Are the tweeters the same between the 80 and 150? Other than physical size, same voltage and all that?

Hi mrgreg,

No, the VP150 does not use the same crossover. Moreover, each time the tweeter in the M80s has been upgraded or the frequency response tweaked or smoothed out (which occurred with the original M80ti), then the v2 and now the v3, the values of the crossover parts are changed. All the v3 versions of the Axiom lineup use the new tweeter.

It's rare that a crossover has problems, but it can happen. When you contact Axiom, have the serial numbers of your M80s handy so they'll know which crossover is in your M80s.

Regards,
Alan

Any way I could keep the one tweeter in the cabinet and disconnect it as a temporary relief? Would this cause to not be the correct ohm rating? Sorry for the newbie questions.

You can disconnect one tweeter, just don't crank up the volume, but how does that solve the noise issue? Does the noise not come from both tweeters?

No it is only coming from the very top tweeter. I am wondering if it could be the wiring from the bottom tweeter to the top. Whatever is causing the issue it is getting worse.

And you tried swapping the top tweeter with a known good one already and the sound was still there, correct? Did you try swapping out the lower tweeter with a known good one?

Yeah, I have swapped both tweeters out with the tweeters from my vp150.

I watched some movie trailers and Skyfall last night, sounds to me like the crossover isn't preventing the lower frequencies from being passed to the tweeters. I went ahead and disconnected them as it is just too bothersome.

So it looks like it really has to be the crossover.

On a side note, watching Skyfall with the EP500 is just crazy, better than in the theaters!

Does anyone else who has the EP500 or above find it to be too much for most music? I have another sub(DEF Tech) that I usually use when listening to music, I feel like I get a better appreciation for M80s with less over the top bass! Just reserve the EP500 for movies!

Hi megreg,
I'm a very lucky guy with four (4) Axiom EP800 subwoofers in my dedicated Axiom home theatre room. My aray of subwwofers delivers a stellar musical performance. It is true that having four subwoofers makes integration with my main Axiom M80s and dual VP180s a breeze. I assure you that you could be able to get a very satisfactory and highly musical performance from your single Axiom EP500 as well. I started my Axiom adventure with a single Axiom EP500 sub. The key is to take the necessary time and action to maximize integration with your main speakers. Your first and most inportant step is to find its optimal location. Axiom offers a video featuring Alan which will facilitates this operation.
Subwoofer crawl

Then the subwoofer volume level should be done using musical material. Depending on your taste for bass content you might feel the need to increase the volume level for movie material. The issue for the right and appropriate bass level for movies is that there is no reference point. Some listeners will find bass lacking while others find it overwhelming and, at the same time for the remaining ones, it is perfect.
