Csommovigo,
I may get in trouble for speculating here about Walsh drivers, but oh well you only live once...
I am not expert enough to comment on the waveform issue. I can confirm that I am older (under 50 though) and I did not hear anything at 20000 Khz when I ran a frequency response test record through the Ohm f-5s, even on axis with the tweets. I could hear most everything else down to 20 hz pretty consistently. It could be due to anything though in the signal path, from the cartridge up to my ears or some combination of the above.
I'm pretty sure in my younger college days, I did hear something up to 20000Khz when I ran the same test record through my old simpler, (and much cheaper!!!) system back then which consisted of a nice but unspectacular Philips turntable with Audio Technica Cartridge, Hitachi Class G receiver and Ohm L bookshelf speakers.
I may try tghe test again sometime with the L's, which I still run, or the Dynaudio Contour 1.3 mkIIs and see if I hear anything that way to determine if it is in fact my aging ears or not. The timbre of the Ls and the Dynaudio's are both a bit brighter in general than the Ohm Walsh line speakers and I do believe from my listening that the Dynaudio monitors, at least, are better in terms of pure high frequency resolution than the Ohms.
When I read about the DDD driver technology and the materials used (titanium, etc.) and try to envision what they might sound like, it is not a stretch for me to believe that these may very well technically best the current Ohms in the high end detail area, especially in the omnidirectional aspect.
I recall that the Ohm F Walsh driver also used titanium for the high end, but I believe the specs for the F's did not extend beyond 17000kHz or so either.
The other thing I noticed is that the larger German Physics full range speakers are a two way design, like the current Ohms, but the approach there is to use a separate driver for the low end, not the high. I have no doubt that this is a superior design in terms of omni-directionality, since low frequencies are inherently more omni-directional than highs.
The GP DDD driver must clearly be more omnidirectional at the high frequencies than the Ohm CLS design which uses a conventional tweeter there.
The GP DDD also appears to best the old Ohm F's as well in terms of high end extension. Given technology advancement since the days of the Ohm F, I would expect that the GP DDD would easily best the high end of the old Ohm Fs in most every other aspect as well.
Interesting stuff.....
