Axiom Home Page Forums General Discussion Stereo Speculating on Axiom’s Olive scores

I think the Olive number is just another input in thinking about a speaker. I’m not quite sure if I see a strong practical use …
think someone is going to need to point it out to me before I see it.

Now …
I do have problems with patents like this one … it really is not adding anything new.
I believe It’s taking know inputs, which I think were developed by others, and combining them. In this case with a linear regeneration.
That seems like an obvious step. Now if he came up with creative ways of refining & normalizing the data or completely new input variables that might have patent potential.
And he may have … I didn’t dig too deep.

As you have mentioned it could be a powerful marketing tool.

In a practical application I think having Dirac or Arc Genesis makes virtually all other metrics moot.

Pick a speaker with high spl, low compression and smooth directivity index. Cough… Axiom!

Set up system.

Measure with Dirac at 17 points.

Set up a measuring Mic with Audiotools.

Tweak response in real time with Dirac and confirm with measuring Mic in room.

You can literally make your system sound like whatever you want. Like B&W voicing? Do it.

Axioms can be made to suit this purpose perfectly.

I love my M5HPs. So much so, I measured their in room response in my 2ch room and tuned my theater mains to match their response. In a sense, I now have an all Axiom system in my theater…. Even though my LCRs are not Axiom (DIY). BTW I did not tune to the Olive curve. I do not prefer it. That curve does not apply to room response. It applies to design response!

This is the curve I tuned to. It does not look like the preference curves Olive has created. Most people would gasp if they saw this without knowing any more data. It looks bad. It came from speakers that measure exceptionally well. M5HPs.

In a real room, this measured curve sounds incredibly dynamic and realistic. So much so I can honestly say “I’m done.” I now use it to tune systems. It is dangerous to rely on single metrics as a standard of comparison. As I said, this in room response curve looks bad! Ignore the tweeter rolloff. Measuring mic/preamp issue out there.

Here it is with octave smoothing. Again, this is how M5HPs measure in a real room. Their close mic response resemble the preferred Olive design curve.

If you tune their in room response at MLP to the Olive curve it sounds extremely dull. Not sure this all makes sense, but I hope it is of value to someone.



Measured design curve:

Actually I was trying to say the opposite. I do not think manufacturers would what to publish this number.

I have to get this … hopefully the next pre-pro … what are you running that has it?

I think it is powerful if you are a company that scores well. Like Harman.

I use a NADT777. The NADT778 is the new model that superscedes it.

Interestingly, the M5 measured room response applied to my theater mains (with axiom M5HPOW surrounds)) playing in dolby surround yielded this averaged energy when listening to music content. Fits the olive curve pretty closely. This is with 11 speakers playing music in dolby surround. I ended up here without even knowing it!

Dont know if it is averaged in the studio mix, the culmination of 11 speakers averaged from angles and distances,, or dolby surround algorithm, but here we are. Maybe false conclusion. Dunno.
