Crossover PCBs

Custom boards I've designed which make it quick and easy to assemble the crossovers for many popular DIY speaker designs.

Most of these designs have come via request, so if you are interested in PCBs for a popular speaker design that you don't see below please just ask.

Links to the PCB kits I currently have available on eBay:

Don't see a PCB kit that works for you or need something more custom? You can have it commissioned!

See the Crossover Design/Assembly page for more info.

I've created detailed assembly instructions for the DIY Sound Group crossover PCBs but the same basic assembly principals apply to these PCBs as well.

You can find those instructions here.


  • Q: What is included with these PCB kits?

A: You get a single or pair of circuit boards (depending on the kit) for the specific speaker design chosen, along with terminals blocks, standoffs, screws and an instruction sheet to assist with assembly.

  • Q: Do these kits include the crossover components?

A: No, you will have to purchase the crossover components separately.

  • Q: What tools are needed to assemble one of these PCB kits?

A: You will need a hot glue gun with a couple glue sticks or another form of adhesive to secure the components, cable ties for the large components, a soldering iron (with solder) and a pair of side cutters to snip off the excess lead wires.

  • Q: What type of solder is recommended for use with these boards?

A: Any general flux core electronics solder will work perfectly well, but solder that makes use of a no clean flux may be preferred.

  • Q: Where is the best place to install the crossover in the speaker enclosure?

A: Anywhere you can reasonably access without it interfering with the installation of the loudspeaker drivers. For smaller speakers it may be easiest to install the crossover with wires attached on an enclosure panel before final glue-up.

  • Q: Do you sell finished crossovers that have already been assembled?

A: While I do not normally keep a stock of assembled crossovers I can assemble any of these crossovers upon request. See this page for details.
