The ZM70 is particularly suitable for sophisticated car audio systems where  sound quality ,  installation options  and  visual appearance  are key.

Special features of the SIGMA ZM70:

Full-range cone construction : The  SIGMA ZM70  is a  full-range speaker  that features a  cone  with  on-axis response  up to and beyond  17 kHz . This means that the speaker accurately reproduces even the finest details and high-frequency nuances with great precision, resulting in extremely clear and natural sound.

Advanced Mounting System : A standout feature of the ZM70 is its  advanced mounting system , which allows the speaker to be used in a variety of installation scenarios. The speaker can be used in both  custom interior solutions  (such as A-pillars) and in  tight, standardized mounting holes  in the vehicle. This versatility makes it easy to integrate into almost any vehicle.

Vented voice coil : The ZM70 features a vented  voice coil  that reduces  distortion  and  compression  at high volumes. This ensures significantly more precise and undistorted reproduction, even during intense sound events or at very high frequencies.

Low-loss suspension (high Qm) : A  high-quality, low-loss suspension  with  high Qm  ensures particularly  detailed and dynamic reproduction . This means that the speaker remains extremely precise and differentiated even at low volumes or during extremely fast changes in sound, which greatly increases the  dynamics  and  detail  of the music material.

Design and appearance : The ZM70 is supplied with  high-quality accessories  to ensure that it impresses at the highest level, both acoustically and visually. The scope of delivery includes two different grille options: Hexagon grilles  for a modern, eye-catching look.
