I was delighted to see that BlieSMa is about to release it's new 3" dome midrange in 4, yes, 4 different flavors: paper, silk, Mg-Al, and of course Beryllium. They all use the same motor and with the exception of the beryllium, all cost about the same, which is to say a lot. And it gives a lot: 97dB, flat to 5K and beyond depending on material, and a very smooth FR with good to great distortion numbers.
I'm pretty sure that any of these would make an exquisite centerpiece in a three way. At the same time, I wonder what people think about the "sound" of different materials, not out of band resonances, but the sound that is felt by some to be inherent in the material used. If you read through to the end to the subjective impressions, you will find all manner of adjectives to describe the sound, paper is a liar, silk is oooh so sweet, but too soft, Aluminum too loud when it's time to shut up, and Beryllium which just drills it, yet truth is not always best, when unvarnished. Or words to that effect.
Check out the differences in dispersion--I am not surprised that there are differences, just wasn't expecting silk to be so far off the mark. Waterfalls are interesting as well, Beryllium rings like a BEll at 10K (reflection from enclosure?) and no where else. So by far the best behaved.
Obviously there are differences among these drivers: but do people believe that they all sound alike, assuming no breaks-up, within comfortable limits loudness wise, and well within the frequency range for all the drivers--lets sax 600 to 4.5K?
As for myself, I don't know, I've never heard four flavors of one driver. Nor am I sure which would I'd buy, leaning toward silk...., but the BE is textbook.
Oh if you have trouble with translating the article, Chrome will do it automatically, and google translate should work within other browsers.
