DESCRIPTION

The compact 4MR60NDY-4 is a 4″ full range neodymium loudspeaker that can deliver broad frequency coverage and flat midrange response that ensures vocals and instruments to deliver ideal sound to perform well 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 60 watts power handling this driver is capable of remarkable output for its size.

Highlights
  • Nominal Impedance: 4 Ohm
  • 60 Watts RMS Music Power Handling, with a 91 dB Sensitivity, capable of generating a lot sound with a small cone!
  • Broad 90-20,00 Hz frequency range for ultimate flexibility
  • 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 90 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.
