I understand the above needs a nice coat of veneer. Let get past that and examine the shape. There are multiple benefits to a curved speaker cabinet. Curves reduce the visual impact of an object. Take a look at your laptop, and notice the sides are curved. It makes what would be an oversized object, look a little thinner. The same is applicable here. In a speaker, that shape further prevents internal resonance, improving acoustic fidelity.
Now, more importantly than the pure aesthetics of the shape, for our purposes, is making the shape.
First is a guide to be used hereafter. All of the edges must be the same. Roughly cut a piece of MDF with a Jigsaw, then threw a piece of hardboard on there to smooth it out.
Used a router with and edge trim bit and the guide to cut the top and bottom of the speaker. They are now nice and equal.
Clamped the majority of the box together. Notice the backplate has been cut on the saw to the same angle as the back edge of the top and bottom. Gives a nice continuous edge.
Now this, utilized hardboard. 4 layers on each side. Copious amounts of glue between each layer. Used a trim router bit to get everything flush after days upon days of waiting for glue to dry.
There’s the end result. Had to throw some filler in a few of the mistakes that occurred. They’ll be veneered over, when I get to it.
Getting a little elaborate in rounding over the front edge. There wasn’t another way to ensure stability of the cut.
End result. Shows how effective the rounding can be in reducing visual impact. The speaker is a Statement II, the design can be found over at SpeakerDesignWorks.com.
