Some thoughts on ASR and the reviews

I’ve briefly taken a look at some online reviews for budget Tekton speakers from ASR and Youtube. Both are based on Klippel quasi-anechoic measurements to achieve "in-room" simulations.

As an amateur speaker designer, and lover of graphs and data I have some thoughts. I mostly hope this helps the entire A’gon community get a little more perspective into how a speaker builder would think about the data.

Of course, I’ve only skimmed the data I’ve seen, I’m no expert, and have no eyes or ears on actual Tekton speakers. Please take this as purely an academic exercise based on limited and incomplete knowledge.

1. Speaker pricing.

One ASR review spends an amazing amount of time and effort analyzing the ~$800 US Tekton M-Lore. That price compares very favorably with a full Seas A26 kit from Madisound, around $1,700. I mean, not sure these inexpensive speakers deserve quite the nit-picking done here.

2. Measuring mid-woofers is hard.

The standard practice for analyzing speakers is called "quasi-anechoic." That is, we pretend to do so in a room free of reflections or boundaries. You do this with very close measurements (within 1/2") of the components, blended together. There are a couple of ways this can be incomplete though.

a - Midwoofers measure much worse this way than in a truly anechoic room. The 7" Scanspeak Revelators are good examples of this. The close mic response is deceptively bad but the 1m in-room measurements smooth out a lot of problems. If you took the close-mic measurements (as seen in the spec sheet) as correct you’d make the wrong crossover.

b - Baffle step - As popularized and researched by the late, great Jeff Bagby, the effects of the baffle on the output need to be included in any whole speaker/room simulation, which of course also means the speaker should have this built in when it is not a near-wall speaker. I don’t know enough about the Klippel simulation, but if this is not included you’ll get a bass-lite expereinced compared to real life. The effects of baffle compensation is to have more bass, but an overall lower sensitivity rating.

For both of those reasons, an actual in-room measurement is critical to assessing actual speaker behavior. We may not all have the same room, but this is a great way to see the actual mid-woofer response as well as the effects of any baffle step compensation.

Looking at the quasi anechoic measurements done by ASR and Erin it _seems_ that these speakers are not compensated, which may be OK if close-wall placement is expected.

In either event, you really want to see the actual in-room response, not just the simulated response before passing judgement. If I had to critique based strictly on the measurements and simulations, I’d 100% wonder if a better design wouldn’t be to trade sensitivity for more bass, and the in-room response would tell me that.

3. Crossover point and dispersion

One of the most important choices a speaker designer has is picking the -3 or -6 dB point for the high and low pass filters. A lot of things have to be balanced and traded off, including cost of crossover parts.

Both of the reviews, above, seem to imply a crossover point that is too high for a smooth transition from the woofer to the tweeters. No speaker can avoid rolling off the treble as you go off-axis, but the best at this do so very evenly. This gives the best off-axis performance and offers up great imaging and wide sweet spots. You’d think this was a budget speaker problem, but it is not. Look at reviews for B&W’s D series speakers, and many Focal models as examples of expensive, well received speakers that don’t excel at this.

Speakers which DO typically excel here include Revel and Magico. This is by no means a story that you should buy Revel because B&W sucks, at all. Buy what you like. I’m just pointing out that this limited dispersion problem is not at all unique to Tekton. And in fact many other Tekton speakers don’t suffer this particular set of challenges.

In the case of the M-Lore, the tweeter has really amazingly good dynamic range. If I was the designer I’d definitely want to ask if I could lower the crossover 1 kHz, which would give up a little power handling but improve the off-axis response.  One big reason not to is crossover costs.  I may have to add more parts to flatten the tweeter response well enough to extend it's useful range.  In other words, a higher crossover point may hide tweeter deficiencies.  Again, Tekton is NOT alone if they did this calculus.

I’ve probably made a lot of omissions here, but I hope this helps readers think about speaker performance and costs in a more complete manner. The listening tests always matter more than the measurements, so finding reviewers with trustworthy ears is really more important than taste-makers who let the tools, which may not be properly used, judge the experience.


