Ultimate Passive Monitor

The ESM12 is a full-range low-profile, 2-way, passive monitoring solution with a 12" trans-coil neo woofer and the same 3" NVPD large format compression driver found in our flagship VHD products. The ESM12 also features our revolutionary passive delay line, dramatically reducing feedback. Housed in a professional Baltic Birch cabinet with a protective Polymer coating and heavy-duty grill, the ESM12 can be utilized for FOH applications with the inclusion of a pole mount. Truly one of the most impressive monitoring solutions on the market today, the ESM12 is available in left and right configurations.


  • Professional, Baltic birch construction with wear-resistant polymer coating

  • 127dB sustained output, 130dB peak with very high dynamic range

  • Compact, wedge-shaped cabinet design specifically developed for use in stage monitor applications or low-profile ceiling monitoring

  • Rotatable wide dispersion 40° H x 80° V horn

  • Revolutionary passive delay line

  • State-of-the-art 3" (76 mm) Nitride Titanium diaphragm compression driver with complex geometry phase plug and neodymium magnetic structure for higher output, exceptionally low distortion, and extended frequency response

  • 12" woofer with Super Acoustic Active Impedance Control (AIC), voice coil technology, and neodymium magnetic motor structure dramatically increases force, lowers distortion, and provides increased frequency response linearity

  • Specially designed acoustic fabric covering and protecting the compression driver against liquid spillage

  • "Top-hat" pole mount allows the ESD12M to be used as a conventional loudspeaker
