Metronome build question???
Default Metronome build question???

I am going to build a pair of Metronome cabinets for a friend. He'll be using the Audio Nirvana 10" driver. At what angle do I need to cut the sides of the top and bottom pieces, as well as the bottom of the cabinet (edge of the MDF) that sets on the ground?
Thanks,
Mike

I would cut at an angle 45.

I used my router table to rabbet the edges of all the panels, with the rabbet on the front panels fractionally wider than deep. After assembly (alignment helped by the rabbet) I then used a flush trim bit to clean up the edges.

Rabbet - Wikipedia

As far as the top and bottom pieces, don't sweat the math. Just use the cut out front and side panels to set the angle for the table saw.

For the base sitting on the ground, I tacked on a straight piece front and back to act as a guide, and then used a hand saw to cut off the bottom of the panels. This not only gave me the proper angle for the flat base, but also fixed any minor mis-alignments of the panels.

Mike,

I have built quite a few Mets. The top & bottom pieces I get by measuring the angles on a scaled drawing. Cut them on a table saw set to the measured angles, but make them slightly over sized. I measure the size after the sides are glued to the baffle. Then I try fitting the top & bottom pieces to judge how much they need to be cut down to make a perfect fit, and to check the angles. Back to the table saw & trim them--slowly & carefully. I put a straight edge (thick metal ruler) across the side edges to see if the part is too wide for the back to fit properly. Any small amount too large I take off with a sanding block. I wish I had pictures to show, as it's easier to see how it works than to use words!

Oh, and remember to cut the hole for the port tube BEFORE you glue the bottom in!
