In 1985 extensive research began to determine just what was required for low frequency reproduction. It was not known at the time that the duration of this study would take more than 6 years and would cover every avenue of psycho acoustics, wave theory, etc. In 1992 this new technology was patented. The new technology is called the Acousta-Reed and is incorporated in every model we produce today!

The Acousta-Reed is a way to acoustically couple mass to the energy radiated by a driver. We have seen examples of the Acousta-Reed concept all around us for many years. It is simply an extension to moving mass such as the relation of the acoustical chamber of a guitar to its strings, or the saxophone body to its mouthpiece reed. The Acousta- Reed also provides time shift to the low frequency energy produced by the back of the bass driver and extends the useful range of the system. The Acousta-Reed's memory (suspension) is 1000 times more linear than that of a high compliance speaker; therefore the low frequency transients are far superior to conventional design.

With the inception of the Acousta-Reed and our small drivers, the Digital Phase AP series loudspeakers are unmatched in their ability to reproduce natural, uncolored, smooth sound and full three- dimensional imaging. In addition the system provides superior power response, transient response and linearity. A testament to the advancement and quality of Digital Phase Loudspeakers is their high acclaim and recognition in the industry.
