I'm glad I ran across this post. The NHT Xd was one of the speakers that I was considering auditioning.
In my opinion, transparency is the most important attribute that a speaker can have. I want to feel like
I'm listening to the actual performance, rather than feeling like I'm listening to the stereo. If as John Atkinson states,
the NHT Xd lacks the transparency of a conventional speaker; then I don't see how it belongs in Stereophile's
Class A nor Class B.
I guess this is one speaker that I can safely cross off my list of speakers to audition. Morbius, thanks to you and
John Atkinson; I won't be wasting my time listening to the NHT Xd.
Oh good grief
Barb, if that is your real name, if you're that much of a sheep, you're right, please don't listen to Xd. Xd is not for people who buy based on what people tell them. It's for people who who think for themselves. It's a music lover's speaker, not a speaker lover's speaker. The B&W Dogmatic Lemming Society still has a few spaces for group thinkers such as yourself.
OK, John, you're officially off your rocker. It's one thing to tangle with the regulars on this thread, we give as good as we get. In fact I think that Dr. Greenman has an unhealthy fixation with you.
But Barb J did absolutely nothing to you---nothing. She expressed a sentiment that, frankly, I disagree with too, but it wasn't personal in the least. And in return, you throw crap like this at her?
Get a friggin' life.
And lest you think she's one of us in disguise, that would mean that the perpetrator tried to cover his tracks by posting this post FIVE MONTHS AGO before heading over here. Besides, there's only one person on this thread who has a track record of claiming to be someone he's not.
You owe Ms. Adams an apology. Period.
Well, she owes NHT an apology. Period. Let's start from there and see if we can work our way forward. Or not. (BTW, no she really doesn't owe anybody an apology except maybe herself, but while we're randomly and ridiculously saying who owes who what just because..........)
BTW, people wonder why reviewers piss me off so much. This is *exactly* why. They make these pronouncements or comments such as this and it instantly changes how people think. People say that "c'mon, it's just Stereophile, people will listen for themselves", but this is why I'm sure there are several hundred people who will read that one comment by Atkinson and think "oh, I'm not going to bother listening for myself now" and even dozens more who actually listened, liked and were going to buy a set, but now are thinking "oh, this expert says they're not that transparent even though dozens of other people say they are and I don't trust my own hearing, I'd better not buy them". I'm not pissed off at Barb, she has the right to do whatever she wants, even though I can hardly believe she said that. But Atkinson? Talk about yellow journalism. But things like this do make me feel wonder about the human race. Are we really so intellectually lazy and easily controlled by others that we make $6000+ decisions based on one line in one magazine by one person? Yeah, I guess we are. And that's just so sad. No wonder why Bose is the biggest selling speaker in the world.
Verdict is in...you are one sick dude.
What is it about you that makes you tick?
John..you are a joke or should I say a fraud,
I predicted at the onset of this thread that you (as always) will be responsible for the mod closing it
Whilke I do agree with Michael regarding greg's obsession with you , my comment in the post to which you objected was based upon all of the above posts of yours which to me serve to corroborate your obsessive compulsive personality. It seems that now we not only have to hear from you regarding the virtues of the NHT system but so also the written accolades from countless clients of yours. What is it exactly that you have to prove here as well as on every other forum that repeatedly and predictably degenerates into incessant arguments with people.
You know that in the past I have tried to calm the waves between you and Greg. It is your personality that IMO always causes the volatility in these forums.
Just my $0.02
OK John, i will jump in. YOur obsession with the perception of the NHT is unhealthy.
Sigh. John, the differences between your interaction with her and her lack of interaction with NHT are legion. It's actually quite sad that you don't appreciate that---pitifully, horribly sad that your social graces are so fundamentally flawed.
Like I said, her issue with NHT is between her and NHT. I didn't mean that to suggest that prevents you from claiming she owes them an apology; rather, I meant that to say that we ought to ask them ourselves. So I think it would be a good idea to have an NHT representative come on board and offer his defense of their product in the face of Stereophile's less than perfect review. While he's at it, I hope he will review your horrid response to her and apologize to her himself---as it reflects rather poorly on their company to have one of their dealers rip a potential customer to shreds.
