The Domain Omni PX1 is purpose designed for operation with audiophile grade power amplifiers. The audio signal is separated into low and high frequency channels with a precision passive crossover network utilizing the highest quality components including only air-core inductors and polypropylene film capacitors. The PX1 can be bi-amplified if preferred or driven from a single amplifier. The PX1 is a nominal 8 Ohm system up to about 5 KHz with minimum impedance of 2 Ohms load at 20 kHz due to the capacitive load of the electrostatic panels. In music there is very little spectral power above 5-10 kHz and as such, the PX1 is fully compatible with 4-8 Ohm rated amplifiers. The audio step-up transformer delivering the critical audio signal to the electrostatic panel is a balanced-interleaved typology comparable to that used in the world’s finest tube amplifiers.

Muraudio changes everything with the introduction of the Domain Omni ESL, a 360 degree point source, omni-directional electrostatic loudspeaker.

The Domain Omni ESL and the complex technology it incorporates has been the subject of intense research and development for the past twelve years. Electrostatic loudspeaker design is recognized the world over as the best way to accurately reproduce the original sound. Extremely low distortion, true linearity, and outstanding frequency response are some of the key advantages. At the same time, traditional implementations have been limited by lower output levels and high directivity (especially at high frequencies).

Muraudio’s reference level Domain Omni incorporates patented High Output Continuous Curve ESL technology, precision engineered LF drivers, industry leading components, stunning design and high grade finishes to create a one of a kind loudspeaker that will transform the way you think about high end audio.

Hear high fidelity, immersive, natural sound with pinpoint imaging and seamless coherency. Clear, full, pure sound. No matter where you are, you’re in the sweet spot.

The Secret to Authentic Sound

Creating life-like sound lies in the theory of what we call Coherent Polar Movement.

When you enjoy an actual concert experience, the sounds you hear are in more ways a reflection of the original source than they are directly from the source itself. Sound from an instrument or voice is simultaneously reflected off of numerous surfaces before it reaches your ears. The problem with traditional front firing speaker designs, whether electrostatic or electrodynamic, is that the sound is never produced that way. Virtually all speakers have specifications related to the “on-axis” response. That means you need to be in a very specific location to hear the output as intended. Anywhere else, and you are out of “the sweet spot”.

The Domain Omni ESL produces sound that is acoustically as near a perfect recreation of the original recording as possible. Using electrostatic technology and purposefully designed LF drivers that deliver clean and full low frequency bass extension, through Coherent Polar Movement the Domain creates a uniform, 360 degree full range sound field. That means what you hear is as close to the ambience and presence of the original performance as you could ever imagine possible.

That’s why at Muraudio, we say “Sound is Everywhere”. Audition the Domain Omni ESL and experience audio like you never have before.

To accurately reproduce and image recorded sound, the optimal design for a high frequency transducer is considered to be a point source. ESL designs to date have included simulated point sources, planar and curvilinear designs. All are dipolar, producing a limited sound field.

What Muraudio set out to do was create the world’s first actual large area spatial point source using the undisputed accuracy of electrostatic film technology. In short, the world’s first monopole ESL that radiates uniformly outwards, without producing rear wave cancellation effects.

Years of research have resulted in the development of the first electrostatic panel that is curved in multiple directions. The design offers horizontal dispersion of 360 degrees, and vertical dispersion of 16 degrees. This allows a listener to hear everything as it was recorded, anywhere within the expansive sound field.

The geometry and forming process of the perforated aluminum panels ensures high acoustic output. This important development along with curvature in multiple directions is the subject of numerous patents.

Muraudio’s High Output Continuous Curve design is the world’s first monopole ESL.

LF Drivers

The Domain Omni’s three bass drivers perfectly complement the sonic accuracy of the electrostatic transducer. While over 97% of the audible range is produced by the ESL, the lowest 3% is critical to completing the tangible experience that a moving bass passage creates. The results were impressive.

The aluminum cone driver moves so uniformly that modal resonances are inaudible. A formidable santoprene surround provides linearity at maximum excursion, and a non-metallic coil former guarantees low motional loss.

Over 10 kg of magnet structure provides the necessary motor force needed for deep bass extension, achieving F(-3) = 30 Hz (anechoic) in a sealed enclosure, while a spatially symmetric magnetic field reduces harmonic distortion. This means you experience accurate bass reproduction at all volume levels.


Developing an entirely new type of loudspeaker requires engineering precision and adherence to strict design goals. Built by a highly qualified team, every component of the Domain Omni ESL has been thoroughly researched and produced using exacting manufacturing processes.

Patented methods are used to meticulously form each of the 55,000 holes that make up the perforated aluminum structure of the Continuous Curve Electrostatic Transducer. From a liquid state, aluminum is cast to create the sealed driver enclosure. The crown and feet are carved from solid aluminum, and polished to a perfect finish.

Aluminum cone LF drivers are mounted in a force neutral tri-axial configuration to produce unrivalled low frequency response. A rear wave acoustic absorber is placed within the ESL membrane to create an ideal monopole source. Finally, the high performance electronics are installed in the base of the enclosure. The result is a masterpiece of engineering and design unlike anything ever seen or heard.
