3D Printed Subwoofer Plans

Add dedicated low bass to your desktop or small-room system with a 3D printed subwoofer. Subsonic Mk3 is a passive 6.5-inch design that needs an external subwoofer amplifier or a suitable amplified 2.1 subwoofer output. Subsonic Mk2 uses a built-in 2.1 plate amplifier and dual 4-inch drivers.

These are digital self-source plans, not finished subwoofers or components kits. Check the sourcing guide, printer volume and amplifier arrangement before buying. Your main speakers are purchased or built separately.
