A speaker system includes a speaker box and a speaker mounted thereon. The system comprises collectors for collection of the radio frequency signals, combiners for combining the signals to produce a combined signal, fiber optic transmitter for up-converting the combined radio frequency signals to an optical wave length signal, optical fiber for directing the optical signal, and a heat sink for terminating the optical signal. The storage device includes a primary and a second location. Also, if the threshold is not exceeded, the label of the data unit being closest to the data unit to be classified is assigned to the data unit to be classified.
