Purchasing Notice: These are heavy flat packs that get shipped in two boxes.
8 years ago in 2014 I designed this slot ported Cube-15 and sold them for $165 each. Demand and reviews were great, but packaging by myself was very time consuming. So for a while they were only available in bulk pallet orders of 30 units. Now with more helping hands I've decided to bring them back in their original form. We all know wood prices have been up and down recently, so I ordered a large number of these at the same time. The larger quantity kept the price under control and almost the same as they were 8 years ago!
The Cube-15 is a 4 cubic foot (net volume) subwoofer flat pack made from premium 3/4" MDF. The cabinet is tuned to 21hz using a large slot port that extends along the bottom and up the back panel. It was originally designed to perform great with the 15" Dayton Audio RSS390, Eminence Lab-15 and the 15" Stereo Integrity subwoofers. But over the past 8 years people have used the Cube-15 with many other high powered subwoofers.
When building any subwoofer cabinet it's very important to know the net internal volume of the cabinet, not just the outer dimensions which is only the 'gross' volume. 'NET' is the true internal box volume after subtracting off bracing and ports. If you don't know the net volume of your cabinet it would be hard to decide if it's right for your particular woofer.
Product Highlights:
Every panel is precisely cut using a $400k industrial CNC router so panels fit together perfectly in rabbet joints and dado grooves. There's no overly sloppy assembly with our cabinets and they can be assembled easily without screws or nails. In fact, cuts are so precise that some people have assembled them using nothing but strong masking tape to hold the panels together while the glue dries. Well thought out and tested designs, incredibly accurate cuts, and premium quality wood are what make Denovo flat packs so popular.
Note: I did not have the CNC company cut holes for terminals because everyone likes using something different. Terminals or binding posts can be shipped for free if you order them at the same time you order this flat pack.
6 years of having two Cube15s and they have put myself, family, and friends through many great movies. The precision CNC cuts made assembly a breeze and they are sturdy enough to use as a seat is you really wanted to. The cube shape makes them easy to fit in the proper spots for room response too.
I paired mine with the Dayton 15" HO which matches very well with these cabinets.

Assembly Notes:
This is an easy cabinet to assemble and can be done a few different ways. Believe it or not the panels go together so good that some people have assembled these just using masking tape to hold the pieces together. That's actually what they do in cabinet shops. My directions make assembly sound a bit harder than it actually is, but once you have the panels laid out, you'll see how easy it can be done. My directions assume you're using a wood glue like TiteBond, Elmers wood glue, or something similar.
Assembly Tip: When clamping, you don't need to put lots of pressure on the panels, just enough to keep them from sliding around. Too much clamping pressure just squeezes all your glue out which isn't really a good thing.
Assembly Tip: Dry fit panels as you go and mark where you need to put glue so that glue is used anywhere two pieces of wood touch. Take your time.
Assembly Tip: Rabbet joints are purposely cut about 1/64" bigger to allow for user error, slight shifting, excess wood glue, etc. while gluing them up.
Assembly Tip: Sit the bottom panel up on something to keep it a few inches off your work bench. This allows the head of your clamps to fit under the panel so you can clamp the other pieces to it much easier.
I prefer to glue the port pieces together in first. Then bracing. Photos coming.
Last piece is the outer baffle. Just put a bead of glue around the edges, then around the woofer cutout, then just drizzle it around the rest of the areas. Lay the baffle on. It will slide around a little bit, but don't worry. Lightly tighten your clamps down while working your way around the box shifting the baffle into position. If you have a small clamp, you can use it inside the woofer cutout to clamp the inner baffle to the outer baffle.
