Axiom Home Page Forums General Discussion Advice from Axiom Owners Speaker and subwoofer hum

Geez. That must have a been quite a pleasant discussion! That type of aggravation is not worth 50$. Damn these monopoles and the resulting customer service.

For some reason the issue seems to have resolved it self for the most part.

When I loosen the chasis ground screw now the humming pretty much completely stops.

If I get right up to the subwoofer and touch it, I can feel a SLIGHT vibration, and hear a VERY VERY FAINT hum.

If it stays as is I will be fine, if the problem reverts to how it was I will definitely be buying that ground loop isolator from axiom

BTW, you are supposed to remove it completely, not just loosen it.

hmmm, brent from axiom just told me to loosen it abit. I did remove it all the way when I was testing things out earlier... removing it all of the way produced the same results as just unscrewing it a few turns.

I like keeping it in there so I don't lose the screw-unless there is some reason that I should unscrew it all the way...

Good. As long as it comes from Axiom, it's OK. Sometimes ground pins are close to high-voltage elements and it is hard to garentee that there is not a bit of induction still happening.

Well I ordered the ground isolator from axiom last night. I sure hope it solves my problem. I just hope that the hum comming through my sub is not somehow comming from the cable box itself (which is converting the cable signal to a digital signal). If this is the case the ground isolator will do me no good... I think.

On a positive note, I called my cable company and asked to speak with a tech support manager.

I explained the problem, and was told that if this $48 dollar device will fix my problem then they will credit my account for $48 (It took a slight amount of discussion before they came to this conclusion)

so if it works, I will be making a call to the direct number I was provided for my $48 credit!

Please keep us informed on this.

For what it is worth, I had the same problem with my EP500. The hum disappeared when I plugged my gear into surge suppressors.

I got my ground isolator from axiom via fed ex this morning.

The hum is completely gone!

No more unlugging the subwoofer to watch cable!

I did a quick flip through on several HD channels and the picture did not seem to be changed at all.

During breakfast the channel that was on cut out VERY briefly (like a cd skipping) twice. I changed the channel and it hasn't happened again.

Hopefully The ground isolator isn't somehow interfering with my cable feed.

I will call my cable company monday to get my $50 credit!
