Selecting the KSS6704, we built and embedded a large speaker into a flocked-finish A-pillar.
Moreover, by adding the KSC270 to the KSS6704 system—refined and perfected as our own original—
we have evolved it into an astonishing 3-WAY setup that goes beyond conventional expectations.

By clearly separating the roles of the high, mid, and low-mid ranges,
overlapping sounds and muddiness disappear,
and each individual note appears in the space—three-dimensionally, with precise placement.

Vocals float forward,
while instruments are positioned with left-right spread and depth,
creating a music stage on the dashboard that feels less like “listening” and more like “stepping into” the performance.

This is not just an additional speaker.
It is 3-WAY tuning that can only be realized by our shop—because we know the KSS6704 inside out—
based on the assumption of a high level of completion.

This is no longer an upgrade—it’s evolution.
Once you experience it, you won’t be able to go back to 2-WAY—
so convincing, it’s a truly formidable 3-WAY experience.
