Tekton M-Lore Speaker Review

[DSJR]

Regarding threaded holes for feet or spikes which may well have been a UK thing which started forty odd years ago? -

It was commonplace for makers to fit plinths of sorts to the bottom of the carcasses into which the spikes or feet were screwed - Here's a couple I've just pulled off the internet at random -

It's a cheap and simple way of having adjustable feet. Nothing to complain about.

The issue in this thread is that the manufacturer claims the speaker performance would suffer without the feet installed (which it factually does not as the measurements show). Nowhere does the manufacturer state that feet need to be installed, not on his website nor in the manual (which also makes false claims about the recommended listening axis).

Now when someone measures the speaker without the feet installed he legally threatens the reviewer. On which planet does that make any sense?

not only does this not making any sense, that supersonic blowhole claim is more counter intiutive....

I think something changed with him around this time. In the not too distant past he used to do worthwhile comparisons of products by feature-sets to really help amateurs find value in products. Then it became voodoo gear and weird shit.

I have heard many people talk about hearing differences in gear (including cables). As much as objective measurement is why I'm here, it has also become clear that "gear synergy" is a thing. Just seeing certain measurements of amps and speakers will tell you that two pieces of kit having the same type of issue (say, rising treble) won't help. If you were to swap in something that measures poorly but in the other direction, it could help the overall situation even if objectively it's a turd on its own.

I firmly believe a lot of people are hearing these differences but aren't educated enough to know why; or they are and don't care to admit it for the sake of views and manufacturer relationships.

The truth is that it's best to hear it all (IMO) so I stay subscribed. Also, he drops deal alerts.

I will admit that I have thought I “heard” differences between cables: but I recognize now that either a) my ears/mind was fooling me, or b) far more rarely, cable in question was poorly designed designed for it purpose—for example wildly high capacitance for its use which turned the cable into an unpredictable filter if used with certain equipment. Specifically, I have experienced that effect when using a weird geometry cable from turntable to phono preamp that with certain cartridge loading and preamps rolled off the highs. Pop a bluejeans or Amazon basics rca there instead as no problem. And I was convinced that the 18ft runs of Kimber 4PR speaker wire do something with certain combos of amps and speakers— they do have measurably lower impedance and much higher capacitance per foot than same gauge zip cord so it’s possible I guess.

But thanks to ASR, no more snake oil for me. I prefer science and reason. Even in the exceptional cases were maybe it’s possible that the cable is doing something audible, EQ is better managed by things designed to do it.

To eschew things like tone controls in the name of purity but treat cables as alchemical eq filters, is evidence of audiophile derangement. To entertain or give a platform for it on a YouTube channel promoting itself as seeking no b.s. low cost high quality audio, is I believe a real disservice to its watchers.

I started in audio at a time when "gear synergy" was definitely a thing. I AM SO GLAD THAT IT DOES NOT NEED TO BE AN ISSUE IN THIS DAY AND AGE THAT I CANNOT ADEQUATELY EXPRESS MY JOY!

It was like seeking to avoid potholes in a dark room while you're blindfolded; more failure than success. That's one of the major reasons that I continually harp on the advantage of tests and measurements; they've added light to the quest and removed the blindfold!

I can assure you, audio gear that is provably well-designed is a blessing!

I surmise that way back in the day, there was some technical basis for the premise of “gear synergy” or at least matching in terms of input - output impedance mismatch as a well as input sensitivity and output voltage levels, etc. those days are long gone of course…

Box losses [4 leaking holes] are easy to predict and measure. Furthermore, once we get into the 5-10 watt range the air pressure jets in and out of them at speeds above Mach1 and they get audible. Hard to fathom a top-notch reviewer not discerning audible jet sounds coupled with Nora Jones and Diana Krall!

Are you serious? at >300m/s speed of air at that hole size is likely hazardous to the table/ desk or any living things somehow going pass it (e.g. cats), if that is attainable with a large enough air volume moving to create the issue in FR, I would believe it is dangerous to the user...

funny part to me is that with the original review, with the open holes left as is, the speaker don't really look that bad, but after these kind of "reasoning" bs... it becomes apparent to me that at least those who design the M Lore either cheap out to the max and did't remember to use some metal female socket to seal the holes when the spikes arn't used, or just don't want to complete the speaker for those who don't pay extra for the spikes, or just simply don't understand fully what they are doing.. epic example of self breaking reputation

I believe Eric has repeatedly stated in the forum and in videos that the screw holes reach airspeed Mach 1, leading to significant audible sound impairments.

As you mentioned, turbulence reduces airspeed, and what Eric doesn't mention is that you would need to operate the speaker with SPL >95dB to theoretically achieve such airspeed in the screw holes (without considering turbulence).

Furthermore, the resonance frequency of the screw holes is likely around 25Hz. Therefore, with normal music material, the resonance is almost never excited, and thus, no whistling or similar phenomena can be observed.

Additionally, 25Hz is well below the BR tuning frequency of around 50Hz. Therefore, at SPL >95dB and a 25Hz music signal, there is the risk that the voice coil hits the back plate of the motor (if the woofer cone is not extremely rigidly suspended).

One would need to experiment with sine tones between 15-30Hz to see if any whistling through the screw holes can be detected since normal music signal will not excite the screw hole resonance.

Here is a simulation for my 10'' woofer project. Tuning frequency: 24Hz. I replaced my regular 10cm port with 4 holes 6mm. Unfortunately, my software does not alow to scale up/down this graph but it might be that the CALCULATED speed of air reaches 100% speed of sound.

Here is the simulation for my regular port size (5% speed of sound):

All this happens with the reasonable driver excursion of +/-10mm:

Whoa! 125 pages why still bother with this company? Have you heard even bad publicity is good! Ah ah no seriously Amir should close this thread!

That's a good idea about how he might have reached his erroneous conclusions. Had he thought it through a bit further he would have realized that the pressure necessary to drive the air at that speed through holes of that short a length would have exceeded the mechanical limits of the housing (the speaker would have exploded...). If the holes were much longer you could maybe do it at pressures that wouldn't break the speaker cabinet (and possibly the woofer cones). Which software is that?

Where is Eric and his alternate facts.

He’s back on fb. And tried to act like he’s never paid for a review before.

 

[Darthprater]

Actually, I think I misinterpreted that. He twisted my words a bit. Honestly I really dislike the idea that he’s just gonna keep doing this. But he will never own up to it, and he has customers that just don’t care or choose ignorance. What do you do

I'm here for the full screw-hole interrogation.

He'd love to pay for reviews based on his latest post.

Perfect addition to the thread.

If there are any doubts about giving him money, why not just go for a second hand unit? It'll come up sooner or later (probably sooner). Other options are buying a single speaker, or returning them after the measurements (based on failing to achieve the marketing claims which I'm sure will happen)

There is a set of double impact speakers in Victoria BC which is quite close to Amir. $3000 Cdn which is $2300 US.
