The electronics in this build come as a ready-to-assemble kit for around $30. 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 is assemble-by-numbers with polarity marked.
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. A broader reference helps when the next project asks for a different joint, surface, or setup.
