1. A video and audio system that uses a TCP/IP LAN (local area network) using TCP/IP as the communication protocol, comprising:

  • a networked audio source node device that further comprises a video device;

    a plurality of network speaker nodes, said network speaker nodes couple to said networked audio source node device via a TCP/IP LAN using TCP/IP as the communication protocol;

    an internet interface coupled to said network speaker nodes via said TCP/IP LAN using TCP/IP as the communication protocol;

    a network control server coupled to said network speaker nodes via said TCP/IP LAN using TCP/IP as the communication protocol; and

    a legacy converter and controller coupled to said TCP/IP LAN using TCP/IP as the communication protocol that couples a legacy source to said TCP/IP LAN, said legacy converter and controller further comprise an embedded controller with memory and which is programmed to function as a web server that uses TCP/IP as the communication protocol;

    wherein said network speaker nodes further comprise;

    an embedded controller with memory and which is programmed to function as a web server that uses TCP/IP as the communication protocol;

    a pre-amplifier that couples to a digital signal processor and adjusts and filters the analog audio signal and an amplifier that couples to said pre-amplifier and amplifies the analog audio signal, said pre-amplifier further comprises an electronic crossover for frequency division;

    speaker sensors that include a microphone used for receiving and or gathering control information that enables internal auto adjustment by frequency separation to enhance speaker protection and performance from said network speaker nodes surroundings, said control information is sent to other devices on said TCP/IP LAN; and

    a speaker/microphone driver that couples to said amplifier and provides the external connection to the speaker/microphone components for the analog audio signal.
