    Amir, take a leaf out of Danny’s book. “Swap the cheesy binding posts for tube connectors. Change the iron core inductors for air core inductors. Replace the electrolytic capacitors with pollycaps. Upgrade the wiring to a higher gauge and line the cabinet with low res”. Then send the parts out to the customer and charge him almost the original cost of the speaker and call it an upgrade. It works for him!

      - both are quite absorbent
      - both lack transparency

    Almost fifteen years ago I built the (only) GR kit for @$100 and made my own cabinets. Back then; D.R. stated he had bought overstocked drivers in bulk from India and incorporated them in this design. I was never impressed by them and preferred my Overnight Sensations and every other kit I ever built. Years later I see GR are still using the same overstocked drivers. I realize everyone is trying to make a living and how they do it is their business. My fix is to ignore anything from D.R. and GR.

      Don't give amateur designers a bad name! Many amateurs design better products than are commercially feasible because of cost restrictions. Danny goes the other way but still rarely significantly improves a product, usually trading a lot of sensitivity for a little improvement in on axis frequency response only. This is often paid for in other areas, like off axis. You really can't beat a Klippel plot to tell most of the story.

    @randallcollura 11 หลายเดือนก่อน +6

    Hi Amir, thanks for another great review. I was very interested as I bought the X-Statik speakers as a kit and built them during the Covid lockdown. They are wonderful speakers, in my opinion, with some of the best imaging and detail I have experienced. That said, I use them with twin subs and use a bass equalization system so I likely don't have the low-end issue you showed here. I didn't opt for any of Danny's extras (tube connectors etc.) either.

    • @AudioScienceReview
      @AudioScienceReview  11 หลายเดือนก่อน +6

      Auto-EQ and proper crossover will definitely fix/mask these issues. Still, it is better to have a proper bass response in case your use changes.

    • @randallcollura
      @randallcollura 11 หลายเดือนก่อน +4

      @@AudioScienceReview Yes, agreed the less EQ that has to be done the better. That said, there seems to be a trend of using computational power to refine and enhance audio and photographic equipment. Most lenses come with correction profiles and looking at images "straight out of the lens" can be disappointing. I used Dirac room correction on these speakers and found that it didn't make that much difference (no bass correction) but I have heard it make a large improvement in other speakers. Perhaps you could do a video that discusses the benefits and pitfalls of this kind of technology? You seem well suited to address something like this. Apologies if you have done this already.

      He just post an obfuscated video where he never acknowledged the problem. But seems like what he has done is pull the response of the mid-woofers lower. That may fill the gap some but the resonant peak will remain. He has no anechoic measurements to show response below 200 Hz so it is all guessing until someone like me tests them again.

    the problem with hifi companies is that many of them come from one „guru“ type hobbyist that turns professional by selling their design and have this trial and error type of mentality. Investing in knowlege and measurement systems that let you understand what you design would require work that most them them could not manage to do. (FEM analysis e.g.). So they keep „designing by ear“ and fool themselves and the world by a ton of marketing.

    Your reviews have helped me make choices, thank you :) Question: have you lived with a real piano, or other acoustic instrument in frequent use? I have many electronic instruments, from various eras, including "state of the art", like the Osmose. (Not rich, just old) None can remotely compare to my real upright piano, in the same room, or to a sax, violin, conga, lute etc. I wonder how this fundamental truth can best be measured? You can't share the richness, like a recording, outside the space. Modern gear worship--I'm guilty, belies the weakness of electronic reproduction, even the most expensive. Not to mention the health benefits, compared to passive listening, of trying to play instruments. Might be an interesting subject for a video, with your technical knowledge.

Every time I go to my lesson the first keystroke startles me in how good it sounds compared to my $6,000 electronic one. Real instruments create such an expansive soundfield that it is difficult to capture and present.

