Which Hertz Mille Pro should I choose?

For the front stage, the MPK 165.3 (4 Ω, 110 W RMS) and MPK 165P.3 (3 Ω, 115 W RMS) are the core 6.5" 2-way component options — the 165P.3 uses a 3 Ω design built for 2 Ω stable amplifiers such as Hertz HCP and HDP models. Upgrade to the MPK 1650.3 for the larger MP 28.3 tweeter and Hi-Contour crossover, or choose the MPK 163.3 for a full 3-way system that adds a dedicated MP 70.3 midrange. The MPK 130.3 is the option for vehicles with 5" fitment locations and no subwoofer space, as its V-cone woofer is designed for wide low-frequency response.

For bass, the standard MP 250 and MP 300 dual voice coil subwoofers deliver 600 W RMS and suit enclosures with no depth restriction. Where boot or cabin space is tight, the shallow-mount MPS 250 and MPS 300 drivers offer 500 W RMS at just 82.6 mm and 88 mm mounting depth respectively. For the simplest install, the MPBX 250 S2 and MPBX 300 S2 enclosures come pre-loaded with the shallow driver and require no separate box build.

Hertz Mille Pro FAQs

Q: What is the difference between the MP 25.3 and MP 28.3 tweeters?

A: The <strong>MP 25.3</strong> is a 29 mm Tetolon dome tweeter rated at 120 W peak, while the <strong>MP 28.3</strong> is a larger 35 mm Tetolon dome rated at 180 W peak and comes supplied with a separate MPCX 2T.3 crossover. The MP 28.3 is also the tweeter used in the top-of-range MPK 1650.3 component kit.

Q: What is included in an MPK component speaker kit?

A: Each MPK kit includes a matched set of woofers, tweeters and passive crossovers — for example, the <strong>MPK 165.3</strong> combines MP 165.3 woofers, MP 25.3 tweeters and MPCX 2.3 crossovers, all sold as a pair ready to install.

Q: What is the difference between the MP 300 and MPS 300 subwoofers?

A: The <strong>MP 300 D2.3 / D4.3</strong> are standard-depth 12" dual voice coil subwoofers rated at 600 W RMS, designed for conventional enclosures. The <strong>MPS 300 S2 / S4</strong> are shallow-mount versions at just 88 mm deep and rated at 500 W RMS, suited to restricted spaces; they also include a mesh grille.

Q: Can I choose between 2 ohm and 4 ohm versions of the subwoofers?

A: Yes — the MP 250, MP 300, MPS 250 and MPS 300 subwoofers are each available in both 2 ohm and 4 ohm single or dual voice coil configurations, so you can match the impedance to your amplifier's output.

Q: Can CEN fit Hertz Mille Pro speakers and subwoofers for me?

A: Yes — CEN has its own fitting workshop in Beeston, Nottingham, where the team can professionally install Hertz Mille Pro speakers, component systems and subwoofers in your vehicle.
