Hertz Mille Pro MPX 165.3 Pro 6.5inch Coaxial Speaker

TWEETER SUPPORT WORKING AS A REAR CHAMBER: sized for low Fs, to ensure a well damped high pass frequency roll-off, allowing low cut-off frequency crossover point.

PRESSED-PULP CONE WITH COTTON FIBERS: combining stiffness and lightweight for a wide frequency response. Cone profile geometrically refined to perfectly match with the tweeter emission ensuring phase consistency in the crossover area.

“BOUNDARY FREE” RUBBER SURROUND: for improved efficiency and wider midbass frequency. (Logo Boundary Free)

OVER-SIZED 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 basket with elegant diamond cutting and featuring the aluminium Hertz logo.
