two days. I removed the driver from one sub and noticed that the voice coil had come unglued from the cone (woofer part). On the other sub this did not seem to be the case but did notice that the voice coil did not operate smoothly when manually moving it in and out which could have been causing the rattle noise. After calling the exceptional Axiom customer service line, they sent out 2 new drivers. All is well so far. Your problem sounds exactly like mine. I'd call Axiom and have them send out a new driver. There must have been a bad batch from China recently.

I don't run the sub hot at all (it is about 40% on the back) and was calibrated with an SPL meter originally. The rattle appears to be more related to a specific frequence (harmonic resonance?) than a particular level.
Looks like I'm calling Axiom Monday to see what they suggest as I'm not that keen to start dismatling it just yet!
Thanks Nathan

All is good - the new cabinet only took two days to arrive in Sydney Australia from Canada - I've swapped the bits over and all is good!
Thanks to Brent for sorting it all out without any fuss!