Who knows, maybe Barb will ignore your lunatic ravings and actually be moved to change her mind---which is clearly the objective you should have had instead of deciding to excoriate her.
You certainly appear to be more than adept at making enemies; both here on AVS and at
I'm no salesman, but it does appear to be a rather poor way to sell speakers; which I believe is
your profession. People don't like it when you harangue them that they're "wrong" and you're
"right"; especially when it comes to matters of opinion on which reasonable people may differ.
In addition to Mac at Audio Asylum, you've probably made an enemy of John Atkinson by
publically proclaiming he needs "Q-Tips" on Stereophile's own website:
I see we are now censoring posts that point out the truth. Still, here's the relevant website -http://www.qtips.com
I can provide phone numbers for John to call and speak with people who have traded in T6s for
Xd so he can tell them they're not as transparent. I'd love to hear how that conversation goes.
What is this, opposite day? Seriously!
John Ashman - Audio Designs
The NHT Xd was discussed much here - which resulted in a demo for the BAAS. So there
is / was interest in the subject. I saw on the Stereophile website that Stereophile had placed
the speakers in "Class A - Restricted LF", but that Editor John Atkinson expressed his belief
that they really belonged in Class B.
I also noted that John Atkinson had posted his reasons for believing them to be Class B speakers,
and that John Ashman had expressed his opinion with regard to Atkinson's reasoning.
I found this interesting because, just as OB also noted in post #5 of this thread; that this was
a major reversal for Ashman. Months ago he was forecasting that John Atkinson and
Stereophile would review / test the Xd and that the review would blow everything else off
the map - Wilson MAXX II and X-2 included:
Like I said, the Xd system beats the Maxx and X2 in several critical areas already - phase/time,
tonal accuracy, dispersion. Certainly the ability to adapt to rooms via EQ and time-based room
correction. ...Wanna bet on that one since you already know the Maxx is going to come up short
compared to Xd?
As we now see, that did not happen; and John Ashman no longer holds John Atkinson and
Stereophile in such high regard.
I was not baiting John, nor editorializing; just reporting the state of affairs that I thought might
be of interest to members of this forum; given our previous history discussing the subject.
I didn't mean to "bait" John into reappearing here.
I just meant to say that now that we know Stereophile's rankings - the NHT Xd didn't fare as
well as John had forecast - AND that we see that he's upset about it - enough so that he's been
bad-mouthing John Atkinson and Stereophile. Given the history here, my post wasn't just
about the speakers, it was about John's reactions too - that's part of the story.
Additionally, as I followed some of the discussion on the Stereophile forum - it lead me to the
Audio Asylum. There I saw threads typical of some of those previously seen here. Evidently,
John had been "reviewing" the equipment choices of the "inmates" of the Audio Asylum and
e-mailing them about what crappy choices they made in their choice of audio equipment.
They also complained that he wouldn't stop these e-mailings when asked politely.
In a way, I guess I was saying, "Be glad he's over there and not here" - little did I know.
I apologize for my naivete.
I really couldn't care less about you. I am concerned somewhat about people getting
misinformation because they believe you to be a credible source. I think with this last
thread, you blew away any last remaining shreds of credibility.
At least I know from where my "obsession" comes. I'm very passionate about affordable products that play with the big boys because more people can own and enjoy better sound. The democratization of high-end, rather than a exclusive, elitist social club. If that's an obsession, then I'm pretty content with that.
Yeah, John - we know you're fighting for "truth, justice, and the American way"...OH BROTHER!
The drivers of the Apogee dipoles are ribbons - they are symmetric front to back.
They look, and are; the same from the front as from the back.
Now explain how a symmetric ribbon driver radiates 88% rearward and only
12% to the front?
As anybody should know, a dipole radiates 50% forward and 50% backward,
wilth nulls to the side because the front and back waves are of opposite polarity.
