"Box" dynamic speakers have a wider listening window but listeners located more than 30 degrees off axis lose high-frequency extension, overall detail and balanced stereo imaging. Muraudio’s Continuous Curve ESLs ensure that every listener in the room, no matter where they sit or stand, will hear every last bit of recorded musical detail reproduced with the kind of precision, micro-detail, and three-dimensional stereo imaging only an omni-directional electrostatic loudspeaker can deliver. Traditional ESL speakers have extremely narrow vertical dispersion which is reduced the farther the listener is from the speaker. Full fidelity sound reproduction is limited as a result. Muraudio's Continuous Curve ESL panels disperse sound 16 degrees in the vertical plane for full fidelity listening from any position. The sound field gets larger the further you are from the speaker. Muraudio's custom designed low frequency drivers radiate an omni-directional pattern identical to that produced by the ESL panels, producing a seamless integration across the full frequency range, from the deepest bass to the highest harmonic overtones. The award winning SP1 integrates Muraudio’s high output continuous curve projected point source ESL panel with bespoke custom designed six inch aluminum cone drivers to create a beautiful, immersive, panoramic sound stage. The SP1s full range 120 degree horizontal listening window delivers Muraudio’s signature “Sound is Everywhere®” listening experience with contemporary design and luxurious finishing. Electrostatic loudspeakers (ESL) use electrostatically charged micro-thin polymer film suspended between two perforated aluminum plates to reproduce midrange and high frequencies. Muraudio’s Mylar Diaphragm Technology creates enhanced dynamics through improved distribution of acoustic energy across the continuous curve of the ESL, delivering clear, detailed, natural sound. The SP1s virtually weightless, ultra-light electrostatic film moves with speed and precision, producing ultimate sonic accuracy. The SP1s total harmonic distortion is so low that it is comparable to levels only measured in high end amplifiers. The SP1s long throw six inch aluminum low frequency drivers are paired in two independently sealed cabinets, combined with proprietary, tuned inertial reactionary dampers for tight bass response. These ultra-rigid drivers accurately reproduce frequencies below 750 Hz, and move so uniformly that modal resonances are inaudible. Over 6 kg of magnet structure provides the necessary force for deep bass extension, achieving F(-3) = 45 Hz (anechoic). Only professional grade, tight-tolerance premium components are used in the crossover and electronic systems. Air core inductors and Mundorf EVO oil capacitors ensure that critical high frequencies are perfectly reproduced. The SP1’s high voltage transformer uses a precision wide bandwidth interleaved balanced design with ultra-low leakage inductance, delivering clear highs without coloration, operating at low magnetic fields even at maximum power. The SP1’s multi-layer curved cabinet is designed for enhanced stiffness and low resonance. A stable acoustic center is maintained by mounting all drivers symmetrically in a D’Appolito configuration. The SP1 ESL panel and driver configuration are designed to produce a polar dispersion pattern similar to the ESL at the 750 Hz crossover, maintaining uniform tonality across wide horizontal positioning.
