the graph does not show that, unless I'm missing something. I see maybe -7-8 dB at 55 Hz, I guess that's alright but to me it matters, I'm not in the market for new speakers, mine have 8 inches and are more expensive (even if they are DIY), but still compact bookshelves and dig much deeper. No matter what people say, I prefer subless setups in my room and that would be too much of a compromise for me. It's not to say these are no good, obviously great measured performance, but content below 60 Hz matter to me. Also, my room is quite large, and I understand compromise is part of the game and you can't have everything.6 1/2" (165 mm) - Midwoofer
Usually does not like small rooms (better 5.25").
55 Hz - 28 kHz (+/- 3 dB). I thought they were going down more.

The tweeter of the 906 breaks up massively very early. The frequency response increase measured by @amirm are the first effects of this. The frequency response increase is not problematic at first and should be inaudible for most people....treble rise starting at 14 kHz? Is it worth EQing?
How can you have harmonic distortion going backwards towards the lows?It can become problematic if the resonance leads to intense harmonic distortions. That means if the resonance is at 24kHz, there could be increased HD2 values at 12kHz, increased HD3 values at 8kHz, etc.

The woofer is made out of the fibers of flax seed. Yeh, the same stuff health food people put in smoothies and such.

If the frequency response measurement was performed up to 30kHz, one would see an intense spike at 22-25kHz.

Since the NFS only measures up to 20kHz, this information is not available to us. If there is much increased harmonic distortion due to resonance, this would also show up as increased IMD - What is considered undesirable.
The resonance at 22-25kHz would also be seen in the impulse response or step response as oscillating interference.
Yep!Yeh, as if I am going to sit there for the 20 hours doing this:

Maybe the person who wrote this, writes the manual for cars in another job and forgot which client he was writing for!
I should go back and chop off the Panther head for this write up!

Yep!
They have a bad tendency to go off-track in terms of marketing BS !

Dear forum users who have a wharfedale diamond 225?) I would send my kit but I live at a great distance, in Russia, on the shores of the Pacific Ocean) and the package from here can easily not arrive to Amir (( thanks for the review 906
For anechoic purposes yes.No. SPL changes 6 dB with halving of distance.
