You have to credit it with consistently terrible measurements no matter where you start: cabinet vibration, frequency response, step response and waterfall, all vying for the worst I've seen on Stereophile. Efficient though.
The full range crowd don't seem to care about the FR. Only occasionally do I see someone commenting on the ear-piercing shrieks at some frequencies.8000€ pair price passive full range loudspeaker with following measurements:

A quick Google search confirmed that there were still users/fans of these loudspeakers as recently as 2020...I nominate the Escalante Design Fremont. Now long out of production, MSRP was $19K/pair in 2008:
These terrible measurements did not prevent this rapturous subjective review:
You pay for convenience. Notching out the 4kHz saves the owner the trouble of notching it themselves.A quick Google search confirmed that there were still users/fans of these loudspeakers as recently as 2020...

many thanks, I was actually looking at those Nenuphars.8000€ pair price passive full range loudspeaker with following measurements:

I'll note those graphs are 1/4 octave resolution. But yes, with enough EQ you can probably tame them.many thanks, I was actually looking at those Nenuphars.
According to the manufacturer, the (latest) drivers actually measure quite well (for a full range). Looks like they did not think much about the cabinets.
With proper enclosures, the 10kHz area can be easily tamed with EQ/DSP and distortion looks reasonable too. But still, such measurements and prices...
yeah I was looking at that, the manufacturer measurements are not exactly same. Vertical scale is also very different, hard to compare the graphs.I'll note those graphs are 1/4 octave resolution. But yes, with enough EQ you can probably tame them.
It seems excessive.yeah I was looking at that, the manufacturer measurements are not exactly same. Vertical scale is also very different, hard to compare the graphs.
For €1000 I would try a pair, but they want €7000 for the only ones which measures ok-ish...
you are very niceIt seems excessive.
Marketing people say a lot of things. Sometimes they aren't entirely truthfulyou are very nice
They go with the story of years of research and low count sales. The website looks ok, provides tech data and some measurements and I can ~understand that story too.
But wtf did they 'research for many years' when those drivers/enclosures have sudden 10dB FR spikes and a 20+dB swing between lowest & highest points ?! Looks like I should forget about those drivers too. Sooo hard to find a reasonable single driver...
And also measured in listening room, not anechoic/gated.I'll note those graphs are 1/4 octave resolution. But yes, with enough EQ you can probably tame them.
Most coaxials have a dip in the highs due to diffraction which is increased exactly on-axis due to the symmetry and mostly disappears though off-axis, current Genelec and KEF being rare exceptions.Why do they hate 6.5kHz?
My 511s do something suimilar, probably for the same reason, although it's only a few dB at 2kHz.Most coaxials have a dip in the highs due to diffraction which is increased exactly on-axis due to the symmetry and mostly disappears though off-axis, current Genelec and KEF being rare exceptions.
The best I've seen is putting a full range in a properly done transmission line. Still a bit choppy.talking about single drivers & horns, here's a good example for this thread. Comes from another bunch of full-range-driver geniuses: Voxativ

Seems so but I do not want another 'box'.The best I've seen is putting a full range in a properly done transmission line. Still a bit choppy.
The extreme low frequency cone motion in an open baffle will give you a lot of intermod, too.Seems so but I do not want another 'box'.
I did listen to open baffles a few times and liked that "openess". My idea was to put a full-range-driver on an open baffle and then use the receiver's DSP to fix the FR issues and crossover the SB at 80Hz. Easy said.
In practice, I just can't find a pair of reasonably good full range drivers below $1000. (more would be too expensive for such an experiment). Also there seem to be very little data/measurements about the distortion of the full range drivers
