System Type 2
System Description
In this system type, both the woofer and tweeter are mounted apart at different dis-
tances and angles relative to the listening position, with the tweeter as the closest driver.
While this type of installation is undoubtedly the most common today, some may not
consider it to be an ideal situation for imaging due to the large difference in distance. In
general though, a high tweeter location is thought to be advantageous for improving
perceived height and width of the soundstage, as well as achieving a strong high fre-
quency output level. In typical OEM woofer locations, the woofer is nearly always at an
extreme listening angle, while the tweeter is only slightly off-axis. The woofer axis be-
comes more extreme the farther away it is, if there is no build out of the mounting angle.
It just so happens that the same high-pass and low-pass configurations work for the two
most typical installation types, only requiring a slight change in tweeter level to more
properly match woofer output. It is important to note that the tuning of the settings below
considers the best balance between driver and passenger listening positions, so all
distances and angles are referenced to the nearest side.
• Type-2A is consid-
ered to be the most
common installa-
tion type, as the
woofer is typically
mounted low in the
door in the factory
position.
• Type-2B is essen-
tially the same as
above, but as-
sumes the woofer
somewhat farther
away than is typi-
cal. This will ac-
commodate differ-
ent vehicle types
as well as kick
panel mounting of
the woofer.
