I decided to just start a new thread discussing some questions that came up regarding the use of this driver in a project.

I'm listening to this driver in a 3way with the Illuminator tweeter and Scan Speak 26W. Quite simply this mid is the most transparent mid I've ever heard......
Well I guess at the price you should get something for the money!
Here's the Illuminator Air Circ tweeter distortion at around 85-90db:
Here's the Scan Speak 26W 8 ohm:
This is on par with the best I've ever seen. Also the Frequency response was very flat. Sorry no picture of that right now.
By the way; yes the test was around 85-90db in this box:
It has a very linear FR and VERY low harmonic distortion profile. Plenty of Xmax to boot. There's not much better out there than the 26W. By the way this is the aluminum cone version. The paper cone version looks interesting as well, but the FR doesn't look as nice as the 26W from the graphs I've seen. Might have to test that out for myself sometime.
Thanks for the props Jim! Are you going to Dayton this year? Maybe if time permits I can bring the new Lineup Maxx L16mk2
As for the C82, if they use the same motor as the used in the past I doubt it comes remotely close to the C90's performance. Want to send a pair for me to test?
I think JonM best answered this in his response below. Also note that even though the cone materials are not the same, the sonic signature is close because of each driver's low harmonic distortion profile and linear response. I do not detect timbre mismatching, which I deduce is because of those qualities. Also, I doubt the Accuton tweeters can hit the transfer functions I used for this speaker without audible distortion.
As for the roundover, I ended up using a 28mm chamfer which works well to minimize diffraction.
It's the 26W woofer, so not much different than other 10" drivers with low distortion. It will work well in a 60L box tuned below FS. The bass is lean and tight. It is fast and without a hint of boominess. Just clean sound. If the track is bass heavy, so will the sound get portrayed through this speaker. One of the trade-offs was getting the deepest bass response (selected the 10" for that reason), and it had to fit in a reasonable sized box. Dual 8" drivers would work well, but the impedance would likely be lower with the parallel connections and would be limited to a higher F3. This speaker will hit the high 20s in room.
