That is quite a generous supposition.

No disagreement there. I think it can be helpful to maintain an effort at empathy, in the sense of trying to put oneself in the other's shoes to think about why or how they might have adopted the course of action or line of argument they have. In my view - which of course is just one person's view with no special weight - it can be useful as a "sanity check" or "just exactly how wrong is the other person" check.

In this case, even applying that very generous supposition to Eric Alexander's action here, it doesn't help his case or justify his actions one bit. If this generous supposition were true, it would mean he either (a) thought the ghastly frequency response curve in that image accurately resembled the response of his speaker, (b) thought the raw driver response of the woofer could be used as a dependable reference for its response in his speaker's enclosure and with his speaker's crossover network, and/or (c) thought that this response curve, whatever it represented, did something to support his claims about Amir's measurements and review.

None of those possibilities reflects well upon Alexander's credibility or his claims, to say the least.

Well done by Erin. The results are entirely unsurprising.

This is a fantastic opportunity for @Eric Alexander to reflect on this situation, bring it to a close, and remove any and all pressure from Amir and Erin. Doubling down now will bring nothing but harm to his business and future endeavors. A wise man would let it end here and now.

The sad part is I think he will double, triple, and maybe even quadruple down, and basically destroy his company! The people who will most likely feel the burn the most are his employees, not him!

Absolutely fair review, and as he states it wasn't even negative to start with. All this fuss and for what!

That's the finishing part as far as I'm concerned, the first review actually made me re-evaluate my idea of Tekton, after all this though, not a chance.
Initially they looked better than you thought this kind of driver arrangement could . I thought theese where sh*te before the review . So the OG review actually improved my pov on Tekton " OK they can make this driver arrangement kinda off work interesting !" . I would not consider these for various reasons like the of axis behavior is not what one expects from modern speakers and some other issues i saw in the review...

But after mr tektons response ?? I'll pass on this brand

I’m not on Facebook, but Eric Alexander allows plenty of information to be publicly viewable. I found this post which I think gives an insight into his character.


View attachment 363194

He thinks that he is a maverick “expert“, and likes to arrogantly throw shade at the real experts and scientists. I imagine he mainly lives in a bubble of people not questioning his “expertise”. Two science-based reviews quite close together will have seriously dented that curated facade. His arrogance only allows for one type of response…
I’ve read both threads concerning EA from the beginning and have held off making any comments. But this, this is bat-shit crazy.

Out of curiosity I watched a couple of his older YT videos and I think he's got some neat ideas. I can't substantiate any of his claims especially regarding his patented tweeter array, but the concepts at least seem interesting from a layman.

Excellent new review/response from Erin.

From early on, watching Eric’s posts here and knowing previous history I was feeling somewhat sorry for Eric. There’s something self destructive going on there which is going to lead to his own misery and I hope he can work through it.

Unfortunately these “issues” often affect other people and in this case folks like Amir and Erin got roped in to dealing with it.

Being human…not always easy. Sigh.

Erin's new review, taken together with @amirm 's additions to his original review, conclusively shut the door on this matter, to any honest, literate observer.

1. Amir has recalculated the M-Lore's response based on @Eric Alexander 's precise instructions for the acoustic center point (6.5" off the conventional center), and the results show no significant difference in the far-field response, just as Amir (and several other members) had predicted.

2. Erin has remeasured the Troubadour with the official feet screwed into the holes (the through-holes :facepalm: ), and the impedance bump Erin mentioned is still present, at the identical frequency and magnitude:

Troubador resonance.jpg


3. Erin discovered that if he turns the speaker upside-down, placing the top on a flat, rigid surface, the bump disappears - meaning the bump was almost certainly produced by a cabinet resonance just as Erin stated in his original review. So Eric Alexander was wrong about the impact the feet would have on the impedance bump measurement, and he was wrong about the underlying question of whether the feet were the cause of the impedance bump.

