magnet drivers. I think that the permanent magnet version of the Western Electric 555 compression driver is at least as good
~~~~~~~~~~~~~~~~~~
My tech believes a good (= heavy duty) ferrite is every bit as good as a lighter weight Nd/Alnico/FC motor system. But as you say if given a choice, you would opt for FC.
Whereas I would opt for Nd.
That aside,, I’m beginning to believe most important component in a FR is the cone material.
There are Bamboo fiber/TB Banana fiber/Kanuf fiber/Fostex Paper /some Voxativ paper/mineral composite/AER Paper coated treated/Cube Sandwiched paper/mineral composite mix/Mark Audio Wood composite/Davidlouis Someone on DIY has argued wood IS PAPER.. well duhh yes, but it ain’t paper paper. Its wood,, something like bamboo wood fiber, exact same wood fiber as a few of Vox’s higher end/higher priced models. Each material will offer a slightly different sound resonances throughout the entire mid fq.s 200/300hz through to the 4k/5khz. Low bass 40-80hz and highs say 10k-15khz these will be very close in all materials just listed.
Sure magnet structure ~~Cube’s 81 Nd/at a combined weight of 1480 grams is stunning, not to mention their *8secret mix magnetic motor also looks like it has POWER,, AER’s massive magnet motors, as well as Vox’s huge ferrite magnets. So all top lines offer pretty much excellent magnetic field power to drive the electrons through the cone /whizzers/phase plugs. Its the cone material composition which will determine how each high end manufacturer’s speaker will voice the critical midrange resonances and nuances.
IOW each will have a particular **house sound**. Its this **house sound** which is what makes the voice either to our liking, or not so well liked. ~~Come material determines a FR voice in the band width which is our main concern in FR speakers. Not bass, not highs.
These bands are only secondarily of importance.
