Welcome to the group. Yes, if you have the tools and knowledge, you can build great speakers for less.
If you want to build some amplifier, we have various pcb and parts here in croatia, like TDA7293 original chips, you can find it on "njuškalo" in Rijeka.
I assemble so many of these amplifiers myself so we sell it like sort of kit because I already buy all parts in large quantity.
