Axiom Home Page Forums General Discussion Technical Questions I am having an Aud problem

I can see a faulty Eq and signal test burning a driver if done really badly. Then again, sometimes drivers just blow from normal use - they are mechanical after all. I blew a tweeter on my PSBs in ordinary listening.

Have you just recently recieved your system? If so, something might have come loose inside the suspect M80 and is now causing a problem.

P, where a particular speaker causes an amplifier to immediately shut down, that indicates an internal short in that speaker's wiring which wouldn't necessarily include a driver itself being "blown". If you can open up the speaker to see if a speaker lead has come loose that would be helpful. In any case, it wouldn't appear that changes to crossover settings and frequency adjustments, whether done manually or by an automatic system, would have such an effect.

Thanks John,

I will take the speaker apart and inspect the connections.

Shouldn't the tweeter be having the smoke instead of the baby?

Does he have feathers stuck in his teeth?

I have taken the speaker apart (metric Allen wrench needed...Darn Canadians ) and there are no loose or shorted connections. I checked resistance on each individual driver and all readings are the same with 0.1 Ohm with that of its counterpart. Is there anything else I can check? If not, can I just send the innards of the speaker back to Axiom of do I have to send the whole thing?

Axiom will have to tell you what the next step would be...

I could make a sarcastic comment about a 'good' Rotel amp having problems driving M80's, but I'll resist. I know that Wid lives near enough to me that he can probably find me. And I know he's a gun collector.

After helping satkatr with his 3808's network problem, I feel obligated to point out that you should make sure to check all the simple stuff.



Double check all of the cables and wiring that were affected by this swap. If you put a new amp in your system, you would have disconnected at least some of the speaker wires and re-attached them to the amp. Check all of these. Make sure one of them doesn't have a wire strand that's slipped out and is touching the chassis or something, for example.

Double check whatever RCA/XLR cables you're using between your Denon and the Rotel. Try swapping them to see if you can make the 'bad' channel move. Make darn sure that there isn't something wrong with one of your wires before you go ripping into your M80's.

But yes, from the troubleshooting you've already done, it sure does sound like you've somehow got a bad M80. Definitely get Axiom involved with this. From past experiences described around here and since you seem comfortable taking your M80's apart, it's likely that Axiom will just send you whatever replacement parts they feel appropriate. Easier & cheaper for them to send you a new woofer or crossover rather than you having to send all of the innards back to them.

I'd just call them and describe the problem. They'll help.

Edit: Lucky post # 777 for me. Woot.

I just had my holographic sight bore sighted too

It's clearly a speaker problem and not an amp problem. Most certainly call Axiom, not Rotel
