The stuff of LEGEND

Is perfect sound possible in the car? Hertz strives to achieve it with their Mille LEGEND Series MLK 165.3 component speaker system. This set of two woofers, two tweeters, and two versatile external crossovers prioritizes premium sound, utilizing the very best technology and materials Hertz has to offer.

Premium Hertz technology

An aluminum alloy speaker basket with built-in venting provides a solid, smart foundation for impressive performance from the 6-1/2" woofer. Hertz employs a "Boundary Free" rubber surround with its enhanced pressed pulp and cotton fiber woofer to move more air with accuracy. The woofer's V-cone design improves dispersion and helps provide lows you can feel. Superior damping is also key to the sound of these speakers — minimized resonance reduces distortion for a truer-to-life sound driven by up to 150 watts RMS of power.

Premium components

The premium components of this crossover system contribute to the impressive low-frequency response of the woofer and to a smooth transition to the stunning work of the Tetolon dome tweeter. Hertz builds helpful tools into their deluxe external crossover system which include tweeter level adjustment and “Hi-Contour” adjustment which allows you to select the tweeter's high-pass crossover point, depending on tweeter distance and positioning.

The Hertz philosophy

Hertz believes that a good speaker should reveal the emotional power of the music you love. That's a high bar, but with their commitment to using premium components and boundary-pushing design, they're more than up to challenge. Comprised of music lovers, Hertz is committed to optimizing your car's sound system for total audio enjoyment.

Product Research


Size Classification Note: Some manufacturers, including Hertz, call this size woofer a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size as a 6-3/4". Please enter you vehicle information to confirm fit in your vehicle.

Boundary Free Surround: This technology provides more cone surface area than other speakers of the same size, enabling it to move more air. The surrounds are made of butyl rubber, ensuring thermal and mechanical linearity.

Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and computer software to do large-scale analysis of drivers in motion, helps Hertz optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.

Tweeter Mounting: The ML 28.3 tweeters are designed to flush mount using the included clamps. They can also be mounted to many factory tweeter brackets using the M3 threaded insert on the back of the tweeter housing. The tweeters are permanently mounted in their housings.

Tweeter Dimensions:

  Flush Mount
Mounting Height 0.586"
Mounting Depth 0.7"
Frame Diameter 2.112"
Cutout Diameter 1.9"

Tweeter Level: Three different positive wire terminals offer tweeter output level options, -2 dB, 0 dB, and +2 dB. Hertz recommends +2 dB when the tweeters are mounted off-axis (relative to the listeners) and 0 dB when the tweeters are mounted on-axis.

Hi-Contour: A 2-position switch in each crossover adjusts the tweeter output contour, and thus the crossover point. Hertz recommends the 3.5 kHz (On) setting when the tweeters are mounted off-axis and the 4 kHz (Off) setting when the tweeters are mounted on-axis.

Slope: The slope of the high-pass and low-pass outputs is 12 dB/octave.

Wiring: The crossover inputs and outputs are screw terminals and will accept bare wire or spade connectors up to 0.3" wide.

Crossover Dimensions:

  • Width: 5-3/4"
  • Height: 1-5/8"
  • Depth: 4-1/2"

Customer Q&A

3 questions already asked

150 watts RMS for the pair or for each speaker? I am confused.
[ Half Staff  Mar 12, 2022 ]
1 answer
That is for each component speaker. One woofer and tweeter wired together, will handle 150 watts RMS.
[ Paul  Mar 15, 2022 ]  Staff
Will the MLK165.3 run with the Hertz HDP5 on 3 - channel mode.?
[ Danny  Mar 21, 2020 ]
1 answer
I will let you know that it is running fine on 3 channels. Before i had it on 5 channel (front+rear+sub 4x75,1x550 watt rms).Because i don't use the rear speakers i have decided changing to 3 channel, And the Hertz mlk 165.3 sounds so much better and louder.
[ Danny  Mar 28, 2020 ]
What is the difference in these and the 1650.3?
[ Jason  Oct 03, 2019 ]

Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget.

The 1650.3 set are insane. I put those in my front door and I bi-amped them with a 500watt amp and they absolutely rock. I know that the magnet is significantly better on the 1650 than the 165, and I know that the 165 cannot be bi-amped as well. The 165 set are great in my rear doors, but are totally overwhelmed by the 1650s getting more juice up front. Not sure what setup you have or what you're aiming for, but everything I throw at the 1650.3 set shocks me. I'm loving my setup with these.
