The 160 mm magnesium gold bass drivers utilize massive Alnico ring magnets for increased clarity and definition and even lower distortion. The solid copper phase plugs are gold plated to provide damping by the soft gold layer over the solid copper. This concept eliminates any last vestige of coloration from these drivers. Bass is tighter with improved definition.
We have also developed a new true ribbon tweeter. This new driver extends the high frequency response to 100 kHz. This extended bandwidth provides an increased sense of "reality" over the whole range including the bass.
The lack of any enclosure in the midrange or high frequency range eliminates any possible enclosure coloration in this critical region -- something that cannot be achieved with any kind of box loudspeaker.
Newly developed polypropylene/silver/gold/oil capacitors provide increased resolution for the 3½ way UnisonTM hand wired crossover. The crossover is implemented on three separate crossover boards, internally mounted. Flat copper ribbon coils and Nordost Mono-Filament Silver wire are used throughout.
The Metro Grand Reference Gold utilizes a double platform ball bearing isolation base to further reduce floor-borne vibrations which tend to "muddy" the sound.
The Metro Grand Reference Gold is ideal when the expansive musical sound of the Baby Grand Reference Gold is desired -- but in a smaller room.
