Pass Labs Introduces SR1 Loudspeaker, Four-Way Floorstanding Listening System for Audiophiles

Uncompromising Speaker Emphasizes Performance, Accuracy, Power

Pass Laboratories, Inc., an audio innovator renowned for its unique high-performance products, introduces the SR1 Loudspeaker, a high-performance listening system using the highest quality drivers available.

The new SR1 is Pass Labs’ second loudspeaker, following and replacing the Rushmore, its exceptionally dynamic introductory speaker. The new SR1, a four-way floorstanding system, is equally uncompromising. Its highly refined sound stage, deep awareness of micro-detail, and effortless dynamics deliver superb, accurate musical reproduction.

The SR1 has been designed to harness the classic “mass controlled piston” model, in which the speaker’s radiating surface behaves as a rigid surface. This yields a well-defined characteristic in the spectral region where the sound is proportional to the electrical current through the voice coil. At the boundaries of this frequency band, the response falls off in a predictable manner.

The trick to making it work is to find a perfect piston driver. The cone surface must maintain its shape over the frequency band without breaking up into resonant vibrational modes. The suspension and motor system must remain linear with high excursion. Most speakers, however, allow the cone to flex in a way that gives some extension at higher frequencies at the cost of an irregular response in the frequency response and phase performance.

The SR1’s drivers are the best available, and employ Nextel-coated cones and a Crescendo tweeter from the renowned Seas of Norway. They present the best combination of low distortion, high dynamics, and predictable performance. It takes a minimum of four sizes of these drivers to span the SR1’s 10-octave audio range without significantly leaving the “piston” region.

The SR1 uses dual enclosures. A large bass enclosure with ten-inch and eight-inch drivers handles the bottom four octaves, and an adjustable smaller enclosure carries the midrange and the tweeter. The Seas of Norway drivers are complemented by a set of crossover and equalization electronics created to elicit the drivers’ best performance.

The SR1 is available as a bi-amplified or quad-amplified system, complete with active crossover filters. Upgrades and conversions between the systems are easily accomplished, and the speaker is compatible with a wide range of power amplifiers. The impedance does not dip below 4 ohms, and the sensitivity is approximately 90 dB for a 2.8V input.

The SR1 Loudspeaker will be available in February from authorized Pass Labs dealers at a suggested price of $25,000.
