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.

It takes several days, an eighteen-layer process of primer, paint and protective coatings, along with hours of hand polishing to create the Domain Omni PX1’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.


Each pair of Domain Omni PX1s are hand made to order.  Your PX1s can also be upgraded with custom paint finishes and trim options.
