Ohm Walsh Micro Talls: who's actually heard 'em?

There is a huge discrepancy. That is flat response measured and judged one of the best speakers of its time by a leading publication in the industry and yours is way out of the ballpark for reasons unknown. Yours do not look like anything I’ve ever seen measured from any decent pair of speakers working properly. Something is wrong. I doubt it will matter that much but try 1/3 octave on your gear maybe and then apples and apples comparison can at least loosely be made. If not comparable then I do not know what to tell you other than your measures and those from Stereophile  are radically different for reasons unknown.

Mapman being a fanboy is one thing, but questioning and seeing
plenty of frequency charts from 2 different software packages and still think that some thing is wrong (two separate drivers looking identical)  is a little silly. I have been in the audio industry for years
although I'm retired at this point gives me some background to say what you see is correct. Never said I had to make large corrections
but the Walsh driver does what it does and not one bit more....

My engineering experience tells me to believe what you actually measure and not what someone else tells you. Also, many magazine guys, in all fields, are typically writers first and technicians last. And I have first hand experience on that one.
Believe who you will, but in the end it is the result that matters and not the conversation that gets you there.
I love my used 4XOs, but was mightly disappointed in my new walsh 2.2000 upgrades so there is a variance in quality.

Thank you t8kc....

everything I have done it has been on the up and up as I really don't have a dog in the fight.  (just a bit) this is suppose to be for fun not a Paine in the rear end....
I started to deconstruct the spaghetti switch box, and finally removed the switcher  late this afternoon. And I will replace all the nasty cheap stuff  with  

copper or silver (all of them) and I'll replace them with  WyreWorlds  new OFC copper as I do care? I have capabilities of measuring FFT and laser interferometry if necessary. The top plate is now floating on top of the cabinet held down with wing nuts.
The plan is to make a constrained layer part with aluminum, silicon sheets and Finnply, this should be a exciting next few weeks.
I might even construct a 10 inch F clone from some  very cool materials as I was privy to at my last job in material sciences...

1/3 octave is like driving a Beetle, my preference would be a Porsche Gt 3 RS  that allows much much higher resolution...🇸🇪
PS. The McClaren 650 S is even better, lighter and cool as..s#*_!

Stereophile has been doing and publishing these measures for years so I would not discount them totally.

peter you should talk to JS then to figure out what is going on. Or maybe someone else here with expertise in this area could comment.

Obviously your results apply to your speakers only. But there is nothing to indicate they apply to any other pair so you should be cautious in public there.

I personally suspect you have a crossover issue at this point but I am no expert. JS could help you much better.

I am an engineer and have image processing background but not an audio engineer. 1/3 octave as I understand it is essentially a low pass filter that produces a more generalized output. That would be useful to enable a general comparison between data sets filtering details that matter for exact tonality but not for that initial purpose.

In any case you need apples and apples measures to compare at all. 1/3 octave apples apples comparison is only one possible with data and tools available at this point that is apples/apples. It would show general response with enough resolution to determine if two general response curves are similar or not. From what we know so far I would predict they continue to be radically different with yours still showing  large gradual dropoff all else staying the same.

The review mentioned a small tonality variation detected. It was not clear to me if that was detected by ear only or supported by other measures done but not mentioned. John Atkinson surely has/had good ears but I I would still hope the latter.

Also these were original OHM 5s reviewed. I had original Walsh 2s, same gen Walsh drivers and I a/b compared them to my newer series 3 models when I got them and I can attest that there were significant midrange tonal variations and the originals were nowhere close. Stereophile may have been generous with their assessment and not published unflattering info perhaps knowing JS would attempt to address which he did starting in series 2 models shortly after.
