Please elaborate. I've found that these are designed and built in the USA, with quite good cabinet construction, intertwined solid copper internal wiring, beefy drivers, and a very good crossover network. Pretty much everything that a good speaker is made of. The few reviews that I have found of these, they say they are excellent performers and have a very detailed output with clarity that does not cry foul with harshness, as do most of the Japanese "kabuki" speakers from this era do.
