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.
