Now, I've owned some interesting speakers before but, these have to be one of the most interesting speakers I've come across in quite some time. Why? Well, probably because the mid drivers and woofers are made out of aluminum. By today's production, aluminum may not seem so uncommon. However, back in the 70s/80s, there were probably only a small handful of manufacturers using aluminum cone drivers. Other than Hitachi, I can only think of Bozak using aluminum cones. I am sure they are more, I just can't think of any other manufacturers at this time. The woofers also uses an aluminum voice coil, think vintage JBL.

I won't speculate as I'm not a speaker designer/engineer. However, I can tell you that they sound really good. You wouldn't expect that a light weight speaker can produce such
