Key Benefits
The slim and shallow design speakers in various sizes can be installed in a wide range of vehicles, providing powerful quality
sound with large magnets and Twin Roll Surround.
✹
Large Magnets
Large magnets provide enough force to drive
even the lowest frequencies.
✹
Twin Roll Surround
The Twin Roll Surround can move in vertically symmetrical amplitudes. This
offers increased total amplitude, better sound pressure, and less distortion,
which enables the speakers to deliver every sound from low to high
frequencies. The shallower edge on the HX8 Series allows smoother motion
for clear, brisk sound.

The woofer cone is reinforced by adding mica to
aramid fiber + carbon fiber composite, to provide
more powerful and dynamic bass reproduction.
✹Shallow & Slim Size
The speakers are designed with a shallower midrange and grille for a
slim mounting depth, which can fit various types of cars.
