Metal cabinet speakers


I like the idea of a very strong inert metal cabinet. Besides Magico, Steinheim and T+A.. who else makes metal cabinet speakers?

TAG McLaren Calliopes are made of aluminum alloy and they pre-dated Krells’ LAT Series by several years. I think they were really onto something but it was all for naught. I have a pair of Calliopes and I feel fortunate to own them; probably one of several dozen pairs that were sold in North America before TAG went belly-up. They don’t do deep bass but they are superb in every other aspect.
Geoffkait, when was Klipsch founded. I do not know the History of Audio Machina as to when they first released their product but unless they come up with some low end products that regular folks will like they will be history just like Nearfield Acoustics. If I suggest a linear array speaker I will go with ESLs or ribbons. Maggie 20.1s out performed the Pipe Dreams in every way except volume and the same is true with these Audio Machina things. The Maggie ribbon tweeter is the best tweeter made even better than ESLs due to its wonderful dispersion characteristics. If you look at the physics stacking dynamic drivers is a silly endeavor. There is no driver narrow enough to work. A dome works fine as a point source. Maggie's ribbon tweeter is 1/4" wide and radiates over 100% of its surface area. It is also long enough to function as a linear array over its entire frequency range. Perfect. The only sad part is the woofer is not...long enough. Because the speaker is a bit over 6 feet tall it functions as a line source down to somewhere between 150 and 200 Hz. The best way to deal with this is to make the speaker 7'10" tall so that it abuts an 8 foot ceiling. Then it will be a line source down to 1 Hz. Magnepan thought about doing this but they thought it would decrease their Market I guess because it would make the speaker more expensive. Good magnets are not cheap. Pity. Subwoofer systems just do not function well up at 200 Hz. So, when I set up Maggies I keep the subs point source and jamb them into the corners. I cross at 100 Hz. I guess I am rambling.  
As far as I know Klipsch was founded just prior to the American Civil War.
