Well you are right about the dips and peaks,I wouldn't say they are erratic though.Looking at some of the others like the Soliloquy graghs they(80's) are not to bad and this is a $6400 speaker.All I really can say is they do sound really good.Thats what its about in the end.

Oh, don't get me wrong - I think the speaker can have a close to flat frequency response, as it did in the enjoythemusic graph - I just think the soundstage graph made it appear to be erratic. soundstage did a graph of the Energy C-9 - a speaker that, while having a ruler flat frequency response, some here attest sounds like crap in comparison to the Axioms.

When I initially posted the question I was just looking for the 34-22k +/-3db that is in the M80ti Specifications. I don’t think these charts show that?

Look for where the signal is down three dB, then look at the frequency. Seems like it's flat down to 60 Hz, then is down 3 dB onward until around 34 Hz.

When I first looked at the charts I noticed they started to fall off at about 60hz also.I have mine in a 2.1 set up,so what I did was I got an Outlaw Icbm to do the crossover work.I set the crossover at 60hz going to dual Hsu Vtf-2's.Its all good now.I would think the -3db would be lower with in room response though.

Comments on this graph were posted by Alan Lofft, Axiom's resident expert on 5/28/2004 under the thread Re: NRC data show Energy & Paradigm better than Axiom [re: jbmjr]. Check it out. It won't answer your question, but it'll give it some perspective.
BTW, frequency response numbers +/- 3dB is a range that can describe "from junk to jewels", according to Dr. Floyd Toole.

Thasp... I have heard the Energy C-9's. They were absolutely terrible. Even the guy selling them (Store manager) thought they sucked.
To all... Some of the response curves shown here are poorly done. The 33 millisecond MLSSA graph shown is a total disaster. The time should have been shortened to about 4 Milliseconds. This would have only shown the response from about 150 Hz and up ... but for an in room test, at least it would show the response of the speaker, and not the room...
Sometime this weekend, I will do a proper ETF graph on an M-22, if anyone is interested...

Sounds really good Craig.I was hoping you would respond.I myself don't know much about reading response curves so anything you could teach me would be great.I'm always open to learn.

Good idea, Craig. Yes, that 33ms MLS time window would let in room reflections from up to about 18 feet away, so 4ms would be a better idea. If you'd care to also place the microphone about 5" above and below the tweeter axis, it would be interesting to note the differences in the two measurements.
