the how and why of bass in your BMW
Fully 1/3rd of all recorded music is below 80Hz (this is called bass!) Almost
no interior component speaker can reproduce sound below 80Hz without
high levels of distortion (some CAN reach to around 60Hz, but that's really
the lower limit). The cheap paper drivers BMW uses in their audio systems are
no certainly no exception to this rule.
Why? High output bass production requires that a speaker physically
moves a great deal of air relative to what's required for higher frequencies.
This air movement is accomplished in either or both of the following two ways:
- High Excursion: Excursion refers to how far a speaker can
move in or out from its resting state. The smaller the speaker, the larger
the amount of excursion required to produce bass output -- and vice versa.
However, a small driver with high excursion is far less efficient than a larger
driver with lower excursion (require TONS of power from the amplifier) and
is very impractical in a car audio situation due to the space required in
front of such a driver to accomodate the movement. (It's also difficult to
design a very high excursion driver that remains accurate at the limits of
its movement).
- Large Cone Surface: As the cone surface area of a speaker
increases, the more air the driver can move -- and the more efficient a driver
becomes relative to a speaker with smaller cone surface area. However, the
additional mass of such a driver requires more power and a more stout motor
structure (the components that control the speakers) to keep the driver controlled
and accurate.
Both solutions do require substantial power output from the amplifier
driving them, but power can be expensive. For cost savings reasons,
manufacturers will produce a larger coned driver out of lightweight material
(i.e. paper) to minimize power requirements. Unfortunately, the resulting lightweight
subwoofer is flimsy, and when combined with low power yields muddy, fuzzy bass
at moderate volumes and distortion at high volumes. This is PRECISELY the case
in BMW's Premium (DSP) Audio System in the BMW X5.
And if you don't have the Premium System, because your stock amp and speakers
(and even high quality component speakers and an aftermarket amp) are small
in size, share the same lightweight construction, and are low in power, you'll
get the same fuzzy bass, just less of it.
And so, an effective, high power subwoofer solution is needed. But
with the BSW x108, it doesn't have to come with sacrifices.
