Pass Labs Rushmore Active Loudspeaker

Audiogon does not list freight as a shipping option.  Obviously, these will be shipped freight because of their dimensions and weight.  It is no problem to ship via any common carrier to any location.

This pair of Rushmore's was the last pair built and are about two years old with light use.  The price has been lowered for a quick sale.  These were $45,000 new.

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.

This unique listening system contains four independent purpose-built low wattage amplification
packages plus a Nelson Pass designed four-way active electronic crossover within each
loudspeaker. Each driver receives amplification from it’s own carefully tailored amplifier using Pass
Labs proprietary circuit topologies. Each amplifier has performance characteristics, which have
been optimized to best suit the assigned driver. Three 10 watt single ended Class A amplifiers
power the two midrange and top end driver, and a 40 watt Aleph-X Super-Symmetric amplifier is
dedicated to powering the woofer.

The careful integration of high efficiency speaker drivers and four low wattage class A amplifiers
has given practicality to a full range “Class A” driven loudspeaker, unique in the ability to deliver
approximately 120 dB of exceptionally wide bandwidth acoustic energy at low levels of acoustic
distortion. No longer is the sonic magic of “Class A” restricted to powering your favorite tweeter.
“Rushmore” brings this amplifier magic to a dynamic nine-octave loudspeaker system.

The precise matching of the four high efficiency loudspeaker drivers and the four independent
channels of amplification has been significantly enhanced and refined by the four channels of
Rushmore’s internal active crossover. Inclusion of the Nelson Pass designed active line level
crossovers have allowed “Rushmore” to overcome the non linearity and high distortion products
inherent in the technology utilized by other manufacturers in virtually every passive crossover ever
produced.

Foregoing the frailties of passive crossovers in favor of active crossovers, quad amping and very
high efficiency drivers makes Rushmore a very different listening experience.

For the listener this translates to a more refined spatial sound stage, increased awareness of
micro-detail and overall greater approximation of sonic reality. “Rushmore” invites and conveys
musicality even when listening outside of the ideal focal spot. With multi channel formats, listening
at the central point of focus is always preferred, but unlike some products, “Rushmore” does not
demand this; freeing you to listen to “Rushmore” casually as well as seriously. This ability to
convey music outside of a very narrow listening field was a Pass Labs acceptance criterion for this
product, because we believe that music should be an integral part of your life, rather than an
exercise in sedentary isolation. Rushmore successfully banishes the necessity of listening critically
from one rigidly defined sweet spot, letting music fill the entire room.
