BassBox Pro - Box Design Software
BassBox Pro™ is a state-of-the-art
speaker enclosure design program. It is used around the world by professional
and amateur speaker system designers to design worldclass speaker boxes. BassBox
Pro is very versatile and can be used to design speakers for a wide variety of
applications including home hi-fi, home theater, car, truck, van, pro sound
reinforcement, recording studio monitors, stage monitors, PA, musical
Easy to Learn and Use
BassBox Pro has many
features that make it very easy to learn and use. For example, when the program
is first run, a Welcome window (shown below) will appear to help you configure
the program and introduce you to its on-screen manual.
The on-screen manual (shown below) is extensive and
contains most of the same information as the beautiful 364 page printed manual.
Both the on-screen and printed manuals are the best in the industry and include
a "Box Designer's Guide", "Sample Designs" and "BassBox Pro
BassBox Pro also includes a "balloon" help feature
(shown below). When the mouse pointer hovers over a control or label, a small
text box will appear to provide a definition or explanation of the object
Box Design is as easy as 1-2-3
many ways to begin a speaker design with BassBox Pro, including the use of its
innovative Design Wizard. In general, speaker design involves the following
- Enter the driver parameters such as Fs, Vas and
Qts. BassBox Pro's driver database contains parameters for thousands of
- Calculate the box volume and tuning. This is very
easy with the program's helpful "Suggest" button. It will cause BassBox Pro to
recommend a box that will produce a smooth bass response.
- Evaluate the performance with the graphs. This can
include the effects of the acoustical environment. For example, BassBox Pro
can estimate the in-car response in the graphs to show how the speaker will
sound to passengers inside a car.
Each box design can be saved and re-opened or re-used
later. As many as ten different designs can be open at the same time. Box
designs can also be duplicated so that driver or box information does not need
to be re-entered.
BassBox Pro includes a
powerful Design Wizard (shown below) to help new users quickly design a speaker.
It can start with either the driver or the box and then it will walk you through
BassBox Pro as it prompts you for information in an orderly progression. In this
way it serves as a "smart" assistant to help you use the
The centerpiece of BassBox Pro
is its resizable main window (shown below) that includes a summary of all open
designs. Up to ten designs can be open simultaneously.
A mini preview graph is provided for each design to
show its amplitude response. These preview graphs are automatically updated
whenever a design is altered, providing "real time" feedback. A small picture
beside each mini graph displays the box type that has been selected (closed,
vented, bandpass or passive radiator). A summary of the driver and box
parameters is listed in a text box.
Largest Driver Database
Pro includes the world's largest database of driver parameters! Users can add,
edit or delete drivers and the database can be searched by manufacturer, driver
model name, driver parameters or suitability for a closed or vented
Information about a
driver is contained in the Driver Properties window. The driver information can
be entered manually, imported from another BassBox Pro or BassBox Lite speaker
design file, imported from the CLIO or LAUD measurement systems, or it can be
loaded from BassBox Pro's extensive driver database. Like many windows in
BassBox Pro, the Driver Properties window uses tabs to organize the information.
Three of its six tabs are displayed below. The first illustration shows the
"Configuration" tab where the number of drivers and their mechanical and
electrical configurations are set.
Notice above that the mechanical configuration
settings include compound or isobaric and push-pull.
The second illustration shows the "Parameters" tab
containing the driver's Thiele-Small and electromechanical parameters. "Net"
parameters are displayed when more than one driver is specified. If the driver
has a dual voice coil, separate parameters can be entered for each of the three
voice coil wiring methods (separate, parallel and series). An "expert mode" is
available to analyze driver parameters for errors.
The third illustration shows the "Dimensions" tab
containing the driver's outer shape, piston type, dimensions and volume

Design Many Different Box Types &
BassBox Pro models a wide variety of box types including closed,
vented, vented with active HP EQ filter (B6), single-tuned and double-tuned
bandpass and passive radiator boxes as shown below:
Twenty-two different box shapes are available as
The information about the
box is contained in the Box Properties window. Three tabs are displayed below.
They depict a single-tuned bandpass box with three chambers (using two drivers).
The first illustration shows the "Box Design" tab where the box type, shape,
volume, tuning and dimensions are set. Notice that it includes a scaled drawing
of the box. This drawing automatically updates in "real time" whenever the box
The second illustration shows the "Vents" tab which
contains the vent parameters and dimensions. The vent parameters include the
number of vents, their shape and end type. If a passive radiator box is
selected, this tab will appear as the "Passive Rad." tab.
The third illustration shows the "Parts List" tab
with a scaled drawing of each box part, a list of dimensions and, if
appropriate, cut angles.
Not shown are the "Description", "Damping" and
BassBox Pro accepts two
different types of acoustic data. It can be entered manually or imported from
several popular measurement systems (B&K, CLIO, IMP, LMS, JBL/SIA Smaart,
MLSSA, Sample Champion and TEF-20). This acoustic data is added to relevant
graphs to improve their accuracy.
The acoustic response of the listening environment is
entered into the Car/Room Acoustic Properties window (shown below). For example,
the acoustic response of a motor vehicle interior can be entered to show how a
speaker will sound to a passenger inside a car.
The normalized acoustic response of the driver is
entered into the "Response" tab of the Driver Properties window (not shown). The
driver's acoustic response is normalized to its predicted Thiele-Small
BassBox Pro provides nine
graphs to evaluate the performance of a speaker design. The Normalized Amplitude
Response, System Impedance, Phase Response and Group Delay graphs are provided
for small-signal analysis. The Custom Amplitude Response (shown below), Maximum
Acoustic Power, Maximum Electric Input Power, Cone Displacement and Vent Air
Velocity graphs are provided for large-signal analysis.
The graphs include numerous options. There are two
graph modes: a combination graph window which displays graphs one at a time for
computers with low VGA resolutions and separate graph windows for simultaneously
displaying multiple graphs for computers with higher XGA
The graphs can display the "pipe" resonance of vents,
the estimated piston band on-axis amplitude rise of a driver and the estimated
diffraction response shelf (of selected box shapes) that can result from the
front-panel circumference of the box.
Other options include two vertical and two horizontal
scales, seven graph memories, cursor and an export (copy) function via the
Custom printouts can be
created which include the box and driver parameters, a three-dimensional box
drawing with internal and external dimensions, a parts list with two-dimensional
box part drawings, dimensions and cut angles, an English fraction-to-decimal
conversion table, wiring diagram with an external network parts list and nine
graphs. A custom logo or graph can be imported and printed in the title
Driver and passive radiator
test procedures are included in the program to help you measure most
Thiele-Small parameters. (Requires test equipment such as: sine wave generator,
frequency counter, power amplifier, 1000 ohm 2-watt resistor, voltmeter,
ohmmeter, test box.)
A passive network
(high-pass, band-pass or low-pass filter, impedance EQ network and/or L-pad) can
be entered or imported from X•over Pro to display the system
BassBox 6 Pro can open
speaker design files from BassBox 6 Lite and older versions of BassBox (versions
5.1, 5.0, 4.0 and 3.0). Passive network information can be imported from X•over
