My new Youtube channel with audio related content: https://www.youtube.com/@kvalsvolldesign As ususal; no-nonsense, controversial, and technical focus for us nerds. The Subwoofer Calibration video has a part where I explain how to read REW measurements. Enjoy.

Unfortunately, there is no simple way to do this, due to the nature of how sound in a reflective environment works. All the information is already in the measurement (acoustic measurement in-room at listening position), but it is not possible to map all the information into one graph that is...

Did many designs on the minimalist concept. Goal was to have as few amplification stages as possible in the signal path. Reasons behind fall short of any logical and scientific evidence. It is something you make just because it is nice, and because it is difficult. Need to source obscure...

Always difficult to grasp exactly what someone else means, when describing properties of sound. You wrote: "good instruments separation with great detail across the board", which makes sense to me, but, I may have misinterpreted. Others have mentioned multitone distortion, which makes sense. If...

Very good and relevant question. Beyond confirming frequency response is reasonably flat and smooth, there is little information accessible on what to look for in measurements on how they represent the sound from a speaker. Separation is one of those properties, one which is important. When...

The review is what it is, and it was not my intention to criticize the review or the reviewer, rather than point out what many may be missing when looking at a flat graph. The bass issue is something that has become part of the hifi foundation, it is in most if not all reviews, it is not...

I think he should be entitled to do so. "Best" will always be in context, we understand that.

Next issue: Bass: A bass-system, properly integrated and calibrated with DSP, is required to achieve good bass. This is not addressed in the review, it does not mention what sort of bass-system was in use, or how this was set up and calibrated. What was mentioned, though, was a desire to see...

Directivity changes a lot through freq range, going omni down <300hz, and at high freq the pattern is quite a bit more narrow than many other typical hifi speakers with flat mounted domes. Is this good, or is it a fault. Perhaps it is intended by the designers of the speaker. What is true...

My intent is to show that there may not be a best, rather there are compromises that the engineers behind a speaker must make, and eventually those chosen compromises leads to the customer having to make a choice as well. This did not come through, at least to me, in my brief assessment of the...

Then you should read more about what I do and what I am.

It is indeed appropriate to address some aspects of this review, and its discourse. This speaker is presented as better than anything else. But the presented measurements show obvious shortcomings and compromises. So how can this be "best there is", for any and all occasions, for any use case...

Likely there is a resonance around 100hz, which causes the issue with booOOoomy voices. Change the scale on the spectrogram from 1s to 100ms, and you will see it.

The line-source speakers are cylindrical sources, they are, as such, actually larger in size, and it is how this radiation pattern interacts with surfaces in the room, that gives the perception of larger images. As for why the Fountek, assuming line-source monopole front radiating, compared to...

Likely it did. Your description of small high-frequency instruments is something I also have noticed. So that had to be fixed. It was possible to at least improve things considerably, so you get body and some size of cymbals and triangles.
