1.1 Low Noise Floor

A key element in achieving the sonic goals mentioned in the previous section is significantly reducing the noise floor. The term "noise floor," in this discussion, refers to the stray uncorrelated energy that is produced as an artifact by the loudspeaker. This manifests itself in latent energy below the musical signal and in deleterious phase noise. Both must be reduced to an absolute minimum.

Through new proprietary technologies in the elements of the crossover circuitry, the noise floor has been lowered by more than 25 dB over any existing design. The low noise principle has also been applied to cabinet design and construction, where new techniques in resonance control and careful attention to diffraction and driver coupling effects further reduce stray acoustic energy.

The overall sonic result is a three dimensional spatial presentation of the instruments recorded within the context of their original environment. The

background seems black and devoid of contaminating energy, while each individual instrument breathes into the space in which it was recorded. Truly low level details, such as wall reflections from the original recording site, are clearly and concretely apparent. The entire recording environment, whether natural or artificial, can now be transposed in toto to your listening room.
