  • Waterproof treated paper cone and surround stand up to the harshest conditions with true PRO audio performance
  • Full Range Sound, 2-Way coaxial with low frequency speaker combined with 1″ exit Titanium driver, able to respond from 100 Hz all the way up to 20,000 Hz
  • High Output Speaker for 4 Wheelers, Slingshots, and Motorcycles that mounts practically in almost every stock location
  • Common Neodymium motor design for both low frequency and high frequency, reducing phase problems and providing the smallest profile without sacrificing performance
  • 6.5″ High performance coaxial speaker Built to Perform! Capable of high output levels, with separated midbass speaker and horn driver for two amplifier installation.

MT6CX580-NDY-4 - Highlight - Built-in Tweeter

This coaxial features a built-in horn driver with D280Ti titanium diaphragm on a 70° conical wide coverage horn waveguide.

Its horn features a screw-on design to make it easy for the speaker to be serviced. Made from the toughest PM-4 Polycarbonate high wear-resistance material to ensure long life on its treads.

It is capable of reproducing the highest frequencies at easy covering a wide range, phasing up perfect with its low frequency speaker.

MT6CX580-NDY-4 - Highlight - Terminals

This low frequency speaker can keep up with its high frequency drivers thanks to its large voice coil and extreme sensitivity of 95dB, combined with large neodymium magnets for efficient heat dissipation.

It generates an average of 130 dB of output, making it easy to match up with its high efficiency horn tweeter.

Thanks to its special spider composition, no distortion occurs at high excursion, while its silver tinsel lead wire is capable of high current, providing exceptional reliability and dynamic sound.

  *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.

Best 6.5 speakers

These speakers really impressed me hope they come out with a 8in. version. These were game changers for me. Used them on a 21 harely street glide. Not much work required to fit in the stock pods. Also easy to tune very strong vocals.
