Overview

The SR-1 is a 4-way speaker using the best drivers available; the highly regarded Nextel series from Seas of Norway. Each SR-1 loudspeaker system contains one each; 29 mm soft dome “HEXADYM” tm magnet tweeter, 18 cm midrange driver, 22 cm mid-woofer driver, 26 cm long excursion woofer.

The SR-2 is a more compact 3-way version of the SR-1. Each SR-2 loudspeaker system contains one each; 29 mm “HEXADYM” tm magnet tweeter, 18 cm midrange driver, 26 cm long excursion woofer The SR-2 was optimized to make best use of smaller and more acoustically demanding environments that may not support large floor standing speakers.
One of the significant attributes of the SR-2 is a spectacular blending of the three drivers into one coherent voice even at listening positions normally associated as very near field and too close to the speaker to be considered optimal.

Each loudspeaker element and crossover in these speakers are 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 it’s aspects. If you want to do nothing but listen to the music then we say sit back and enjoy the “SR” Loudspeakers for what they do.

About the brand

Based in Foresthill, California, USA, Pass Labs was founded by Mr. Nelson Pass, a well known figure in the high end audio community.

Although Pass Labs has only been around for a decade, they have collected more awards than many companies who have been around a lot longer.

Mr. Pass is known for unique and innovative, as well as practical, circuit designs. Pass' first designs, in the Aleph line, were single-ended pure Class A solid state. The current Pass Labs "X" series amplifiers use a distortion canceling balanced audio signal circuit, and continue to receive critical acclaim.
