18" DIY Subwoofer

Something Wicked this way comes!

18" Dayton Audio RSS460HO-4 subwoofer

Sealed 110 liter Plywood/MDF/HDF enclosure with intricate internal bracing

Airtight Speakon connector, 1" Industrial rubber feet.

Painted with Rustoleum Hammertone "Black"




Internal braces

Braces dry-fit, this is the back of the subwoofer

Detail of internal bracing system. It's a tight fit.

Gluing it up with corner clamps and bar clamps

The box is made of 3/4" plywood and some 3/4" MDF


All seams were screwed and glued. Uneccesary.

Added more braces to my braces

These corner braces were meticulously cut to fit tightly

Looking through the front hole. This is one baffle, the next is comign soon.

Adding the second baffle, using all my clamps

A little bit of squeeze-out

A little gap there, but it's clean.


The woofer sits just slightly proud
DIY family: 12" Raven subwoofer, 18" Wicked subwoofer, and curved Mandolin speakers
Added hardboard to the top and sides, and then flush-trimmed the front. This actually wored really well.

The hardboard made it thicker, smoother, and covered up the screw holes

The back was also skinned with 1/8" hardboard

woofer cutout with all internal bracking visible. This is a stiff cabinet


I added about 4 layers of grey spray primer, and now Rustoleum Hammertone is going on



I probably could have masked off the inside, but I didn't really care about some overspray

Airtight speakon connector with rubber gasket

Added some R-13 fiberglass insulation. Actually this is overstuff and I need to remove most of this.

One subwoofer is a little proud, the other is recessed
