I take Soundstages word and measurements over the ninjas any day.

I read a review of the Rotel amp I use and it didn't fair well with speakers that dipped below 4 ohm. I've never had a problem and that would indicate to me Soundstages measurements are correct.

You can read it here.

Wid...what I don't understand is why my m80v2 do not pair well with EMO amp, but are perfect with my neighbor Polk LSi15 with no clipping. This is all new to me. First when I bought my Axiom m80, I thought any amp with real power to drive them will have no problem and only the underpower amp is the cause of the clipping.

GS, welcome. "Believe me", or "I think" can't overcome the solid evidence of the measured curve which Rick showed. This was made not by SoundStage itself, but by the NRC(National Research Council of Canada), one of the world's most highly respected independent audio testing organizations. The M80s can be driven to beyond safe listening levels by your 3808 and similar units.

Yeah, the Ninja has a serious beef with Axiom (particularly because of this forum, I believe)--and he hasn't tested the current M80s.

It's really your choice as to which forum population to believe, but at least we've got the graphs on our side.


Yes. I am on your side too. I own Axiom speakers, and this week I really experienced the clipping issue with m80. I read here and EMO forum many stated the 80s are difficult to drive speakers. So I was being stubborn, I tried with EMO amp and now experience the distortion/clipping problem with my speaker. Also, earlier this week I spoke with Axiom tech support...they also said 80s do dipps into below 3 ohms in some frequency. Well, I have to find the amp that advertised in the stable 2 ohm not 4 ohm. I learn my lesson here.

It's fairly simple. The Polks are easier to drive. The M80s draw more current from an amp than the typical 8 ohm speaker making it hard for the the amp not to run into over load.

If it was a well engineered amp it should not be having problems. Look at your Denon, it will drive the M80s fine.

What Axiom tech told you that?

JohnK-Thanks. I do believe the reviews last year that got me hook with Axiom speakers and pulled the trigger. Also, I have in my family are Klipsch RF5 and the sound increabible with EMO Amp. Here listen to these

Wow! After reading Alan's thread I do feel safe. Wid-I discovered the clipping problem happen during music play in Direct and PureDirect mode from Denon DSP. 2 Stereo, 7 ch stereo, and Dolby Digital OK. Could it be the pair problem DENON and EMO amp.
