Xover Pro - Passive Crossover Network Design Software
Xover Pro is an innovative
passive network design program. It can help you design a 2-way or 3-way passive
crossover network, a high-pass, band-pass or low-pass filter, an impedance
equalization network, an L-pad and a series or parallel notch filter. With its
internal Thiele-Small modeling engine and impedance equalization, X•over Pro
provides professional results without requiring you to make complex measurements
of each driver.
Easy to Learn and Use
X•over Pro has many
features that make it 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 243 page printed manual.
Both the on-screen and printed manuals are the best in the industry and include
a "Crossover Network Designer's Guide" and "X•over Pro
X•over Pro also includes a "balloon" help feature
(shown below). When the mouse hovers over a control or label, a small text box
will appear to provide a definition or explanation of the object
Many Popular Crossover Networks &
X•over Pro designs passive 2-way and 3-way crossover networks and
separate low-pass, band-pass and high-pass filters.
Users can choose from 1st, 2nd, 3rd and 4th-order
"ladder" filter topologies. The crossover networks use the popular "parallel"
topology. 2-way crossover networks and separate low-pass and high-pass filters
offer Bessel, Butterworth, Chebychev, Gaussian, Legendre, Linear-Phase and
Linkwitz-Riley filter types. 3-way crossover networks and separate band-pass
filters offer All-Pass Crossover (APC) and Constant-Power Crossover (CPC) filter
The centerpiece of X•over Pro
is its resizable main window (shown below) containing many of the filter
settings for the crossover network and a schematic depicting the crossover
network/filters, impedance equalization network, L-pads and driver wiring. Four
display options are provided for the schematic.
A mini preview graph is located in the upper right
corner of X•over Pro's main window. It displays the amplitude response if the
Thiele-Small parameters are available for the drivers and provides "real time"
feedback of design changes.
A "Filters" and an "EQ" tab are located below the
mini preview graph. They list the values of all capacitors, inductors and
resistors in the schematic and enable users to manually change them. Standard
values can also be substituted for the calculated values of all components in
X•over Pro includes the world's largest database of driver
parameters! It includes both open back drivers (like woofers) and sealed back
drivers (like tweeters). Users can add, edit or delete drivers and the database
can be searched by manufacturer, driver model name, driver parameters and open
back drivers can also be searched based on their suitability for a closed or
Information about the
drivers is contained in the Driver Properties window. It can be entered
manually, imported from a BassBox Pro or BassBox Lite speaker design file,
imported from the CLIO and LAUD measurement systems, or it can be loaded from
X•over Pro's extensive driver database. The Driver Properties window uses six
tabs to organize the information (the "Parameters" tab is shown
X•over Pro scales its capabilities to fit the
quantity of available driver information. A crossover network, filter or L-pad
can be designed with just the impedance of each driver. With sufficient
Thiele-Small parameters the program can also design impedance equalization
networks and it can display the response in its four performance
Using the "Response" tab, the normalized acoustic
response of each driver 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 normalized to the predicted
Thiele-Small response. Its purpose is to improve the accuracy of the Normalized
Amplitude Response graph for those drivers with response anomalies.
X•over Pro provides four graphs
to evaluate the performance of a crossover network design. This includes the
Normalized Amplitude Response (shown below), System Impedance, Phase Response
and Group Delay graphs.
The graphs include numerous options. There are two
graph modes: a combination graph window which displays graphs one at a time for
low VGA resolutions and separate graph windows for simultaneously displaying
multiple graphs for higher XGA resolutions.
Other options include two vertical scales, seven
graph memories, a "net" plot line, a cursor and an export (copy) function via
the Windows clipboard.
X•over Pro includes several
tool windows such as: a Filter Component Resistance Estimator to estimate the
ESR (equivalent series resistance) of capacitors and the DCR (DC resistance) of
inductors, a Parallel-Series Value Calculator, a Color Value Decoder and a Notch
Custom printouts can be
created which include a list of all capacitors, inductors, resistors and their
values, a schematic depicting the details of both the component wiring and
driver wiring, the driver and box parameters and four graphs. A custom logo or
graphic can be imported and printed in the title block.
X•over Pro can open older
X•over crossover network design files (versions 2.1, 2.0 and 1.0). It can also
import driver and box data from BassBox 6 Pro and BassBox 6 Lite.
