Andromeda   P Series

Andromeda/Phase III Loudspeaker System

With the success of Phase Linear's amplifiers and pre-amplifiers and after the move to the company's new building in Lynnwood, Washington in 1974, Bob Carver turned his attention to designing a speaker system that would set a new standard in accuracy and listening pleasure. Carver wanted to design a stereo speaker system that, as closely as possible, reproduced the actual aural listening experience of listening to live music.

Carver had devoted a great deal of thought as to why live music sounded the way it did, and how reproduced music failed to duplicate the live listening environment. Live music played in a concert hall was the ambiance Carver wanted to achieve. After months of engineering and prototypes, Carver felt he had reached his goal.

The final system was made up of two large, 24" x 63" x 5" speaker panels, a subwoofer module and an Electronic Motion Control System. The speaker panels each held two 8" midbass drivers, two 4" midrange drivers four 2" cone tweeters and a 1" soft dome tweeter. The subwoofer module had two floor-facing 12" bass drivers. The frequency response was 24Hz to 20K Hz. The Electronic Motion Control system contained "spatial imaging circuitry, frequency tailoring and transient control equalization," according to the Model III Loudspeaker System brochure.

Initially, this speaker system was introduced in 1976 as Andromeda III, but Carver encountered a name dispute, so he changed the name of the system to Phase Linear III for 1977. (Note the two different control modules at left reflecting the change made). With a list price of $1349 when introduced, it amazed listeners when played in Phase Linear dealer listening rooms. The ability of this speaker system to duplicate the actual listening environment for virtually any type of music was an audio breakthrough. Its reputation spread to Europe; there are numerous original owners who to this day will not part with it, and those who did sell theirs regret having done so. The Andromeda and Phase III reputation endures decades later.