4. Erin's new frequency response measurement of the Troubador using Tekton's recommended acoustical center varies from his original measurement in the key lower treble area in a way that looks pretty much exactly like Amir's recalculation of his M-Lore Klippel data using that same Tekton center point. And the new response in both cases differs by just fractions of a dB in most places. Repeatability of results = conclusive. Also, Erin notes that his original subjective review focused on the Troubador being a little hot in a broad area around 4kHz and a bit attenuated in the higher treble. The new measurements show that the treble is a little less attenuated above 12kHz - but they also show the single largest difference - an almost 2dB increase in the "hot" area between 4-5kHz. So the overall audible effect is either identical with the "correct" acoustic center, or even slightly worse because of the expansion of the higher-amplitude "hot" range around 4-5kHz.

5. Likewise, Erin also compared the frequency response measurement of feet vs no-feet using Tekton's preferred acoustic center point. It shows zero difference from about 180Hz upward, and just as with the previous item, from 180Hz downward the differences are quite small and a mixed bag when it comes to better/worse. With the feet, you get about 0.5-1dB more bass SPL from 40-60Hz. On the other hand, without the feet you get about 0.5-1dB less shelving - aka more bass - across a broader range, about 60-120Hz. So again, no real difference and without the feet arguably gives you slightly more audible bass benefit on balance (especially because Erin's distortion measurements show no significant change in distortion, so that slightly increased bass region without the feet should sound no more or less "clean" than with).

6. The differences are sufficiently inconsequential that Erin has inserted his original subjective portion of his review from the last video, unaltered, in this new review, because none of the changes impacted his listening impressions. I think this also conclusively answers the question of whether or not Eric Alexander's intimidation tactics might have cowed Erin into being gentler or pulling his punches in his evaluation - not one bit. (Not to mention that his original evaluation wasn't even negative!).

7. Finally, Erin has posted screenshots of the emails, in my view clearly demonstrating the inconsistency of @Eric Alexander 's behavior, the unrealistic time demands he tried to make of Erin (asking him to respond literally within minutes), and the untenability of his YouTube video claim that he was not trying to threaten anyone with legal action. Erin also notes that he never wants to hear about Tekton again.

@Eric Alexander , as far as this particular controversy goes, you're done: your claims about the measurements have been disproven - most notably, your claim that Erin created a "false narrative" by attributing the impedance bump to a cabinet resonance and not the absence of the feet, has been totally debunked. So you are the only one who has created a false narrative, defaming Erin's and Amir's measurements and falsely impugning their credibility and integrity as reviewers. From the information available to us in the public, you have also failed to follow through on your statement that you would provide your own measurements, and the disparity between your claims about your tactics and behavior in your YouTube videos and your evident behavior and tactics in the emails Amir and Erin have shared, are on the internet for everyone to see and judge for themselves. You haven't just burned a bridge - you've napalmed it.

I'm just some guy on the internet, but for what it's worth I suggest you take a step back and reflect at some length and depth on your actions here. One thing that seems clear is that you made the oldest "audiophile" error in the book: you made absolute factual assertions about measurable and audible impacts of certain design features (feet) and listening modifications (acoustic center) based on sound acoustic principles, but without any knowledge of how large or small the actual impact of those principles would be. Audiophiles do this all the time - they dismiss measurements and instead take the word of someone they trust because of their engineering knowledge and/or their "ears." It's the classic Argument from Authority rhetorical fallacy. The only difference in this case is that you argued from your own authority.

@MattHooper is wise in the above comment - it's not easy being a human being, and so I am not saying this with relish or joy. But in my view it's quite clear that you have no one but yourself to blame for where this situation has gotten.

yea, the damage is done...his sentiment is probably "take revenge"

I even voted "fine" on the speaker, because the "whole package" (decent efficiency, decent SPL capability, no flaws I would deem too offensive, made in USA, floorstander, 750$/pr) seems fine to me and I can see a target audience for it (and maybe because my expectations are generally on the lower end). What put me off was not the review, but the owners response.

(btw the intro to his 1812 model introduction video on YouTube is... really something......)

In the video did Erin say Eric lost a $3000 dollar order or 3000 orders?

It would be really nice to pin this dumpster fire somewhere/somehow as a warning so that it doesn't get lost to newer buyers considering this brand.

Looks like Tekton yanked their two videos off Youtube or made them private. Hopefully, that's the beginning of their damage control. I sincerely hope Eric takes Ascend up on his offer to learn more about the Klippel NFS. There was no need for any of this. The data is what it is.
