Information Cubed - Rockford Fosgate punch 40X2 Operating & Installation

Information Cubed

The data acquired in the testing procedure is then graphed in the form
of a 3-dimensional cube, hence the name PowerCube.
The Phase Angle is expressed on the horizontal axis, the Output
Voltage is presented on the vertical axis and the Impedance is
displayed on the Z axis. Output Power, in watts, is listed on the left
hand side for each impedance at each phase angle.

What is an Amplifier?
An amplifier by definition is a voltage generating device, recreating
the signal which is input to it identically but with increased volume.
It will be connected to a reactive load (the speaker). The impedance
of this load and phase of the signal passing through the load will vary,
dependent upon the frequency of the input signal (music).
Therefore, a perfect amplifier will be able to maintain the same output
voltage regardless of load characteristics and will not alter the signal
it is reproducing. A perfect amplifier when measured by the Audio
Graph PowerCube would present data that forms a perfect cube.
Unfortunately, amplifiers are not perfect. The laws of physics gener-
ally prevent it. A great amplifier is about the best one can hope to
attain.
As you can see by the PowerCube and as you will experience by
listening, your Punch amplifier is a GREAT AMPLIFIER!
