The crossover can be the strength of your system or its primary weakness. You think a custom-designed crossover that has been designed without your specific enclosure in mind will do the job? Think again!

Our crossover design process uses driver information as well as the enclosure specifications to come up with the right design. It also helps to use the industry's #1 software -  

Here is what you get:

• Recommendation on crossover frequency spread
• A schematic that results from optimizing the response for your specific driver-enclosure combination, in conjunction with constraints such as "overall input impedance should not fall below 3.6 ohms")
• Tailor-made RLC compensation networks designed to account for imperfections in the frequency response for the entire system (driver plus enclosure)
• Energy distribution between woofer, midrange and tweeter for the selected crossover frequencies, with an input conforming to IEC 268-5 specifications (link to ANSI webstore)

What we need from you:

• Specifications of the target enclosure. If you wish, we can design an enclosure to suit the drivers you have chosen
• Ideally, the impedance curves of the drivers measured in the target enclosure without a crossover, for the most accurate results. (DIYers may use Audua Speaker Workshop for this; consider buying our Speaker Workshop jig to make life simple.) However...
• ...even if you don't have these impedance curves, the accuracy of modern driver models allows us to follow an alternate strategy (see Process Flowchart) that uses just the free-air impedance curves plus the Thiele-Small parameters using which we simulate the impedance curves for the drivers in the target enclosure
• Free-air SPL curves of the drivers as specified by the manufacturer
• Any specific preferences you may have, say on crossover slopes (6/12/18 dB/oct)

Prices start at US$35 for a 2-way, 12dB/oct design. This includes one round of iteration: we submit what we think is the most suitable design, you give us your comments (maybe you do not want us to trade off as much SPL to be able to get such a flat response curve and would be OK with a bit of response waviness), we redo the design and submit the final version. For completeness we also provide you the price of a complete, tested crossover prototype.
