PRV Audio 3MR40-NDY-4 3" Neodymium Midrange Loudspeaker

Features PRV 3? Full-Range Neodymium Speaker 3MR40-NDY-4 PRO Audio Midrange 40 Watts / 4 Ohm The compact 3MR40-NDY-4 is a 3? full range loudspeaker designed to perform in portable speaker systems, line arrays, or even car audio applications where weight and space limitations comes as a major factor in the project. With 91 dB efficiency and 40 watts power handling this driver is capable of remarkable output for its size. Nominal Impedance: 4 Ohm 40 Watts RMS Music Power Handling, with a 91 dB Sensitivity, capable of generating a lot sound with a small cone! Voice Coil Diameter: 0.75? Strong neodymium motor, increases efficiency on a compact design. Very low profile loudspeaker, fit it in tight spots easily! Super well balanced frequency response from 120 to 20,000Hz, making this a MR. Do-It-All with high fidelity sound as a midbass, midrange or full-range speaker. GENERAL SPECIFICATIONS Nominal Diameter 3 (76.2 mm) Nominal impedance 4 Ohm Nominal Power Handling* 20 Watts Continuous Program Power (RMS)** 40 Watts Max Peak Power*** 80 Watts Sensitivity 2.00V at 1m 91 dB Recommended Hi Pass Crossover For Full Power Handling 160Hz 12db Per Octave Crossover Frequency Response 120 20,000 Hz Voice Coil Diameter 0.75 (19 mm) Voice Coil Wire CCAW Voice Coil Winding Depth 4.8 mm Former Material Polyimide Magnetic Gap Depth 4 mm Frame Material Stamped Steel *Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range. **Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to provide a clean signal without clipping or saturation. ***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
