Whether you’re designing a custom speaker, fine-tuning an existing build, or just dipping your toes into audio engineering—this tool is here to help.
Unlike simpler calculators that rely on DC resistance alone, this one goes a step further: it computes component values based on the driver’s actual impedance at the crossover frequency. That means a design that better reflects real-world behavior. You’ll see that calculated impedance graph displayed at the bottom of the page along with the transfer function of your selected filter once you have filled out the data fields.
That said, it’s not intended to replace full-featured crossover design software like Leap—or our own bespoke crossover design service. If you need precise acoustic modelling, driver blending, or enclosure simulation, we’d love to help. Just reach out or explore our custom services.
We also stock a range of loudspeaker components—so once you’ve dialed in your values, why not poke around the shop? You might just find the perfect component to bring your design to life.
