Judging from the crossover layout and input transformer taps, these compontents are from the Sentry I, not the Sentry IA which was 8Ω only.   The drivers look like the SP-12 and T35, but the woofer frame is wrong and there are no markings on either driver to indicate the actual model.   

 These components were removed from a Mono monitoring setup in a TV broadcast Control Room.   All are in very good condition.   

  • Cast frame 12 inch woofer with a Whizzer cone
  • Compression Horn Tweeter and driver
  • EV Sentry 1000 crossover
  • Baffle board with grille 

 

Here are some of the specifications from an old EV Sentry I brochure.  Please note that these measurements include a cabinet:

  • Frequency Response: 30 - 20,000 Hz
  • EIA Sensitivity Rating: 49 db
  • Impedance: 16-150-600 ohms
  • Power Handling Capacity: 20 watts
