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.

*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 avoid 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.

Q & A
3MR40-NDY-4
The 3MR40-NDY-4 is very surprising given it’s small size. Worked perfect in this Plymouth Prowler providing sufficient sound fill from the rest of the car, ran off the factory amplified radio.
These 3″ are running off a 1200.4 getting 200w of brutal power. With the ease of being able to turn off the rest of the system you can hear the quality of 2 3mr40 and the two tw150sd on the doors sound quality.
