Whether you’re designing a custom speaker, fine-tuning an existing build, or just dipping your toes into audio engineering—this Loudspeaker crossover calculator 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 more reliable results, clearer expectations, and a design that better reflects real-world behavior. You’ll see the calculated impedance displayed at the top of the plot for full transparency.
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.
We also stock 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.
