Editorial interest 78/100 Selection signal · not a rating of the site

A woodworking project pairs detailed Baltic-birch speaker-cabinet builds with a calculator that adjusts the dimensions and cut geometry to measured plywood thickness.

Landing page captured for the 2026-09-26 issue.
For
Shaper Origin users building plywood speaker cabinets
Worth noticing
One listed design is a mirrored pair nested from two sheets; the SEAS build specifies 20.5 / 15.5 mm Baltic birch.

Field notes

The page exposes two cabinet designs with dimensions, tuning frequency, and material thickness, then links those builds to Origin cut files and a thickness-adjusting calculator. Its notes distinguish nominal geometry from the machine’s kerf compensation and warn that one build’s joinery still needs confirmation. The project says speakers are first and that other Shaper-and-sheet-goods builds may follow; those additions are presented as future work, not existing catalog entries.
