Alcone makes low/mid drivers (17 cm unit AC 6.5 HE ) with an alu cone.
Prices are fair. Does anybody have experience with these. Do they require complex filters?
Is it better to go for kevlar from Focal or Davis (17KLV6A) ?

I have no experience with AC6.5HE but I have used AC10HE and so far it seems a very good product. If you want to know more you might try some german sites as most Alcones are used in Germany. Good luck.
I have look at the data for the Alcone AC5 and AC6.
To me, the frequency response curves are so bad that I would dismiss these drivers out of hand.
I wish driver manufacturers would quit making DIY drivers that need to be fixed before they can be used.

First I have to say I have no own experience with Alcone Drivers but I have several German DIY speaker magazine issues with various tests of single Alcone drivers as well as complete speaker kits of them.
Also for me they seem to be fair priced and they are solid engineered drivers - no junk drivers.
The frequency response alone tells not the hole truth about them.
Admitted, the aluminium cones have a nasty higher frequency peak and ringing but this is the case for almost any alu cone driver and as it is normal for many rigid cone types as kevlar, carbon, ceramic and the like. Actually below the nasty high frequency peak the Alcones are very linear and behave quite well as also can be seen from the waterfall diagrams.
To give good results those drivers need a high slope lowpass x-over to give enough attenuation or/and maybe a notch-filter in order to remove the high frequency peak.
