Robo Cabinet

Kreg's pocket hole jig sure makes building speaker cabinets more fun.

This is my first project using BB and a cabinet builder let me borrow his kit.

I'll never go back to MDF.

it looks great. what drivers are you going to use?

[---k---]

Yeah. You'll notice some pocket holes in my photos. Unfortunately, I ended up abandoning some of it because I couldn't get the drill in like I thought I would. The box was just too small. I could have made it work, but it wasn't needed so I moved on.

That looks really cool! I'm planning a similar shaped box, but with a sloped baffle (kinda hard to tell if you did this or not). Which Kreg kit did you use, as there are so many of them? Also, how does the mass of BB compare to MDF? Finally, is that the entirety of bracing that you will be using for the cabinet?

The Kreg tool I borrowed is one of the fancy things. It worked so good that after installing a couple of braces I went to Lowe’s and bought the cheapest ‘Mini Jig’ and used it for the rest.

As –K—pointed out, access can be a problem when using a drill to drive the screws, which are a #2 square bit. I made a shorty screw driver by using a 3” long bit, a small plastic cup and a few ounces of epoxy.

The big advantage of using screws is the flexibly they give you. If clamps don’t fit, it doesn’t matter. Even if clamps do work, you don’t need to wait for glue to dry to get the clamps out of the way.

That’s all the bracing I’m going to install. I don’t believe adding more will achieve anything positive and may actually make things worse by lowering resonant frequency by adding mass. I will be adding constrained layer damping to some of the larger open surfaces. My experience with CLD is limited to some garage experiments I’ve done so I’ll see how that goes.
