Metal cabinet speakers

I heard a floor-standing set of metal cabinet [aluminum, I believe] speakers at the home of Dan D'Agostino [founder of Krell] a dozen years ago, demonstrated by the man himself.  They sounded fine !  Whether they were prototypes or not, I don't know, but they were designed to be Krell loudspeakers. 

NO cabinets !!  I prefer Open Baffle

geoffkait, notice the two "f"s. Just went to the Audiomachina web site. Interesting design. I like that it is a line source and I like that it goes into corners although that will cause issues with some rooms. Question, what are the 1/2 inch diameter black bumps on either side of the drivers? 
Are the three or so inch drivers run full range and if so I assume the amplifiers are equalized to some degree?

AudioMachina. Not to be confused with Machina Dynamica. 😛

The two ff’s are much appreciated anyway. 🤗

Can I sell you a CD Re-animator? Or maybe some Dark Matter Optical Treatment. I thought you had something to do with AudioMachina. I had never heard of them. So, now I won't offend anyone??? Running a 3 inch driver full range is almost the silliest thing I have ever seen even if they are forming a line array. This is Pipe Dreams meets Bose. Sort of like crossing a rhino with a giraffe. Their horizontal dispersion above 8 kHz will be offal (intentional))) and everything will be Doppler distorted from the bass. Even if you crossed to subs the high frequency dispersion will be so bad that the listening position will be limited to exactly the spot where the beams cross. 
Judging by the lengths they went to to make this speaker it must cost a fortune. Either a SoundLabs or Magnepan 20 or 30 series speaker is going to out perform these things for probably much less money. I don't want to jinx anyone but I doubt these guys will be around long.
