Crossover Design with Leap Software
Let Madisound custom design and build your crossovers
Crossover design has significantly evolved in the last decade. In the past you had to start with a theoretical design and then spend weeks tweaking until you came up with a crossover that sounded pretty good, but probably was not as good as it could be.
Madisound has now developed the art of crossover design, providing the customer with a fully developed filter system in a fraction of the time necessary using older methods.
Madisound begins by taking all driver response and impedance measurements in our anechoic chamber using the Audio Precision measurement system.
We then export this data into the Leap filter analysis program by Linearx. With the Leap program we can plot what would be an ideal curve for each driver, and then use Leap to try different filter values against the actual driver response curves, continually selecting those parts that bring the actual curve to that of the ideal curve. We then look at the total system response curve and select parts to match the ideal system response.
The result is a flat response curve, to the limits of the selected driver responses. This method can be repeated for impedance correction to create an ideal impedance magnitude response. The finished design is excellent, and a good value!

This is not an assembled crossover. Assembled crossovers vary in cost, depending on the quality of the components that are selected.

To place an order for a Leap design, Madisound we need to know the following:
- What drivers are you using? They must be Madisound stock items.
- What are your box volumes, or do you wish us to determine them for you?
- Are the drivers surface mounted, or routed into the cabinet for a flush mount?
- What slopes (6dB, 12dB, 18dB, 24dB) would you like us to design for, or would you prefer we choose?
- What quality of inductors will you use? We will model using the DCR of the coils.
The following printouts are provided with each Leap design order (actual documents are laser printed hard copy):
