About Subwoofer Plans

Subwoofer Plans makes it easy to build a great-sounding subwoofer. For each driver we engineer a sealed enclosure to a precise acoustic alignment, then deliver everything you need to cut it: whole-millimetre DXF cut files, full-size 1:1 print-and-tape templates, STEP and STL 3D models, a complete cut list and a predicted response curve.

Every plan is designed around real, off-the-shelf hardware, with round drilled brace holes at standard hole-saw sizes so you can build it with a drill — or feed the DXF straight to a CNC. No guesswork, no fudged dimensions.

Plans are sold as instant digital downloads through Gumroad. This site is where you find the right plan for your driver; checkout happens securely on Gumroad.
