There are numerous designers that offer complete DIY kits for speakers they have designed. Other designers offer detailed plans and allow you to secure your own materials. If you are not purchasing a kit but will be building speakers based upon a set of plans and will need to select or purchase crossover components than the information you want is on the Schematic based builds page.

If you are still here, the following info and pricing applies to DIY kits purchased from a designer or retailer, or for any design you have already purchased the components for.


My assembly fee for kit-based crossovers begins at $75 for a pair. (A single center channel board would begin at lower price). Most bookshelf or other 2-way designs are priced in that lower range of $75 to $90 for a pair. Three-way designs or kits having 3 or more inductors may be slightly higher depending upon the design.

An increase in the assembly cost is necessitated by things such as a higher number of inductors, a design that requires circuits be separated onto more than one board per speaker, abnormally complex layouts due to sizing, or abnormally high number of components.

For a free price quote please contact me by email. I will send you an assembly price quote based upon the complexity and size of the crossover network.

What’s Included:

The assembly price includes the crossover boards that I will size to match your components as well as your cabinet opening and interior space. It also includes the small incidentals items such as zip-ties, solder, and heat-shrink tubing where it is needed.

The Process:

In general, for kit-based builds, or builds where you have already acquired the needed compenents, you will ship the crossover components directly to me at the address I will provide to you, or either of us can arrange to have the retailer drop-ship your purchased kit components directly to me to save you that additional shipping effort and expense.

I will email you when I receive your package so that you know your items have arrived and are secure.

As I near completion of your assemblies I will send you a paypal invoice for the assembly fee and return shipping. I will add shipment tracking info to your paypal recepit so that you can track the return shipping progress.

My rant about shipping insurance:

Note: If I estimate the value of your raw components to be greater than $300, I will automatically add the cost of shipping insurance at your expense (1.5% of insured value. $300 insured value = $4.50 cost). That is cheap protection against total loss. You will see that additional cost on your paypal invoice. If you prefer to not purchase shipping insurance I will remove it upon your request. If the value is estimated below $300 than I will add insurance only f you request it. My recommendation to you is to request shipping insurance, but it is your choice and responsibility. Shipping accicdents are fairly rare but they can happen. I can not assume responsibility for things outside of my control. If the delivery company delivers your package to wrong address, crashes the delivery van, loses your package, plays soccer with your package, or if a porch thief steals your package, those are things clearly out of my control that I can’t assume responsibility for. I can’t buy you new crossover components if any of those, or similar things happen, so please consider adding the insurance if you don’t want to assume that risk. Almost without exception I ship all packages either USPS or UPS. If there is a particular mail carrier that you want to avoid or prefer to use, please let me know.

Despite that disclaimer, I am a very reasonable and considerate person. It has not happened yet but if perhaps your item does receive some damage and needs repair, I will donate of my time and service to help correct the issue, but I am not able to pay for the repurchase of lost or destroyed items. If you live in an area where package theft occurs, than please request a signature requirement for your package. That signature requirement lets the driver hand it to a resident of your address instead of leaving it outside and unsecured.
