NOLA MICRO GRAND REFERENCE GOLD

Reference Stand-Mounted Loudspeakers (Reference Gold Collection)

 

 

The NOLA Micro Grand Reference Gold is a stand mounted loudspeaker that utilizes the same driver and crossover technology as other Reference Gold models such as the Baby Grand Reference Gold. Unlike most stand mounted speakers, the Micro Grand Reference Gold utilizes our 3½ way UnisonTM crossover, four driver technology -- basically a reduced size version of our statement floor standers.

The driver array utilizes our 45 degree, mirror-imaged concept for midrange and tweeter. The twin 120mm gold magnesium cone woofers are now driven by massive Alnico ring magnets for increased definition, clarity 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 more impact. The 110 mm tri-laminate dipole midrange also uses an Alnico magnet for the lowest possible distortion.

The new true ribbon tweeter is also incorporated which extends 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 speaker.

Latest developments in passive components allow the incorporation of silver / gold / oil polypropylene capacitors to complement the pure copper flat ribbon air core inductors in the crossover. Nordost silver mono-filament wire is used throughout.

The Micro Grand Reference Gold utilizes a built-in double platform base with custom ball bearing isolators to further reduce coloration due to floor borne vibration. The bases are finished in true piano black.

NOLA MICRO GRAND REFERENCE II

Reference Stand-Mounted Loudspeakers (Reference Standard Collection)

The NOLA Micro Grand Reference Series II is a stand-mounted loudspeaker that utilizes the same driver technology and concept as the floor standing Baby Grand Reference and Metro Grand Reference loudspeakers. Driver complement consists of two magnesium woofers, one Alnico magnet open baffle midrange, and one open baffle true ribbon tweeter in a 3½ way UnisonTM crossover design.

The UnisonTM crossover topology, new with the Series II, provides an even more coherent, immediate, and dynamic response from the drivers. Uncharacteristically, the increase in resolution is accompanied by an even more musical presentation. The driver array utilizes our 45-degree mirror-imaged concept for midrange and tweeter.

The twin 120mm cast-frame magnesium woofers operate in an optimum rear vented enclosure. The vent is an oversized, double-flared design that eliminates port noise. The 110mm cast-frame tri-laminate cone midrange uses an Alnico magnet and operates as an open baffle dipole to eliminate enclosure coloration. The open baffle true ribbon tweeter eliminates any kind of diaphragm, as the ribbon is the diaphragm. The moving mass of this design is about 25 times less than any known dome tweeter. The result is effortless detail without hardness. The lack of enclosure in the middle and high frequencies eliminates a large source of coloration.

The 3½ way UnisonTM crossover is implemented on three internal crossover boards for maximum quality. It employs only top quality audiophile grade components throughout, including 630-volt close tolerance polypropylene capacitors and flat wound pure copper coils. Wiring is with Nordost mono-filament silver wire. The crossover boards are hard wired (no printed circuits) for maximum quality.

The Micro Grand Reference Series II utilizes a built-in double platform base with custom ball bearing isolators to further reduce coloration due to floor-borne vibration. The bases are finished in true piano black finish. The Micro Grand Reference Series II brings stand mounted speaker performance to a new level. A dedicated stand is available which provides optimum sound quality.
