WinSpeakerz - Additional Screen Shots

Additional screenshots of WinSpeakerz v2.0.

This new page is where you'll specify the baffle width when modeling diffraction loss. This page is also where you will enter the corner frequency of your vehicle (or room). You can find the corner frequency of Your Own vehicle (or room) using the following formula:

Corner frequency = 565/D where D = the largest cabin dimension
Example: 565/8.55 = 66

You can also adjust the Q of the vehicle transfer function to best fit a measured response.

The System Editor is the place to make adjustments to various system parameters such as box loss Q, isobaric factor, write notes on the System as well as make custom adjustments to the System's particular driver.

The WinSpeakerz Crossover Calculators

WinSpeakerz also provides specialized calculators which support the design of passive crossovers, attenuators, and impedance compensation networks.

WinSpeakerz has six types of crossover calculators: 1st, 2nd, and 3rd Order Butterworth, 2nd and 4th Order Linkwitz and 1st Order Series with adjustable damping. They all operate in the same manner with the user entering the impedances of the tweeter and woofer and specifying the crossover frequency. The WinSpeakerz Crossover Menu includes a Resonance Compensator Calculator, Inductance Compensator Calculator (Zobel) and a Tweeter Attenuator Calculator.

The WinSpeakerz Box Calculators

The Rectangular, Trapezoidal and Bandpass box calculators are also located under the Box Menu and on the Toolbar. There are input fields for Driver Displacement, Bracing Displacement, Other Displacement and Box Volume added by filling. The WinSpeakerz manual goes into much greater detail about each of these features.

In addition to calculating the volume from arbitrary enclosure dimensions, WinSpeakerz will calculate the dimensions from the volume. You can enter box dimensions and the box volume will be calculated, or you can enter a volume and WinSpeakerz will calculate the dimensions using the golden ratio. The Box Calculators have locks in each of the box dimension fields for holding certain dimensions constant while allowing other dimensions to float.

The Trapezoidal Box Calculator includes an angle field to specify the angle of the side of the enclosure. The default is 15 degrees when you first open the trapezoidal box calculator. WinSpeakerz takes the V(B) from the Box Parameters window and calculates the dimensions for a 15 degree trapezoidal enclosure according to the golden ratio.
