Hello internet I’m Leo and recently I have been enjoying building both headphones and speakers :)

I guess I’ll include some photos of finished projects and what I used. Feel free to ask any questions or make fun of me.

First larger speaker was built using an old speaker box I gutted out. Used a 12v battery and 24v step up converter to a bluetooth amp that supposedly puts out 100w per channel, all from aliexpress. I had a pair of 2 way alpine 6x9’s I removed from my car when I upgraded my sound system, I inserted them on a new baffle I cut out of plywood to fit the old speaker box. As you can probably guess it doesn’t sound great for a multitude of reasons but at the end of the day I’m happy it worked and is listenable to.

Next is a smaller speaker, again using a 12v battery and bluetooth amp putting out an advertised 50w per channel. This time I purchased a pair of dayton audio rs100-4’s and implemented the plans of a build I found here on diyaudio utilizing the 8ohm version of the rs100’s for a slotted vent box. The build went as smooth as the sound it produces, although it is missing some high end for my taste, maybe I go back and attempt to install tweeters?

The next one was sort of a joke, harbor freight ear muffs with cheap aliexpress drivers. Obviously sound really really good!

Last but not least headphones built with a pair of tymphany HPD-50N25PR00-32. Wood cups tuned to the best of my ability and again headband from aliexpress (surprisingly nice)
