They are bigger than pictures show. Quite deep. AJ gave me the coaxial driver and it is incredibly heavy! I could barely hold it.

Their size doesn't intimidate me
Their price does
But then again, I don't need to put one on a Klippel platform to measure...
Thanks for the update

Looks like they went with a more powerful kt150 tube based tube amp. 65w for that model into 8ohms. Maybe they didn’t want to take a chance with a wimpier amp. 
$34K for a pair of speakers is more than most can afford and more than most are willing to spend on a pair of speakers, but considering all that has gone into them, I would say they are not at all over priced.
Looks like you'd need an engine lift to move them.

The price is not as bad as I expected lol
This and the Dutch & Dutch 15C are pushing the boundaries of what could be a "standmount" speakers. They are huge! The 15C are far more so.
FYI the titling back coaxial driver worked well to point the tweeter at one's ear despite the very small legs under it.

he did indeed.
For that price, can buy my next new car. Not that would spend it on speakers regardless but they would be much more capable if I were willing.
Even if they measure well, more likely would buy something active with room correction (that measures well).

Prices went extremely high for good loudspeakers. It seems that for a planned production target unit count (which may be not very high) all the development and production cost were put into the selling price which is common practice. Unfortunately the final product regarding materials is it not worth the money. Another view is to price according to the usage benefit of a product. In this case the AJ speakers need to be extraordinary in sound quality. Do they?

I understand that some might consider the price of $34,000 to be (too) high.
However, when you look at the competitive landscape—and specifically the niche market for speakers with field-coil drivers—I believe they are actually quite reasonably priced. It is also likely the only model on the market featuring a field-coil coaxial driver, which is developed and manufactured in small batches specifically for this speaker.
That’s not really something that can be done on a budget.

Well, I think that the competitive speakers are also priced too high. And the old tech of field coil in my opinion does not create extra sound quality. Perhaps AJ can explain what is so special when using this tech?
yeah, i've had the dealer going on and on about his line of work and products when I visited for a demo of the mofis. honestly all I needed was the measurements and listening to them in-person. thankfully they do okay on both ends.
anyway most of the speakers now are slim and minimalist, he's like the only few still making big box speakers. i guess there's that too.

Thanks for the video.
This is the first time I’ve actually gotten a sense of how they sound. Even with all the limitations regarding the room’s acoustics, the music selection, and videos in general, I still think they sound promising and are definitely worth a closer look.

The real advantage of field-coil drivers is that the magnetic field is not fixed but can be actively adjusted. This allows you to specifically influence the Bl product, which has a direct impact on efficiency, quality factor, and damping.
You can thus actively influence parameters such as efficiency, Q-factor (Qts), and damping directly within the driver itself, which is essentially an “analog DSP” built right into the motor.
At the same time, the magnetic field remains largely stable even under thermal stress, which can lead to somewhat more consistent behavior at higher volume levels.
Yes, all true. But why is this needed when there exist an adjustment optimum for the loudspeaker in total. With this a chassis with permanent magnet could do the same. Or is it meant that the user may adjust the magnetic field strength at his gusto?

I’m not sure if this is the right way to approach this speaker, because I think a passionate speaker designer was able to turn a personal hobby project into something that will actually make him a little money.
I think it’s great, and I can really relate to the intrinsic motivation behind this project.
But that doesn’t mean I wouldn’t do it differently.
So I agree with you—but I still find the project technically fascinating and interesting.