Amir is full of himself and a total narcissist.


I dont think that it is good politic and proof of understanding to attack any character or person here instead of discussing his rational arguments...


I myself discussed for many days already here with Amir and he never attacked my character. For sure some posters on ASR as in Audiogon can gangstalk someone and many had attacked or mocked many people here or in ASR . But Amir was and is a gentleman...😊

I disagree completely with him about the order of the factors importance : hearing theory and experience must rules gear measurements not the reverse. And anyway physical speakers/room/ears acoustics measurements takes the cake over some small % differences of some cherry picked electrical tool measures applied to one piece of gear design, out of any specific system synergy and out of any specific room acoustic for no specific ears ...



Anyway only rational discussion makes us different from raging apes..😊


myself i think the same as

However, I do find his site and tribe useful for me to figure things out.

Some gear that is praised to the hilt on this site was also not preferred by me. I have learned to understand the sonic preferences of A’gon posters. That give me some context.




I agree with you, however, you should see what he and his henchman do to others who say anything that doesn’t jive with their cultist methods or how they sensor people who question their methods. Amir deserves everything that was said to him.

I know how you feel...

I was served the same medecine by some ASR zealots when i posted unusual experiments propositions with Quartz and Shungite.Then i quitted ASR under sarcasms and not very polite comments about these experiments propositions .. And i decided to stay here 😊 I only read time to time many excellent threads on ASR .... But i dont think Amir will go so low himself attacking people opinion, he is enough confident in himself to act civilized and rational with his own arguments ..

But ganstalking fanatics exist even here ...

We must pick our language carefully then... I dont think Amir is a "narcissist" because his hearing theory is superficial and subordinated to what  he measured in a short set of measures presented as the main element to pick the right gear piece .. ...😊

i apologize if i reacted and gave my opinion on your post but ...

My best to you sincerely ...


He's a YouTuber who uses this site to promote his, just as numerous others have done here before him. 

My youtube channel was started way after I created ASR by user requests.  Like ASR itself, it is not commercial.  Has no monetization, sponsorships or ads of any sort.  In that regard, I am NOT like any other audio youtuber or most youtubers.  Mind you, with nearly 50K subscribers, there is good money to be had but I refuse to go there.  So whether one person views my videos or a million, it doesn't make a difference to me.

They all rely on controversy and drama to whip up enthusiasm and if there's not enough excitement to generate the clicks they'll invent their own conflicts.

A lot of my videos are educational which by definition don't fall in that category.  I actually don't publish many product reviews in youtube but when I do, many are positive and without controversy.  Here is a combination of both where I talk about performance of Genelec 8050B speaker and  how to read and understand speaker measurements:


Videos are recorded live and uploaded with no edits.  No fancy purple lighting.  No clickbait titles, etc.

The only reason to dislike them would be because you don't like it when reliable data, science and engineering speak.  

But yes, there are a number of reviews showing poor performing gear.  Compare that to reviews on audio channels which they don't dislike anything they review.  As long as they get free loaner gear to test and drive traffic to their channel, the product is the best they have heard, punches above its weight, has darkest background, widest and deepest soundstage, sound analog, etc.  In other words, you can get an AI to write the reviews!



Emotionless listeners have the same MO. They’re mostly civilized and rational because they have no emotion. I judge music and sound based on inner emotion. If I want civilized and rational, we’ll have plenty of that when artificial intelligence/unintelligence takes over. Why do we watch movies that have emotion? We watch them to be entertained because if actors didn’t act with emotion, they would be boring, like robots.

You see, we live in this day and age where people think they need to know everything. If I’m watching a magic trick, I don’t want to know how it’s done. I want to be fooled, I want to be entertained. What is sound, what is music without emotion? Singers sing with emotion. That’s what makes them great. What the heck are people listening to these days? Amir needs a chart to tell him what sounds good? He needs it because he doesn’t know himself what sounds good.

Amir hates tube amps because they measure bad, yet countless audiophiles love tubes, myself included. The guy wouldn’t pass a blind test to save his life. He needs a chart to tell him.
