Introduction: Mount a Speaker Under a Cabinet

I have a Sonos wireless speaker system that I love! In the kitchen we have one Play:3 speaker that has sat on the counter taking up valuable counterspace, and leaving the power cord visible. I wanted to mount it to the cabinets above the counter. I did a little research and found a number of expensive brackets that would also take a fair bit of work to install. Then I stumbled upon this thread on the songs forum that gave me the idea for a simple, super cheap way to get exactly what I wanted.

Many thanks to the folks on this thread for saving me some money: http://forums.sonos.com/showthread.php?t=30332

I've adapted their method and shared it here. The whole project just a couple of dollars and I had much of the materials lying around.

Materials:

  • 1- 1/4-20 Bolt 1 1/2" long
  • 2 - 1/4" nuts
  • 2 - 1/4" locking washers
  • 1 - Corner brace 5"
  • 1 - piece of scrap 1x4 about 8" long
  • Wood glue

Tools

  • Saw
  • Cresent Wrench
  • Drill & Driver

Step 1: Prep a Spot to Mount the Speaker

The underside of my cabinet had some 1/4" veneered MDF which I didn't think would be strong enough to mount this safely into. I also wanted the screws I used to mount the bracket not to protrude into the cabinet. So I used a piece of scrap 1"x4"x12" lumber, applied wood-glue and then screwed it into the cabinet.

If I were to do this again I would have positioned this piece an inch or so further back into the corner. Its ok where it ended up, but might be nicer more recessed. I let this cure overnight before moving on to the next step.

Step 2: Customize Your Bracket

The holes in the 5" bracket would work , but I found there to be still too much space between the top of the speaker and the cabinet so I measured the distance I wanted and drilled a new hole in the corner brace.

Then I screwed the bracket to the piece of support wood in a location that would leave my speaker centered in the corner and angled to the center of the room. When I first mounted so that it faced straight out of the corner I found that from the rest of the kitchen I would see a lot of the side of the speaker and not the face. So I adjusted it to where I wanted it.

Once you screw the corner brace in that's the end of your adjustment so be thoughtful at this step.

Step 3: Assemble Your Pieces and Mount It

This is where I went with a "jam nut" approach instead of using a single wing nut. This is because I'm mounting this speaker horizontally and it will cantilevered all the time. I just don't want it to loosen up!

So assemble the hardware in the order shown while supporting the speaker under the counter. I had to lay on my back on the counter but another set of hands would be handy. Remember that for the play:3 you will flip the speaker over so it will have the volume and mute button on the side facing the counter. Tighten the bolt to a moderate tension, hand tighten the nuts down so they touch the split ring washer. Then with the credentials wrench tighten the nut closest to the speaker until the two locking washers are compressed. Then tighten the second nut to back-up the first.

I found that I could tell the tension was enough when I removed my support of the speaker and found it wouldn't turn down.

Step 4: Celebrate Clutter-free Peace

I have an electrical socket in the corner that I installed for the under cabinet lighting so I could plug the speaker in there and shove any loose cables into the space behind the cabinet.

Then I could stand back and revel in the satisfaction of a professional looking installation, that frees up valuable counter space for a fraction of the cost of a store bought mount.

Ahhhhh!

The installation has held strong with no issues for over a month now and we love it. Many thanks again to the others of the post on the sonos forum that saved me a chunk of change!

I've entered this into the "on a budget" contest. So if you liked this please vote for it!
