compromise of the Rushmore’s acoustic characteristics as possible.

Like Rushmore and the SR-1 the Pass Laboratories SR-2 started with premiere examples of the loudspeaker driver makers art; the highly regarded Nextel series of drivers from Seas of Norway. Each SR-2 loudspeaker system contains one each of the following SEAS loudspeaker elements;

29 mm soft dome “HEXADYM” tm magnet tweeter

18 cm midrange driver

26 cm long excursion woofer

All of these Seas drivers have very long excursion diaphragms of carefully engineered paper and textile, low mass, under-hung voice coils and substantial copper faraday rings in the motor assembly. These advanced and costly design features in the Nextel drivers assure very low, non-linear distortion and excellent transient response.

The crossover elements are carefully selected premium domestic units, chosen both for their sonic characteristics and technical merit.

Each loudspeaker element and crossover in this single piece 3 way system is hand wired, inspected and tested in the Foresthill California factory of Pass Laboratories, assuring our meticulous personal attention to quality control.

We at Pass Laboratories want you the listener to enjoy this hobby in all its aspects. If you want to do nothing but listen to the music
