Abstract:
An improved loudspeaker system that produces an improved audio quality for stereophonic sound, which can be described as 3D audio. In one embodiment, the improved loudspeaker utilizes at least three stacks of electrostatic transducer cards, with one of the stacks located between the other two stacks. While there is generally some crossover between the frequencies of the stacks of electrostatic transducers, the middle stack will be directed to the lower frequency ranges and the other two stacks will be directed to the higher frequency ranges. Each of the three card stacks will utilize multi-track audio recordings, such as two-track audio recordings, which are modified for each of the three card stacks. In an alternative embodiment, the improved loudspeaker can utilize a conventional voice-coil driver in lieu of the middle stack of electrostatic transducer cards.
