SB introduces their models slowly so eventually we will see alu cone Satori, i'm sure of it.
Maybe they'll produce a new Satori range with a type of ribbed paper cone...

That appears the first one of the line. Honestly, nothing impressive. Standard voice coil (long), pretty heavy cone for its Sd, low sensitivity and Qts for ported use. Weird parameters. Maybe designed for tiny ported loudspeakers that can have some bass output but I am missing the point in this driver, really. The graphene coating - not sure of what it does besides marketing - the breakup is at 6.5Khz which is not that high and is obliterating.

I doubt putting a couple thin Graphene skins on the Al cone will make a huge difference in cone behavior

Anti oxidization? I'm still looking forward to seeing Magico like all graphene cone unit.

Isn't it that vast majority of loudspeaker manufacturers currently aim for exactly that weird parameters? If it is bad or good it depends mostly on correct implementation of that driver in end system and you can't judge it just looking at the specs. All specs are improved over earlier design. Some people from the industry reacted lively for its introduction. I hope the price won't be steep I am affraid it most, knowing other alternatives I predict hopeless future for this driver if its price stays considerably higher than current Excels.

They do because most music is mastered in such a way there`s little dynamics headroom left. So you can use drivers like this one. I fail to see the point in this driver, really, but everyone, including me, does have subjectivity.

Sales, sales is the point. Still reputable but already too expensive company tries to recover its splendour trying not to share Scan-Speak distress. In order to do that, they decided to offer 'exciting' graphene tech which for me is 100% marketing blurp. Real improvements to this driver in terms of linearity and mechanical stability are hidden from sales point of view and have nothing common with micro-thick and mega-expensive nanostructures.

Absolutely. I wonder how long it will take for real improvements ot show up, like graphene nanostructure cone, ironless loudspeaker motors (Kharma I believe has it, plenty of patents out there, even Renault have one...), advances in suspension design...

Improvements? Not quite, generic and ubiquitously used loudspeaker motor design has already reached technological and performance plateau. Moving subsystem materials and design techniques as well. Rather further price drop and market flooding of decent drivers, some for steal price, is expected. What is Kharma? Renault makes loudspeakers?

Kharma Loudspeakers. Manufacturer. Renault has a patent with the University of Maine (yes, in the USA) of such motor.
