SYSTEM 8:
Audiophile SingleSubwoofer System
This is a perfect setup for the
customer who wants the highest
levels of sound quality but is not
interested in huge bass.
The single 12W3 in the
CS112-W3 provides strong output
and excellent bass quality without
taking up a ton of trunk space. It's
driven by a 250/1 monoblock.
The four XR systems (XR650-CS
in the front, XR650-CX in the rear)
are cleanly driven by the 300/2.
This system is shown connected
to a single pair of line level outputs
at the head unit. In this configuration,
front-to-rear fading is not possible
and subwoofer level must be
carefully preset.
