Um - Maybe I should try screen shots! The above was done with white noise from Avia disc.

Trying to attach specs of the mic but can't. Oh well. Anyway, unless I had an EQ to even this all out, I can't see being able to a/b these between the 2 speakers. I think we're going to get the EQ. But does anyone see anything grossly wrong here? Something overtly bad that would be resulting from a bad something or other in a given speaker?

[ben.]

Lordy, that's a lot of typing.

Lots wrong with this picture. The resolution is pretty coarse in the bass. The distance between your first two measurements is an octave and a half. The source and signal path are unstated, as are the measurement tools and methods.

I realize you're not trying to prove anything wrong or right, but I wonder what you're trying to learn here. If you are just establishing a baseline for comparison to the new crossovers that's one thing, but frequency response is only a part of the story anyhow.

If you're measuring in a typical (or really exceptional for that matter) home listening room, a placement differential of inches can render such tests meaningless.

Use your ears. It's what you use to listen to music, and that's why you have the system, right? I respect your inent to gain some understnding here, but flawed methods won't serve that end.

[pauln]

I dumped the data into Excel...

[pauln]

I dumped the data into Excel...

Put in Word but forum disallows, put in HTML, forum disallows...

still trying

[meagain]

Yea, I put it into Excel also but can't post it.

The Microphone was a Studio Projects B1? It's a directional Mic and positioned behind the invisible 'x'. Where we're sitting. But equal to each.

I believe the software is at the top of the numbers in the header.

At this point, I'm more concerned about the differences between the 2 speaks.

I'm trying to get a baseline here. Trying to get the best out of these things.

Yes, I have some issues with the sound.

Done on analog.

I have a 2-speaker at the same time version too.

[pauln]

Let's try PDF... [edit] it worked! Now what do we see? Looks a little Bosey?

m.pdf

[meagain]

Hmm... I assume the vertical column is db? I didn't have any numbers going into the 30's that I can see. So what does that represent then? Oops - I see a couple of 32's.

[ben.]

Look at your room and the mic. The B1 is not a measurement mic, nor adequate for distance micing when low frequency content is a concern. How's the off-axis frequency response of the mic? Is your room and its contents perfectly symmetrical? I could go on, but I don't think I can stop you from wasting your time and energy...

If you want to know the difference between the networks, send them to Crites & he can measure them and tell you which sound better. Probably print you up a nice picture to show you which sounds better too...

The best measurement tools we have are our ears and our brains. We're not putting men on the moon.

[pauln]

Sure you do - Look at the left colomn at lines 141 and 142 - they are both 32...

[meagain]

Uh - Ben.... You're welcome to ignore both this thread & my posts if you wish. Also easy peasy. FWIW - I'm trying to find a way to translate to myself what I hear lacking to my ears. I do not plan to purchase $10k worth of amps or build a new room at this time. I'm first trying to figure out where the problems are technically speaking so I can go from there. Mostly merely compareing the 2 speakers to each other. I think that's a reasonable thing to do. Or maybe I should have ignored the differences and just tossed a new crossover in 1 speaker and compared them. Which I feel would be even more ridiculous.

I plan to get a real EQ with an appropriate mic so perhaps I should delete the thread till I get that?

Pauln - Thanks for doing that chart.

[ben.]

And I was just trying to help. I don't see how conclusions drawn from such flawed methods could possibly help you, and was just trying to point that out. I'll leave you be...

[meagain]

Just responding to some pretty strong jabs. So if my methods are so flawed - what methods should I use to nail down perceived flaws?

I'll just play with the crossovers which may or may not be perceptable, then send them back and live with what I have. Though if I'm going to have speakers that are off and not as perfect as possible, I might as well go with something more petite.

meagain,

you can't really eval new crossovers by installing one. What you

need to do is leave your old ones in and listen to your favorite

demanding tunes several times, then switch them (both) out and run the

same tunes again at the same volume. If you have any critical

listening skills you'll hear some differences right away. Then

just listen normally for a week or so, making sure to play many tunes

your ears have been familiar with. After a week or so play all

your favs again, then switch back to your old crossovers and give a

listen. at that point you should be able to give a reasonable

compare/contrast paragraph or two.

Whatever you do, don't read Max's post in Craigs "this place went nutz" thread. It might hurt your feelings.

I read Max's post and thought it was funny. But at 1:15 am after playing around with a spectrum analyzer - I girl's just gotta SNAP sometimes. []

Meagain,

No offense meant!

Just the last week or so on the forum has been a little......odd......with all the fundamental assumptions and guidelines built up over the years on 2 channel being ripped up en-mass.

All amp conversations to date, for example, take Craig's VRD amp as the most powerful you might need for KHorns and go down from there. Now we start from the VRD's and go up from there - to amps that would be more suited to B&W 800 speakers than good ole horns.

Whatever the suitability of your testing you do seem to have proven that there are differences all over the frequency range. These should be readily audible and we can resume for now that the newer cross-overs represent how the KHorn's should sound in your room.

Whether you ultimately prefer the new sound, is of course, very much up to your ears and those of Hubby.

Somebody post a new thread to advise when she actually listens and reports. I'm w/Ben. I could give a rat's a** for anything that shows on a meter but is inaudible.

I know you said that, thinking you'd be sarcastic, but read it 3 times slowly. That's EXACTLY what you should do if they are not perceptible. If they are perceptible, keep them.

Imperceptible to hearing.... no.

Perceptible to hearing .... yes.

If you perceive them on a meter but not with your ears..... no.

If you do not perceive them on a meter but you do with your ears.... yes

If you perceive them on a meter and with your ears... yes

If you neither perceive them with a meter, nor your ears... no

See any common denominator there? It's all in the ears, baby!

The meters are there to explain why you heard something different. If you don't hear anything different, there's no need to know why - unless, like me, you might want to get a hearing test. Other than that, those meters should have absolutely, positively, hands-down, no influence whatsoever on your decision regarding whether or not to buy those crossovers.

I know you are doing this more out of fun and curiosity than necessity (all the meter mumbo that is). Just don't lose track of your usual, common-sensical self. Would you buy a $4000 amp over an identical-sounding and identical-looking $1000 amp in the exact same condition and with the exact same warranty if the salesman pulled out a meter and showed you what you're not hearing?

Actually I had misunderstood the numbers. I thought one was with the new X-overs and one without. This is merely left Vs right. My apologies.

On the other hand - there is something going on somewhere - could be a very uneven room layout, differences in ouputs from amp (not very likely - but possible I suppose) or the Xovers behaving differently as they age.

Right now your guess is as good as mine.

And it will be all the way through - we went down that road, Max.

She's re-plowing old ground. Those "tests" are indefinitive and only have significance once you've heard something. Then, the tests lead you down a trail as you attempt to discover something. But playing around with meters before you listen is pointless. She's still tweaking around with her old cross-overs and not bothering to hear the new ones.
