I Built a Boombox

Hi all. Just wanted to share my latest build. I'm pretty happy with how it turned out. I went with this TA2024 amp and this BT receiver. The speakers are pulled from a Logitech Pure Fi. I might upgrade the woofers but it sounds great already.

Someone at Home Depot messed up and I got some half inch solid oak planks for $0.01 each. No stain, just 2 coats of poly and a lot of sanding. The handle is a cabinet pull handle. I run it off of 3 18650s (lithium ion cells) in series (11.1v). The grille is something a roofer friend of mine gave me. I think its an overhead HVAC vent or something.

Nice build, what are model/vendor are these blue buttons?

Thanks! The buttons came from a kit like this. I originally tried to use the actual tactile switches by running jumpers to the signal wires and using a common ground but I could not for the life of me figure out what the problem was. So I redesigned the top plate and used just the plastic buttons over top of the button panel that came with the BT receiver. It was really frustrating.

You will notice that the plate before assembly is grey. That was the original one. Once I redesigned, I painted the replacement one black.
 
Very nice build.

Just a couple of tips for the future, line the insides of the speaker compartment with 20mm of open cell foam, it's purpose is to deaden the sound so it doesn't bounce off the back and sides and comes back out through the cone, and solid wood looks great but in all likely hood will come apart in time especially using just PVA (I only use polyurethane glue now).

Thanks, I did stuff it pretty densely with some pillow stuffing. The sound it tight but a little flat. I may upgrade the woofers to some Dayton ND65s to give me more of a low end response and I can try your suggestion then. I went pretty heavy with the wood glue so it might be a while before it begins to warp if it does.
 
yeah stuffing is a tricky thing because it is so widely misunderstood, in short it is only useful for speakers that are placed in boxes that are too small, and stuffing can tame a peaky response, but hardly the case for your 3" woofer, in fact it is what is making your speaker sound flat. It will sound better if you take the stuffing out even without lining the walls.
That Dayton fullrange is likely to be excellent but don't discount the logitech driver, they are a big company with a fantastic engineering department, the quality of drivers they produce for the prices is pretty amazing.
 
Agreed on the quality of Logitech speakers. I look for Logitech stuff specifically when I'm trolling my local Goodwill store. (The little drivers from their old MM50 are straight up amazing as far as sensitivity.) I Just tried to match the stuffing density of their original enclosure. I'm pretty sure my enclosure has at least 20% more volume than the original. I will try and pull the stuffing out and tune it a little.
