B51-4 4" Loudspeaker Combo Package FC104T72/51-4 by Atlas Sound is a very beautiful loudspeaker assembly that combines sound performance of a full range 4" high compliance loudspeaker without compromising convenience and economy of a factory-assembled loudspeaker, transformer and baffle. Unit gives wide-angle sound dispersion to achieve desired coverage with fewer loudspeakers in distributed systems.

Each of these loudspeakers employs a 10 ounce ceramic magnet and a damped, high-compliance cone to provide excellent low-frequency reproduction with smooth extended response. Package includes factory-mounted, dual-voltage 70.7/25V or 70.7V transformer and round grille with screw mount installation.


  • Power Taps 70.7V/25V
  • Speaker Type High Compliance
  • Dispersion 135 / -6dB, 2kHz
  • Sensitivity 94dB (at 1W / 1M)
