Everyone should build a speaker cabinet at least once in their life, if only so they can realize how much thought goes into building a simple box. [John] of ibuildit.ca wanted a sound bar for his home theater setup, and that means building a sound bar. The result is beautiful, and a demonstration of how much you can do with just a router and a table saw.
[John] built this sound bar almost entirely out of MDF, which isn’t the best material but it works well enough for a speaker cab that’s meant to be mounted to a wall. The sides were constructed first, with a rabbet holding the front and back on. Both the woofer and tweeter are inset into the front, and a standard piece of plumbing pipe serves as the bass port. Slap a round over bit into the router and do some light sanding, and everything looks great with a coat of black paint.
As with any speaker enclosure, the design is effectively parametric, designed entirely around the drivers being used. In this case, [John] is using a spreadsheet named ‘Unibox’ that gives you all the formulas and graphs for designing a speaker enclosure.
With the box built and the speakers installed, the only matter left were a few aesthetic choices. [John] went with a standard black finish with a very nice wooden grille held onto the front with magnets. It’s a design that pops, but the true test of a speaker is how it sounds. That’s a bit hard to convey over the Internet, but [John] included a few sound samples at the end of the build video, available below.
