Paul,
Boundys OBVIOUSLY affect soundwaves... Thats a fact!
It's more an issue of acoustical SPL/position/distance/acoustical space. The
'waves' are just a descriptive element.
CARS have boundries ON ALL SIDES that are reletivly
(compared to bass wavelengths) close and WILL affect the sounds
to some extent no matter WHERE you put a woofer!
But the way they affect one is dependent on fequency as well. In a small space,
such as a car, below the frequency of the lowest axial mode we enter the
pressure region where the driver displacement directly pressurizes the cabin
and there is a 12-dB per octave as freq falls reinforcement.
The donwside is the 60 - 600 Hz region, also size dependent, is generally the
standing wave region; as opposed to 30-300 Hz in a meduim sizd room.
