PX2
The PX series was the original proof of concept for the pioneering and state-of-the-art Muraudio suite of technologies.
Muraudio set out to do what many deemed impossible, taking the pure and unparalleled sound of electrostatic technology and created a speaker system unlike any other. The PX2 is the world's only omni-directional, point source, electrostatic loudspeaker. An elegant, contemporary design delivers crystal clear, transparent mids and highs and deep bass extension.
But it delivers beyond the traditional measures – or limits – of what a loudspeaker can be. Due to the groundbreaking way it disperses sound, it adds an extra layer of realism only made possible through Muraudio’s patented approach to recreating the musical performance.
Make your recordings truly come alive, through a uniquely holographic sound experience that is thrilling in a way that simply separates it from traditional two-channel audio. Feel every note more clearly – and every vocal and instrument more exhilaratingly natural within a soundstage that adds a previously unheard-of dimension of authenticity.
The PX2 is the current iteration of the omni-directional, point source, electrostatic loudspeaker. The latest version of the revolutionary transducer that introduced the world to a more lifelike and immersive sound experience than ever before.
“. . . belongs right up there with a small handful of the finest loudspeakers ever made, and it is superior to most of them and all in all, inferior to none.”
Paul Seydor, The Absolute Sound
Muraudio's PX2 incorporates a 360-degree array of Continuous Curve ESL panels with 5,000 square cm of surface area which produces low distortion, high-output sound with perfect coherence and precise response, delivering perfectly uniform 360-degree sound, everywhere in your listening room, and a flawless recreation of the original performance.
The PX2 incorporates Muraudio’s newest Mylar Diaphragm Technology (MDT) for enhanced dynamics through improved distribution of acoustic energy across the continuous curve of the ESL panels. A mylar membrane barely 3.8 microns thick (0.0038 mm) has the same mass as a mere 5 mm layer of air. That’s 250 times less than the moving mass of a conventional midrange speaker cone and tweeter dome array. Muraudio’s virtually weightless diaphragm moves with incredible speed and precision, delivering clear, detailed and natural sound.
"This, friends, is a whole different kind of hybrid ESL speaker. With real bass impact and heft, matched to 3D mids and soaring highs, the sound was exhilarating and head-turning."
Scot Hull, Part-Time Audiophile
For solid bass foundation, the PX2 uses three aluminum cone bass-drivers in a force-neutral tri-axial configuration. Massive magnets, Santoprene surrounds, non-magnetic voice coils, and superior fiberglass coil formers guarantee accurate, dynamic, high impact bass performance down to the lowest octave at any volume level.
Each PX2 integrates the three 25 cm aluminum low frequency drivers in a sealed cast aluminum enclosure. These ultra-rigid, custom designed drivers reproduce frequencies below 450 Hz, and move so uniformally that modal resonances are inaudible.
Over 10 kg of magnet structure provides the necessary force for deep bass extension, achieving F(-3) = 30 Hz (anechoic), while a spatially symmetric magnetic field reduces harmonic distortion.
“Piano, cello, violins, percussion sounded so real. Superb well-balanced/integrated bass.“
Karl Sigman, Audiophilia
The PX2’s advanced crossover delivers deep bass response along with clean, more transparent mid-tones.
Only the best professional grade, tight-tolerance premium components are selected.
Every PX2 is tested and measured to ensure a perfect performance.
Muraudio Speaker Bus
The PX2 features the innovative Muraudio Speaker Bus (MSB). The MSB provides regulated ESL power and active speaker status monitoring to further enhance performance.
The MSB is a bi-directional electrical interface that provides stable DC power to the ESL and displays the operational power state of each loudspeaker with the Condition Monitor Module. The MSB ensures optimal performance of the PX2.
“Murray Harman’s goal to make a statement in the design of omnidirectional, electrostatic loudspeakers has resulted in two speakers unlike anything the hi-fi world has ever seen.“
Doug Schneider, SoundStage!
Muraudio takes pride in investing significant time and effort to ensure that every PX2 attains the highest standards of sound reproduction and lasting beauty. The PX2s woofer enclosure is cast from aircraft-grade aluminum to ensure resonance-free performance. The crown, base plinth and height adjustable feet are milled from solid aluminum billets.
“this extremely ingenious, omnidirectional electrostatic hybrid from Muraudio sounded terrific, even well off-axis. . . superb engineering that has gone into this remarkable creation.“
Jonathan Valin, The Absolute Sound
Finishes
The PX2’s meticulous design and finish is comparable to the finest luxury automobiles. It takes several days, an eighteen-layer process of primer, paint and protective coatings, along with hours of hand polishing to create the PX2’s elegant, stunningly beautiful finish. Choose one of our standard finishes or select custom colours and enhanced finishes such as Pearls or Metallics. For the ultimate personalization you can work with our design team to create a one-of-a-kind finish to your specifications.

"What an experience! I was nearly in tears at that point."
Noam Bronstein, Wall of Sound
"I tried this track out in any number of rooms over the course of THE Show, and this was by far my favorite. . . even during close harmonies that might blur on other systems. I actually found myself starting to tear up a bit at the emotional immediacy . . . ”

“One could move almost anywhere, and the tonal character of the sound would remain effectively constant. This is, of course, what happens at a concert . . .”
