Innovative design

For more impactful lows, each speaker 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 provides lows you can feel. The included 3" driver uses the same technology and materials to bolster the midrange with a pristine sound. Superior damping is also key to the sound of these speakers — minimized resonance reduces distortion for a truer-to-life sound.

Included crossovers contribute to the impressive low-frequency response of the woofer, the extensive coverage of the midrange driver, and to a smooth transition to the Tetolon dome tweeter. Hertz builds in tweeter and midrange level controls so you can adjust the mids and highs to match your system.

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 woofer cone surface area than other speakers of the same size, enabling it to move more air. The surrounds are made of 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.

Grilles: The three piece woofer and midrange grilles can be used several different ways. All three pieces (black plastic frame, gray plastic inner grill, and black steel mesh) can be mounted together. The frame and mesh can be mounted without the inner grille, the frame and inner grille can be mounted without the mesh, and the inner grille can be mounted alone.

Tweeter Mounting: Brackets are included for flush mounting, angled surface mounting (60° or 30°), and mounting behind the factory grille.

Tweeter Mounting Dimensions:

  Flush Mount 60° Angled Surface Mount 30° Angled Surface Mount Top Mount (behind factory grille) Bottom Mount (behind factory grille)
Mounting Height 0.437" 1.577" 1.885" 0.965" 0.357"
Depth 0.628" N/A N/A 0.1" 0.708"
Frame Diameter 2.217" N/A N/A 1.971" 1.971"
Cutout Diameter 1.605" N/A N/A 1.306" (minimum) 1.798" (minimum)
Frame Width N/A 1.787" 1.787" N/A N/A
Frame Depth N/A 1.883" 1.562" N/A N/A

Crossovers: Each crossover has midrange and tweeter output level switches; independently choose between flat and +2dB for each. The low pass crossover point is 450 Hz with a 6 dB/octave slope. The band pass output is 450 Hz to 5.5 kHz with a 6 dB/octave slope at both ends. The high pass crossover point is 5.5 kHz with a 12 dB/octave slope. They have screw terminal inputs and outputs that will accept bare wire or spade connectors up to 0.315" wide.

Crossover Dimensions:

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

Customer Q&A

8 questions already asked

I looking to purchase these 3 ways, but I have a question. What would be the HZ setting for the amp to the crossover? I'm not understanding the spec.
victor  Apr 24, 2023
1 answer
The crossover an amplifier for these speakers would likely be a high-pass filter (HPF) set to a minimum of 40Hz. This setting can vary, of course, depending on the nature of your project. For further advice, please reach out to our advisors via online chat or phone at 1-800-324-9695.
zachary  Apr 24, 2023 (Staff)
what is the resistance of the speakers when connected through the crossover?
dauson  Jun 05, 2022
1 answer
Thank you for your question Dauson. The Mille Pro tweeters are 3.9 ohm, the midrange is 3.7 ohm, and the woofer is 2.6 ohm.
hogan  Jun 06, 2022 (Staff)
Can I run these speakers in an active setup? Meaning, can I just throw away the provided crossovers and use my Amp/DSP for setting the crossover for these speakers?
scottyt  Mar 08, 2022
2 answers
Yes, I used the Audio Control DM810 to set up the crossovers and EQ. They love power. Very powerful sound!
thomas  Mar 08, 2022
Yes you can. I did. Front stage is 3 way. Rear stage is 2 way. Full active DSP.
kevin  Mar 08, 2022
Is the milli power 4 capable of driving this 3way component set?
anthony  Sep 15, 2021
1 answer
Thanks for your question. For more information on selecting the best amp/speaker combo 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 between the amp models and help you make the best choice for your system.
kenneth  Sep 16, 2021 (Staff)
Can Hertz MPK 163.3 PRO and JL Audio C3-650 go together/compliment each other? I ask'cause I got the latter ready to install in the front of my brand new car but I have a (odd?) feeling that I should at least have a great and powerful 3-way speaker (set) in the back to really embrace all the hertz and give one (maybe two) of the Rockford Fosgate P3SD412 some 'competition'.

Does this systems crossover have a output for tweeter, midrange and woofer?
carlos  Dec 04, 2019
2 answers
Indeed. It has a single input, then a seperate output for the woofer, midrange, and tweeter. It also as adjustable level for the midrange and tweeter.
thomas  Dec 19, 2019 (Staff)
Yes it does
richard  Dec 18, 2019
Does with system handle 150 watts rms per side, or 150 watts rms combined (left and right)?
quinn  Jun 27, 2019
1 answer
These are rated for 150 watts RMS per side. So a single set of woofer, midrange, and tweeter can handle 150 watts RMS.
