Axiom Home Page Forums General Discussion Technical Questions Dead woofer on an M80Ti...

Had the day off so it was one of those oh well with the neighbors day and it was my time to crank the 80s and Rotel. At 107 dbs I noticed a crackel coming out of my right speaker and upon further examination I noticed the botton woofer seemed to be a gonzo, nothing but a crackle.

Callled Axiom and another woofer for the 80 is on it's way...hopefully this will cure the problem. I had visions of a bad Rotel but I'm thinking the new driver will solve this issue.

[edit] btw, was listening to Van Halen's 'Fair Warning'....paybacks are a um, uh MFer guys!!

told you it ws a bad one!!

hope you get the woofer replaced, and in working condition in no time.

See, you get new toys and just have to break them !

Sorry to hear you had a problem, your luck is like mine, if a defective product is available, I get it.

I really consider this to be a minor incident...the folks at Axiom are awesome and I have faith that the speaker will be as good as new in no time!

I do think a 'proper' break-in is a must for any product purchased and stuff happens, it's the customer support and addressing these sorts of problems that make one company head and shoulders above another. Axiom, in my estimation is head an shoulders above everybody!

Love the 80s though!

If you turn up your speakers that loud, i would be expecting them to break.
If you turn them up that loud too often, i doubt Axiom will continue replacing drivers for free. I suggest a modicum of caution in deciding just how loud one's speakers can get.
Driving my M60s in stereo from a 100W receiver resulted in clipping beginning around 104dB at about 8 feet.
Those going beyond those relative SPL at greater distances are chancing breaking their speakers. With enough power, the cones will hit their physical excursion points. Without enough power, you chance frying a driver.
Take your pick.

Ian and Alan likely know just how loud at a specified distance their speakers can attain, but i doubt they will tell their customers for fear ppl will try to hit those maximums with the erroneous idea that they should be capable of such feats consistently and in any environment.

Maybe it's your expectations Chess for a pair of 80s to start brekaing apart at 100+ dbs but it's not mine nor is it Axioms after discussing this problem with them in detail.

With that said, the conclusion was a defective driver and nothing else.

You are right in the that these folks do know how far their speakers can go, but you are wrong in that they keep it a secret though....I was told today what these speakers can do and believe me brother, I was'nt even close to tearing them up with my system.

Good day, chess.

80s powered by Rotel.

I had a similar problem with the midrange driver on my 60's. Got a new driver and all is well. But when I opened my speaker up I found the connections at the back of the driver were just loose enough to cause an issue. I crimped the connector just a bit and it fit much tighter and there was no more problem. So now I have a nice spare midrange. Sweet.

You might want to check the connections just in case.

Thanks, I'll give it a look since the driver needs to come out anyway!

Just happened to come across this last night :

TomMystery,

Real80sMan is correct. We quote the M80ti's power handling very conservatively. They will handle up to 1200 watts per channel (clean power, no clipping) without damage. There is no internal fusing of the drivers.

The M80s will mate beautifully with the Bryston 4B amp. That is the amp we used for years at the National Research Council in Ottawa for double-blind listening tests. It is also where listening tests and anechoic measurements on Axiom prototypes are conducted.

Thanks Dennis, this is exactly what I was told today by the folks at Axiom.