Said "pre-ringing" is also designed cleverly to self-cancel.
ROTFLMAO!!! It "self-cancels" - pray tell how THAT happens!!!
If the "pre-ringing" was designed to "self-cancel" then why was it picked
up by John Atkinson's microphone so as to generate the traces seen in
The graphs don't lie - the graphs that is!!
You just fabricated the "self-cancel" out of whole cloth. Are there any limits to
the degree to which you will dishevel to promote this product that you sell?
The response of a speaker to an impulse should look like the impulse - that is a
flat zero until the impulse, then it should jump up. The raw drivers of the NHT Xd
do that as John Atkinson shows in Fig. 10.
However, when driven by the XdA, the response is that of Fig. 11. The part of the
signal that is responsible for the "pre-ring" has a lesser latency in the digital filter
than the latency of the main impulse in the digital filter. So while the main part
of the impulse is still in the DEQX processor - the "pre-ring" part of the output is
moving the drivers and launching a wave into the air - a wave that is propagating
toward the listener or microphone that the main part of the signal can never
"catch-up" to and cancel.
The "pre-ring" is something that digital filters like the DEQX can do - and high
order, steep slope digital filters are more prone to "pre-ringing" than lower
The "pre-ring" is just part of the cost that NHT [ and its customers ] paid to
simplify NHT's design problems. It's similar to the analogy with the stealth
aircraft. You seem to be arguing the analog that flat-faceted aircraft are the
ultimate in stealth aircraft design. The flat facets of the F-117A were a stopgap
because that's the best that Lockheed could do at the time.
NHT / DEQX should fix the "pre-ring" as they move the technology forward.
You want to enshrine NHT's stopgap technology.
Just as the aircraft industry went on to develop computer software to accurately
model Maxwell's Equation so that stealth technology can be incorporated into
an aircraft with the sleek gentle curves and sophistication of the Northrup-Grumman
B-2 Spirit; the digital filter technology should evolve so that stopgap technologies
are no longer required. It makes the job of the design engineers more difficult -
but it results in a better product for the customer.
Just as the U.S. Air Force now has the B-2, which is a much more capable stealth
platform than the F-117A; I'm sure that future offerings from NHT will greatly surpass
their flawed first attempt. Stay tuned.
I will not be too precise in my my recollection but in the original XD thread, it seems like you thought that Stereophile measurements were going to show how superior the XD are to any other speakers.. So what is happening here?
What I think many here are asking you is to display a certain amount of good faith and .. well .... sportsmanship for the lack of a better word. Anyone considering a pair of speakers north of $5,000 should consider the XD no doubt but it is not in itself the end-of-all speakers. Good it is.. The best ? You know it is not...
John reminds me of a guy, I had in my class in High School who had the ability to get under everybody skin save for the teachers whom he managed to have on his side without being the proverbial teachers's pet. So let it go.. John knows better than anyone when he is wrong and when he is pulling our collective legs...
Dispersion in and of itself; or for its own sake isn't the hallmark of a great
speaker. Besides, I'm talking about how smooth is the response at the listener's
position as a function of frequency due to changes in dispersion - not a graph
that's an average or normalized. Perhaps you think the on-axis response
is ruler flat - but this graph appears to be normalized about the on-axis
response. So any dip with frequency would approx. divide out so long as
both the off-axis and on-axis response dipped.
The dispersion of a dipole is more restictive than a monopole. Yes - that means
it has a small "sweet spot". That's fine with me. I really don't care how the
speaker sounds 45 degrees off-axis because I'm not listening to it there.
Yes - the Xd has wide dispersion - it "sprays" sound all over the room as well as
that venerable old firehose of a speaker - the Bose 901!!
The Xd also "rings like the Liberty Bell". Scratch that - the Liberty Bell is more
muted since it cracked - and it's also "causal" - it doesn't ring until you hit it!!
However, I grow weary of your "fantasies" of the Xd being the most accurate,
