The DAP NRG-15 is a passive full-range loudspeaker rated at 550 watts peak (150 watts continuous RMS). It uses a 15” woofer and a 1” compression driver. With a sensitivity of 96 dB/W/m, the NRG-15 comfortably plays up to 118 dB with peaks of up to 130 dB. The compression driver is coupled to a rotatable horn with a directivity of 90°x 60°. The woofer has a low cut-off point of 50 Hertz (-6 dB).The sturdy, lightweight plywood cabinet has a double-angled top hat (0° and 5°), allowing you to point the cabinet downwards when mounting it on a pole. It uses 4-pole speaker in and thru connectors and offers an additional 4-pin terminal connector, which is especially useful for permanent installation applications. To get the most out of the NRG-15, we recommend using a 4th order high-pass filter at 50 Hertz and adding an NRG series subwoofer.
