LSP Documentation Page – drawings, photos, specs and more

Members of the LAB community began the LAB Subwoofer Project years ago, and many members have contributed drawings, specs, photos, and experiences in designing and building a LAB subwoofer. We have a forum dedicated to the LAB Subwoofer and all the LSP Documentation right here.

DXF drawings for 18mm wood

Eric Hendricks has converted Jeremy’s .dwg files (see below) to .dxf format. Thanks, Eric!

Jeremy Bridge has converted the drawings for use with 18mm wood, which is the most common material. Thanks, Jeremy!

Jeremy’s DXF drawings for use with 18mm wood now available as PDFs (Adobe Acrobat), thanks to Raj from Canada.

By the way, Jeremy notes that “these plans are MUCH easier to build completely in metric. The imperial measurements are ugly.”

Fabrication Photos

AJ Cooper kindly submitted these photos of the Lab Sub in the process of assembly.  THANKS AJ!!
