Axiom Home Page Forums General Discussion Technical Questions My poor EP500! Is it dead?

Mine is several years old and still going strong. One of my favorite investments.

I received an email from JC with a request from the engineer.

The boot has two pairs of binding posts and a wire to go to each side of the woofer. The positive polarity of the wire is indicated by the Axiom writing on the jacket of the cable. Connect one side of the woofer to the amp boot and check for sound, then repeat for the other side of the woofer connected to the other set of connections on the amp boot.

I performed these tests and the woofer is barely moving.
I have the woofer out of the enclosure facing the ceiling and when running 15hz to 80hz tests the woofer shakes very weakly.
The strange thing is, when the woofer is bolted into the enclosure it doesn't shake at all during these same tests.
Is it easier for the woofer to move when facing upward versus facing forward?
I also tested another sub cable just in case but the result is the same.

I'm no longer getting any audible response from the sub no matter how deep the bass is. No cracks, no flutter, no nothing...
I'm getting so frustrated with this sub and I almost wish it wasn't under warranty so that I could just replace it.

JC is going to get back to me after discussing my results with the Engineer.

That is to bad Zak, but hang in there Axiom should make it right, like you said it is under warranty.

Yeah, I understand your frustration! But if it's still under warranty, keep your cool, wait and see and eventually things will resolve themselves. It's better than having to ditch $1500 for another sub IMO.

I received an email from Axiom today:

After discussion with Axiom's engineer it was recommended to replace the woofer. I already put an order for a new woofer to be sent to you. Please, keep me posted once you will have replaced it.

I'm crossing my fingers and hoping that the woofer is the problem.
Has the woofer changed from v2 to v3?

Thanks,
Zak

I just hope that is the issue, and not the amp, can be frustrating all this troubleshooting. Ya just want the dang thing to work. I had issues with my V2 amp in my EP600 some time ago and they had to send me a new amp.

You will definitely get a same sound as previously you was getting. The sound level 75db is sufficient for Yamaha speakers.

When one of my EP500s malfunctioned 1-2 years ago. Axiom not only replaced the amp but also installed the original DSP programming on my request in order to keep both subs identical. Keep your faith in Axiom in bringing your sub back to full function, no matter what it takes. They take customer service and satisfaction extremely seriously.

Zak, did the new driver help? I just got my version 2 amp installed in my 600. and i have the same "underwheliming" experience. The 600 use to be a freaking raw beast, now its like a neutered beast...

I am going to call Axiom. I may end up returning my V2 amp and getting my V1 repaired.. I will wait and see...

Zak, did you take any comparison photos of the back of the amp side by side. It seems like the transformer on the V2 amp is MUCH smaller than the V1's?

Hi,
The new version of the amplifier will give you the same level performance as your previous one. It simply needs to be adjusted differently. Dial Axiom's toll free number 866-244-8796 and Brent will assist you at extracting the full potential of your new subwoofer amplifier.
