Couldn't Load Pickup availability
The Hertz Mille Pro MP 165P.3 is a 6.5" (165 mm) midrange woofer rated at 100W RMS / 200W peak with a 3 Ohm impedance. It is part of the Hertz Mille Pro range, designed for high-dynamic systems and optimised for use with 2 Ohm stable amplifiers including Hertz HCP and HDP models.
Key specifications
- Size: 165 mm (6.5")
- Power handling: 100W RMS continuous / 200W peak
- Impedance: 3 Ohm
- Frequency response: 45Hz – 4.5kHz
- Voice coil: 25 mm (1") pure copper on Polyamide former, 14 mm height
- Cone: Pressed pulp with cotton fibres, V-Cone® profile
- Magnet: High density flux ferrite, 95 mm diameter
- Weight: 1.2 kg per speaker
MP 165P.3 PRO: 165 (6.5) mm (in.) woofer, 200W, 3 Ohm
The MP 165P.3's electro-acoustic parameters are tuned for pure, solid mid-bass performance in high-dynamic systems.
- Pure copper voice coil: wound on a Polyamide former for high power handling and very low intermodulation distortion of vocals.
- Exponential V-Cone® profile: geometrically optimised for linearity and dispersion in the mid frequency range.
- "Boundary Free" rubber surround: improves efficiency and widens the mid-bass frequency range.
- High density flux ferrite magnet: combined with very low carbon content iron plates for low distortion at high power levels.
- Basket: low mounting depth, acoustically transparent aluminium alloy construction with diamond cutting detail and an aluminium Hertz logo.
The voice coil's 14 mm height and 3 Ohm nominal impedance maximise compatibility with the Hertz HCP and HDP amplifiers and all 2 Ohm stable electronics. The 95 mm ferrite magnet enables +/-4.5 mm voice coil linear excursion for consistent control at all power levels.
The Boundary Free surround moves a greater volume of air, and the V-Cone® profile improves off-axis dispersion — a key factor in real in-car listening conditions. The aluminium alloy basket neutralises unwanted vibrations. If you're looking for a more accessible 6.5" component option, the Hertz Dieci DSK 165.3 is a 2-way component set at 80W RMS.

About the Hertz MP 165P.3
From our tech experts at CEN
The Hertz Mille Pro MP 165P.3 is a pair of 6.5 inch (165 mm) midbass woofers, not subwoofers. They handle 100 W RMS and 200 W peak at 3 ohms, cover 45 Hz to 4.5 kHz, and use a V-cone pressed pulp cone with cotton fibres, a Boundary Free rubber surround and a 95 mm ferrite magnet.
Who it suits
High-dynamic active systems running 2 ohm stable amplifiers, where the 3 ohm load draws more power. Hertz pairs it with the MP 70.3 midrange and MP 25.3 tweeter. For a standard 4 ohm woofer, choose the MP 165.3.
Our tech experts advise
Check your amplifier is happy at low impedance before choosing the 3 ohm version. They are woofers only, so run them with a low-pass. Each weighs 1.2 kg. Installation is priced per vehicle, so get in touch.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Why is the Hertz MP 165P.3 rated at 3 Ohm?
A: The 3 Ohm nominal impedance lets it draw more power from Hertz HCP and HDP amplifiers and other 2 Ohm stable amplifiers, while keeping full control thanks to its +/-4.5 mm linear excursion.
Q: Is the MP 165P.3 a full-range speaker?
A: No. It is a mid-bass woofer covering 45Hz to 4.5kHz, designed as the woofer in a component system rather than a full-range speaker.
Q: How much power does the MP 165P.3 handle?
A: It is rated at 100W continuous and 200W peak power handling.
