About: PRV Audio 10W1000-NDY-4 10" Woofer Loudspeaker 500W RMS - 4 Ohms

PRV Audio’s 10W1000-NDY-4 Neodymium Woofer Loudspeaker was carefully crafted to reproduce a natural, smooth sound while remaining dynamic. The PRV Audio 10W1000-NDY-4 is the evolution of our mid bass loudspeakers, our R&D department pushed the output limits on a mid bass driver, creating a unique sound reproduction. 

To get superior fidelity, the special composite cone is built with non-pressed paper for reduced break-up, delivering a smooth frequency response and a low moving mass, increasing the efficiency of the speaker.

The 10W1000-NDY-4 is an extremely efficient 10″ woofer from PRV Audio. To stand up to the use and abuse of the professional sound environment we designed a 3″ CCAW voice coil that is wound inside-outside on a fiberglass former and features a generous 18 mm winding length for extended Xmax and less distortion. (with a suggested 80 Hz, 12 dB/octave high pass filter in place)! Its powerful optimized neodymium motor is vented to provide excellent cooling.
