One of the worst is a magnesium cone.
Building and establishing the cone geometry and making a moving system with a good balance takes time. In house we have all the machinery for producing the tools for P/P cones. A nice tool for production costs around 7000 to 10000 US$.
There is a more natural and smooth sound [ from the Skaaning that grabs my attention more.
By the by, Ejvind Skaaning freely admits using notch filters in crossovers in the FAQs section of his website. See http://www.audiotechnology.dk. But, in the end it turned out alright, as in "Awwll Raaght!" Maybe "AAWWLL RAAGHT!!!"
The faults can naturally be annulled using notch filters, but these have to be with an equal high Q and therefore far from ideal.
5. I am keenly aware that the very best (and most expensive) motor structure is an underhung motor. I believe there are 2 midwoofers on the planet available with underhung motors. Per Skaaning makes one. I believe the 8" ATC is an underhung.
and the 8" Accuton C2-220/NT6.
Ooooh, that's new . I didn't know this was present. Thanks hubert.
This driver is appealing. With some resistance added to increase the Qes, reasonable bass reach would be possible. The Vas is very high too
But... again... the underhung motor is expensive.
