X•over Pro.   $119.00*   Details  |  FAQs  |  Support
X•over 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.

X•over Pro.

  • Compatible with Microsoft Windows 10, 8.1, 8†, 7, Vista and XP.
  • A variety of 1st, 2nd, 3rd and 4th-order filter types are available.
  • X•over Pro's driver impedance equalization networks can compensate for closed or vented box impedance.
  • Dissimilar driver sensitivities can be equalized with L-pads.
  • Designs simple series and parallel notch filters.
  • Includes the world's largest driver database with the parameters for thousands of woofers and hundreds of midrange drivers and tweeters. Drivers can be added, edited or deleted and a variety of search methods are provided.
  • Crossover network designs can be evaluated with up to four performance graphs. All graphs can include the full system response—including the box response.
  • Driver and box parameters can be imported from a BassBox Pro or BassBox Lite speaker design file.
  • Capacitor ESR and inductor DCR can be estimated for several component types.
  • Includes a handy parallel-series value calculator.
  • Includes a convenient component color value decoder.
  • Creates and prints schematics and parts lists.
  • Includes both "balloon" help and extensive context-sensitive on-screen help.
  • Includes an extensive on-screen manual with introductory sections for beginners.
  • Includes a beautifully illustrated 243 page printed User Manual (shown below).
  • Available on CD only (not available for download).

Woofer Tester 2    Details  |  available from Smith & Larson Audio
The Woofer Tester 2 (WT2) by Smith & Larson Audio is an affordable tool that measures the Thiele-Small (T-S) parameters of speaker drivers with professional precision. In addition to woofers, it can also measure many midrange drivers and tweeters. It is equally "at home" on a test bench with a desktop PC or in the field with a notebook PC.

Woofer Tester 2

  • Comprised of two parts: (1) a test module that connects to the USB port of your computer and (2) software to control the test module. It is a self-contained system that requires no additional components for T-S measurement.
  • The test module is small, very portable, and is powered by the USB port (no batteries or AC adapter are required or provided).
  • Has a current source drive with a continuously adjustable sinewave output from 1 Hz to 20 kHz and can measure impedance and phase with an accuracy of 0.01 ohm and 0.1 degree.
  • Many tests can be initiated with just a single button click such as the "Q, Fs test", "Vas Test", and "Vented Box" test.
  • Can measure and simulate Rem/Xem frequency-dependent reactance.
  • Can measure resistors, inductors and capacitors. In addition to measuring their primary characteristic (resistance, inductance or capacitance) the "meter readings" also displays the separate "real" and "imaginary" values so you can also determine the DCR of an inductor and the ESR of a capacitor.
  • Can measure the inductance of speaker cables and test leads.
  • Can measure the non-linearity of T-S parameters versus the drive level.
  • Includes a line-level output which can be connected to a power amplifier (not included) to "exercise" drivers to break in their suspension prior to T-S parameter measurement.
  • Includes a "Design Air Core Inductor" software tool to help you design an air-core inductor.
  • Can estimate the area (Sd) or effective diameter (diam) of an oval driver. (This is needed when measuring the Vas.)
  • Provides a driver and box simulator along with a "Data Overlay" graph to aid with driver design/repair and basic enclosure simulation. The box simulator includes Qport, Qbox, Qleak and Qloss parameters for various kinds of losses. The simulator also includes a basic "room boost" function.
  • Results can be output to a variety of different files, including a "BassBox" parameter file that BassBox Pro and X•over Pro can read.
  • Can be adjusted for varying atmospheric conditions, including the temperature, relative humidity and air pressure.
  • Includes the WT2 measurement module with USB cable, two test leads with alligator clips on one end, a banana jack with 10-ohm calibration resistor, and CD with WT2 software.
