The cabinet uses HessBH Plan 2–3: 546 mm wide, 1,200 mm tall, 950 mm deep, 510 mm internal width and 18 mm panels. Fold locations, driver orientation and bracing follow the plan sections.
The LF18N405 uses the supplied RCF envelope: Ø465 mm frame, Ø425 mm baffle opening and 208 mm overall depth. Basket ribs, motor fins, terminals, wire routing, fasteners and surface microstructure are illustrative reconstructions, not manufacturing CAD. Small joinery details and brace contours are interpreted from the drawing.
Lining materials and their placement are exploratory visual options. They do not predict absorption, tuning, output or safe operating settings. The FreeCAD/Hornresp variant is supplied as a reference and is not blended with the dimensions of this plan.
Photo details now include four removable rear casters, fourteen hatch bolts, a wired dual connector and two notched mouth guides. Hardware sizes and recess depths are photographic interpretations. The Meten tab measures model distances between surfaces or projects driver points onto the inner hatch plane; these are not verified physical clearances.
The Warmte tab reproduces the PDF's hypothetical single-node thermal scenarios. It does not predict actual coil, motor or chamber temperatures. Cooling concepts and schematic airflow are separate visual studies; selecting a physical concept does not assign an unmeasured cooling benefit.
Controls: click a panel to select; double-click to focus. Remove or restore individual parts in Assembly. Escape clears the selection. R fits the view. F focuses the selected part. All assets are local; no internet connection is required.
