I finally got some 3/4″ MDF to build the box for the Lanzar MAX10Ds I got so this post will feature my design and a few build photos of the enclosure. It is 5.4cu/ft before woofer and port displacement, 4.4 cu/ft after. This gives each sub 1.1 cu/ft. The box is tuned to 33hz and features a rear mounted slot port, the woofers face up. The port size could be a bit larger but I figured it will do, it is 18.5″ x 2.5″ x 17.75″ long. This leaves about 5″ between the port and the front of the box.
SPL Science Slot Ported box for 4 x Lanzar MAX10D
Rough 3-d sketch of the box
Box layout from a single 4′ x 8′ sheet of 3/4″ MDF.
- 24″ x 24″ x 20″ tall
- 5.4 cu/ft prior to woofer/port displacement ; 4.4 cu/ft after
- 18.5″ x 2.5″ x 17.75″ long slot port (Rear facing)
- 4 x Lanzar MAX10D Subwoofers (Top mounted) Wired to 2 ohm final load (DVC woofers in wired series @ 8 ohms, then all paralleled together)
- 3/4″ MDF 8×4 sheet (didn’t use the entire thing)
- Elmers Max Wood Glue
- 2″ Screws (Lots)
- 1″ Screws to mount woofers. If I had a double top plate I’d use the 2″ but with only 3/4″ no sense using longer than 1″.
- Total Cost – $96 for 4 Woofers, $33 for the sheet of 3/4″ MDF, $8 worth of Screws, $6 Glue = $143 plus carpet and a terminal cup.
Drawing out the holes for the 10’s. Still just testing fit before mounting anything together.
Test fitting the wood before building.
Woofer holes cut, I currently don’t have a router so I had to do it the old fashioned way with a jigsaw.
Woofers test fit.
Getting some panels mounted.
Top view, port on the left.
All screwed and glued, just need to add the brace. (Had to do it old school, but I will get a nail gun for future builds. I forgot how much of a pain it is to do it this way.)
Brace mounted, you can see it in the center of the box. This will keep the top of the box from flexing.
That wraps it up for now. I have mounted the woofers and tried it out but until I can get a terminal cup and carpet it will look as it does above, except with woofers. Videos to come…
