Yes, but just imagine the bone crushing full range bass you get from 3.5mm Xmax. ;)

It's more subjectively but they are crossed over at around 120Hz anyway.
Then kick bins down to around 60Hz.
Then the subs down to around 30Hz.

So not full range in high or low frequencies.

Have you ever thought why you don't see full range drive designs from any credible speaker manufacturer? It's because they have multiple and significant problems and limitations.

Which show 20 dB down by 10kHz.
And which doesn't take the effect of the 2 additional cones into account.
Of course you can value a incomplete simulation higher than the actual measurement but I wouldn't advice doing so.

Sorry you have lost me. Are these your measurements of the drivers actual output or not?

If I put them in a bigger enclosure they will do 40Hz easily and up to 18kHz.
Some even use them for bass guitar.

No they don't do 18kHz in any useable way. The data is there in front of you.

They are useable to about 1.5kHz, at a push, which is exactly what you might expect for a driver of this size.

They do.
The data is in front of you.
In fact I measured them myself and they went up even slightly higher then 18kHz.
But please go on.

From your measurements what was the on axis output in dB at 1kHz and 18kHz?

What was the off Axis, say 30 deg, response in dB at 1kHz and 18kHz?

How much does it vary in between?

Around the same not much difference.
Not possible. Please show your measurements.

Their own data shows a deviation of 10dB on axis and it falls off a cliff off axis. This is exactly what you would expect it to do.

It's seriously flawed as a concept to try and use this as a full range system.

So that shows an appalling 20dB variation in on axis frequency response.
It's more around 10dB though.
If you do nothing about it.
But they go even higher than 18kHz.
Which is not possible ;)

No its not. Look at the graph again. If you ignore below 1kHz is still 17dB

I will repeat. There is a difference between having a response and having a flat response.

It's not possible for a single large driver to have a consistent response from low to high frequencies. Off axis it will be far worse. It's physics. Good sound requires smooth on and off axis response.

It's why no credible manufacturer does this.

You said it's not possible for the Fane to reach 18KHz yet it goes even higher and at adequate output.
Flat response has never been the question.
Sure off axis the HF output is lower but still good enough.
Also you can tweak the FR using enclosure design.

Sorry I wasn't clear, but note I did differentiate early on.

It's not just a requirement to produce output at high frequencies. A driver has to do it on and off axis, at consistent amplitude and with minimal distortion. I would hate to see how the cone is behaving at high frequencies.

This driver fails on all counts.

The off axis is not good enough, its appalling. If you reduced the 10dB excess from the on axis response the off axis would get even worse. It will also be totally ragged.

The enclosure won't stop the appalling peaks in HF response.

This last couple of pages of this thread make me want to listen to Jefferson Airplane's "Surrealistic Pillow" and remember certain "hongos" enhanced days from 1968 in the San Francisco Bay Area.

Mine does.
A little polyester fleece at the right position does the trick.
To me it sounds really good and I'm not a fan of bose if you get my drift.
