Mille Pro MP 250 D2.3 / D4.3 by Hertz
Discover the Mille Pro MP 250 D2.3 / D4.3, a 10-inch subwoofer from the renowned manufacturer Hertz. This evolution of the successful Mille Legend is an outstanding example of compact size and high performance. A highlight is the special manufacturing of the speaker cone, using the same process as the Legend series. The subwoofer offers thoughtful technologies and materials, such as the Boundary Free Surround technology for higher sound pressure and a particularly robust aluminum non-resonant basket construction. The Mille Pro is thus the perfect companion if you want the Hertz sound experience in your car.
