Ex Machina Quasar MKII

The penultimate studio monitor in Ex Machina’s range, Quasar provides the same flawless imaging, time coherence, detail, and accuracy of its smaller sibling Pulsar, just with even more output and extension from its second subwoofer. The axisymmetric “sub-coax-sub” arrangement also provides an even more coherent hemispherical wavefront, for superior integration at all frequencies, and at any distance or angle within the 90×90 conical coverage.

Custom SEAS Extreme Series Subwoofers

  • Low distortion, long stroke design and rigid aluminum diaphragms provide immense bass precision and reach.

Coaxial Midrange/Tweeter

  • Bleeding edge Composite Sound Metamodal TeXtreme diaphragms: ultralight, ultra-stiff carbon fabrics with optimized fiber geometries to actively control and suppress resonances.
  • Mathematically optimal midrange waveguide shape, underhung surround, and optimized point source acoustic center alignment provides superb off-axis response.
  • State of the art, super low distortion neodymium motor design.


  • Flagship AKM Velvet Sound AK4493/AK5572 based conversion leaves no sonic footprint.
  • Hypex Ncore amplifiers provide gobs of squeaky clean, efficient power.
  • 5th gen SHARC+ DSP hardware can crunch many, many numbers at once.

Sealed Valchromat Cabinets

  • Stiff, dense and well damped, with none of the chuffing or group delay of ported designs.


  • Proprietary, in house calibration code completely flattens frequency, phase and impulse response.
  • Linear Frequency Response: +/- 1db 29hz – 30khz (measured at 30cm cal position)
  • Low Frequency Cutoff: -6db at 24hz
  • Linear Phase Response: +/- 15° 20hz – 30khz
