Hertz MP70.3 50 Watts RMS 3" Mille Series Midrange Speakers
- SKU #: 01175
Features & Specifications:
The MP 70.3 car audio mid-range speakers featuring Neodymium double magnet inside the coil produces an enthralling mid range, perfect to combine with the powerful mid-low of the MP 165P.3 woofer as well as with the detailed high range of the MP25.3 tweeter. The 20 mm coil of the MP 70.3 maximizes the dynamics; the V-cone® profile enhances off-axis dispersion and the Boundary Free Surround allows for a wider extension towards the low frequency range.
