As my own waveguide projects have been on hold for a while, I've been helping a friend with his 12-250TC project. He built approx 140L enclosure for it, which is a transmission line. I can't yet comment on how well it turned out, as we haven't had the chance to listen to it in his living room, only in a less-than-ideal workshop space. The most interesting observation so far has been how much damping the pressed steel frame of this speaker affects its performance.
We used sound-deadening matt for car-audio called STP (similar to Dynamat etc butyl rubber matts)
First pic is on-axis and Hor 15 angles of undamped basket:
Pic 2: Damped basket Hor 0 and 15
Pic 3: Undamped and damped comparison, On-axis / Hor 0
Pic 4: Distortion undamped, Hor 0
Pic 5: Distortion damped, Hor 0
Pic 6: Damped in different angles

It seems so! I think bigger 15-300TC could benefit this as well. Heres its response from manufacturer. It has similar chassis.

True, but I was looking forward to trying some new stuff. I wanted to try some high efficiency multiway horn nonsense. Which isn't small, but I decided to have a modest BIB or two for bass and experiment with mid-high horn configurations.'BIB' rules!"Go large or go home!"
Also, a pair of true-to-form BIB for the 15 inch Fanes is about the size of my living room. 😜
Only outside of the frame. When using some warming for it with hot air blower it sticks much better than massaged in cold (sticks still)
Sold those to my brother in law, might suggest he should try it out.
It is a great driver, a shame they stopped making it.
It can still be ordered from Fane directly, but I have no idea if they have stock or that they will accept larger orders only and only from businesses. I prefer the big Fane fullrangers to many of the boutique options. Those are beautiful and probably have strong points, but their parameters are weird and frequency response is all over the place. I'm a little pissed off that the German diyaudio magazines don't test the Fanea. Surely would generate the attention they deserve.
