THE PASS LABS RUSHMORE IS A UNIQUE MASTER
ART OF WORK, IT WAS DESIGNED, ENGINEERED AND
PRODUCED BY MR. NELSON PASS WITH A DEEP PASSION
AND A VERY LARGE QUANTITY OF EXTRAORDINARY
HIGH VALUE MATERIALS.

THE GREAT GOAL OF THE RUSHMORE :

ALL DRIVERS ARE IN PERFECT PHASE BETWEEN
THEM, IMPOSSIBLE WITH A PASSIVE SPEAKER .
BECAUSE THE PASSIVE CROSSOVER ( INTERNAL OF SPEAKERS )
ALWAYS GENERATES PHASE ROTATIONS BETWEEN THE DRIVERS.

CONSEQUENTLY IS IMPOSSIBLE A PERFECT THREE DIMENSIONAL
REPRODUCTION, PRECISE COLLOCATION OF THE
INSTRUMENTS AND THE SINGER / S INSIDE THE SOUNDSTAGE
WITH THE CORRECT DIMENSIONS ( WIDE, TALL & DEEP ).

IN ACTIVE SPEAKERS, THE DRIVERS ARE CONNECTED DIRECTLY
TO THE AMPLIFIERS, IN THIS WAY, THEY WORK PERFECTLY WITH
THE HIGH DAMPING FACTOR OF THE AMPLIFIER AND NOT WITH
LOW DAMPING FACTOR OF THE PASSIVE FILTER COMPONENTS.

IN A MULTIWAYS ACTIVE SPEAKERS, ALL AMPLIFIERS WORK ONLY
IN A RESTRICTED BAND OF FREQUENCIES ( MORE POWER, MORE
DYNAMIC, MAXIMUM SONIC PERFORMANCE, MINIMUM DISTORTION ).

EACH AMPLIFIER WORKS WITH ONLY ONE DRIVER, WHICH
MEANS ONLY ONE IMPEDANCE AND NOT A DANGEROUS
MIXT OF IMPEDANCES AND PHASES ROTATIONS FOR A FINAL
TERRIBLE COCKTAIL OF SOUNDS.

WITH THE RUSHMORE YOU WILL HAVE THE
MAXIMUM PERFORMANCE OF HIGH RESOLUTION AND
DEFINITION ACTUALLY YOU CAN FIND IN A SPEAKER.

MAXIMUM PERFORMANCE OF TIMBRAL ACCURACY &
TONAL BALANCE WITH A PERFECT 3 D IMAGE
AND DYNAMIC LIKE LIVE MUSIC.

AN IDEAL ULTRA HI-END MINIMALIST STEREO SYSTEM

QUALITY OF THE MATERIALS ( NOT OF MDF ! )

FROM PASS LABS:

“Rushmore” represents 30 years of gestation and over three years

of intensive development,revision and thoughtful listening by Nelson Pass

and the staff at Pass Labs. This is an exceptionally dynamic and tonally balanced

active four-way listening system featuring a 15 inch woofer, 10 inch lower midrange,

6 inch upper midrange and a 4 inch ribbon tweeter.

Fit, finish and build quality is exceptional, and like all Pass Labs product it represents

the labor of a few very dedicated technicians and talented craftspeople.

We believe this to be the most sonically and technologically advanced

listening system available...............

The Rushmore aimed for high dynamic contrast and control with

very low distortion. This was achieved with the finest quality

“strong motor” drivers intimately coupled to single-ended Class A

amplifiers. Each driver (deep bass, midbass, midrange, and high

frequency ribbon) operated over a limited frequency band tailored

to its strengths by a passive filter at the input of each of the four

amplifier channels. The high efficiency (98+ dB/watt) cone drivers

also had very high power handling (up to 400 watts), and the ribbon

tweeter extended from the top octave and far beyond the audio range.

The result was a stunning display of clarity and dynamics. With

each speaker driver enjoying its own amplifier and operated at small

percentage of its capacity, the control was precise and the curtains

of distortion parted to reveal phenomenally subtle inner detail. They

were accurate and musical. They kept their detail and dynamics at

loud and soft levels.

Made from Gabro Aphibolite (a deep-sea granite) and piano-formed

Cherry layers, they weighed just under 400 pounds

each and cost a small fortune.

It’s six years later and we no longer make the Rushmore - the cost of

parts, material, processes and shipping have skyrocketed
