By the way frequency graphs only tell 1/8 of the whole story.

The W3-1878 has great Qts, better construction materials, good BL etc

You should looking into the Newer Fostex FF 85wk 3 inch fullrange drivers. Nothing that I have heard can touch them at any price point! CR

The thing is we all can read specs but it's HEARING the speakers which finally counts, so this is why i'm looking for people having an experience with those speakers ... who can describe(hopefully) how they sound.

Some would argue that distortion, phase, impedance, and amplitude (vs frequency) measurements is what counts. At least for a designer. But ultimately it has to sound good yes, however the ear can't provide an absolute reference nor can it point you in the right direction when optimizing.

I've spent far too much time tuning systems via trial and error. It started making me crazy so now I measure.

Hi Matt, unfortunately the measurements don't tell 100% of the story. For example a speaker might produce certain frequencies while doing frequency sweeping but when playing all the frequencies at the same time, some frequencies might disappear due to I don't really know what.

I tried it in the studio, testing a small 2" speaker with no enclosure. I soloed a small high frequency band which targeted a nasty sibilance and the sibilance could clearly be heard.... but when the whole song was playing altogether, the speaker could not produce the sibilance.

This is why I think that specs can tell the story to some extent but finally amp, DAC, speaker designers have to ultimately use expert ears to fine tune their products.

This could be reason why a resonance may not show up with pink or white noise.
Intermodulation-distortion and Doppler-distortion ??
The offending bandwidth could be hidden with phase distortion.
But 1 driver will not be better than another in this regard by a listening test. all full rangers with suffer from IMD when trying to cover too much bandwidth.
As far as choosing a driver, if the HD profile is clean and the driver breakup
is tame or high enough not to notice (above about 12 kHz) then it's a good choice.
I wish Mark K. did a HD measurement of the TB driver....it would tell us a lot more.

Rk,
I only see an image of driver in unusual flower shaped cabinet. Where are your measurements again?
Thanks.

I found only this measure. I'm not sure in what conditions was made.
If I find a moment of time will do you measure.
Have a nice day
