About the Hertz ML 1800.3
LEGENDary woofers
LEGENDary woofers
Is perfect sound possible in the car? Hertz strives to achieve it with their Mille LEGEND Series component speakers. These 7" woofers prioritize premium sound, utilizing the very best technology and materials Hertz has to offer. Do your music justice by incorporating these impressive speakers into your custom system.
Premium Hertz technology
An aluminum alloy speaker basket with built-in venting provides a solid, smart foundation for impressive performance from this 7" speaker. 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 200 watts RMS.
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.

Featured review
I am currently running these midbass drivers in my 2019 Ram Classic. They are in my front doors and sound excellent. I have custom adapters made for them to fit in my doors. I also have used a liberal amount of Hushmat sound proofing to regulate any resonance .

Customer Q&A
Q
Does this driver require an enclosure? And also is the RMS rating per driver or for the pair?
A
The RMS is per driver. These are free air drivers and do not need to be installed into a box with a specific amount of airspace
