The electronics come from an Overnight Sensations speaker kit, and its panels are the dimensional template for the whole build. Nobody will ask you about them. They will ask about the walnut.
The plan builds a pair of speaker enclosures: walnut strips glued into panels, grooves for the internal panels, a removable bottom on six screws, and an oil finish. The wiring follows the kit's crossover diagram, soldered and insulated.
What makes this box different from a bookcase: it has to be airtight, not just square. The plan treats grooves and sealing as the real work and closes with a leak test before the drivers go in for good.

Before you cut the grooves:
A gap a bookcase would forgive turns into a rattle or an air leak you can hear. Cut the grooves snug, seal the seams, and run the leak test before the drivers go in for good. Tight first, pretty second.
Every step that makes these boxes work — snug grooves, clean glue-up, sealing, a finish that earns the shelf spot — is general shop skill, not speaker knowledge.
One plan gets this pair built. The next project that asks for the same tight grooves and clean glue-up is already drawn, cut list included.
What one of the plans looks like
One plan, front to back
Every plan in the library comes with the same three things: a cut list you can total before the lumber run, measurements on every part so nothing gets scaled off a photo, and step-by-step instructions from rough stock to finish. That is the layer this speaker plan gave you, sixteen thousand more times.
The library covers furniture, shop jigs, outdoor builds and small projects, beginner to advanced. It works with a few hand tools or a full shop, and you keep it for good.

Woodworking Secrets is a printed book on layout, cutting, joinery and finishing, the part a plan leaves out. The publisher sends it at no charge and you cover the shipping. It ships to US addresses. On the order page there is a box for a trial membership that is already ticked — untick it if you only want the book.
