DIY

Got sent here from r/budgetaudiophiles after looking to replace my Klipsh bookshelf speakers. I love music but know very little about good speakers currently. Im looking for sources that have all the parts i need for a good bookshelf build and possibly a sub. Basically a kit or something to help me decide on parts. I am an engineer in the electrical field (granted i work on data centers) so I’m not a total noob with electronics.

Also does the enclosure material make a big difference? I see a lot of mdf and wood that look like .5-.75” thick. I have a laser cutter that can cut up to .25” wood that i would love to use if the material thickness is less important.
