FABRICATION is a discussion of the various box designs and
their final fabrication.
1. First, measure the trunk volume that is available
( measure L" x W" x H" ). Use MATH CALCULATIONS if
necessary to convert from cubic inches to cubic feet.
Use the volume measurement ( cubic feet ) in all of
your BLAUBOX calculations.
2. The rectangular box design is the simplest box to
build and is recommended for most installers. The
tubular design is becoming popular due to the cos-
metics and general ease of construction. The wedge
shape maximizes the volume in most trunk areas but
becomes more complex to build with the various angled
cuts.
3. All of the above designs can be modified using the
MODIFY DIMENSIONS command under Screen #2. The
dimensions can be changed until a box fitting the
exact trunk area is designed. By working through
BLAUBOX backwards, you can then determine the frequency
response once the box volume is determined.
4. The PORT command under Screen #2 allows for changing
the port tube lengths and diameters hopefully using
what PVC stock is available in house.
5. Most importantly, using DRAW BOX, you are able to
print out a drawing of the box. Verify all dimensions
before you start to make sure the box will fit the
speaker. A 15" woofer with 12" side walls is going to
require substantial creativity to make it fit!
More information and examples on this subject are in the
BLAUBOX user's manual.