    I guess this question should be on Danny’s channel but he always tells everyone to upgrade to tube connectors because five way binding posts are crap. Yeah, what about the five way Bunning post that the other end is almost always connected to with any normal receiver, and any home theater type amplifier. The only amplifier I have found that does not use five way binding post is certain professional amplifiers so my question is how on earth is a tube connector going into the speaker going to change the sound any when you’re still using a five way Bunning post on the other end the signal to begin with

    Oh no. Not another one. Sigh.
    I thought I would point out that the awful frequency response we see in this speaker is much the opposite or inverse of what is possibly desirable toward the goal of compensating for the dominant room effects. Consider the reflection from the wall behind the speaker for example. At very low frequency, down around where the big peak is seen in this speaker's response, the wavelength is long such that the reflected wave from the wall behind the speaker will be only slightly out of phase with the wave coming directly from the drivers in front. Because the phase offset is slight, this amounts to reinforcement when considered in a comparative manner, i.e., compared to what occurs overall at frequencies above a certain threshold located typically in mid-bass or low midrange. As you move higher in frequency (from, say, 50 Hz), eventually the wavelength is short enough such the reflected wave from the wall behind the speaker will be 180 degree out of phase with the direct wave from the front of the driver. By way of example, suppose the front of the speaker is 18" (a typical value) distant from the wall behind the speaker. If we set the round-trip distance (36") equal to one-half wavelength (for full cancellation), the wavelength will be 72" or 6'. This is the wavelength where the reflected sound from the wall behind the speaker will be fully out of phase with the sound coming directly from the front of the speaker, and where cancellation will be essentially perfect such that a deep, deep "suck-out" will be seen in the frequency response heard by a listener sitting in front of the speaker in a normal listening position. To translate this wavelength to frequency, we divide the wavelength into the speed of sound, expressed in the same units of distance. Doing the math, 1125 feet/s divided by 6 feet is 187.5 Hz. The salient point is that if you were to design a speaker with the intent for it to self-compensate for this room effect, you would want for it to have an high peak at about 190 Hz (200 Hz is close enough). You would want this peak to come on abruptly as you move toward it from higher frequency, and then for it to gradually subside as you move lower in frequency, to where somewhere around 100 Hz (and octave lower) the amplitude smoothly crosses 0 then continues to roll off in a very gradual, smooth manner as you continue moving lower in frequency. Thus, the frequency response of this speaker is almost the exact opposite of what you would want it to be if you want a speaker that will self-correct for this dominant room effect. The much-despised dip in upper bass will be exacerbated, and the sometimes-despised exaggeration of deep bass will be exacerbated (but only at one very particular frequency, due to the high Q of the deep-bass peak in this speaker's response.
    There is little point in trying to understand why there are people who still hold D.R. in high esteem and who think that he has high skill with audio design. Anyone with any real sense will know who D.R. really is, when they take note of the fact that he sells $$$$$ power cables and tells people that the $$$$$ power cables improve sound quality. Anyone with any real sense will know that this is a sham. And on this basis, they will make a correct assessment of who D.R. really is.
    For about two seconds, I pondered the possibility of a large number of people pressuring TH-cam to kick D.R. off of TH-cam. I abandoned that thought after about two seconds, because there are obvious reasons why it wouldn't work. Once reason is that D.R. might have grounds for legal action. I'm not certain of that, but the greater reason is that if TH-cam were to kick him off, there are many others waiting in line to take his place.
    The only reasonable, rational response to D.R. and his ilk is for people like Amir to do exactly what Amir does. I admire Amir for his tirelessness in doing this. People who look at this as some sort of feud and who chastise Amir for what they wrongly perceive as some sort of grudge are simply looking at it the wrong way. What Amir is doing is the only thing that can be done about D.R. and others who are like him. The full audio consumer community at large needs someone like Amir to do exactly this sort of thing. This is the reason I applaud Amir, and why I do not find it difficult to cut him slack when he occasionally makes a small misstep. Which he does not often do.
    Thanks, Amir, for what you do, and for your tirelessness in doing it. Please keep it up.
