Dayton Audio MKBoom Portable Bluetooth Speaker -- A speaker that I put together from the Parts Express DIY Kit, this speaker has lots of power in a light package.
Works great and more powerful than most other portable Bluetooth speakers, this one also has line-in if you don't want to use Bluetooth.
Some things to note are that I did not finish gluing on the top piece -- I left it detached in case I needed to go in and change anything later on. Also, the wood is unfinished, as in, I did not put any paint or veneer onto it to make it look nicer aesthetically. There's some smudges of wood glue on it to be aware of that, with a paint, sand, and/or veneer, will not be a problem; plus, the larger of the smudges is on the bottom of the speaker, out of view.
