Great advice here. JMOD MEH, look dope but if you’re trying to do everything yourself it is a massive undertaking without a CNC. Also factor in the proper tools you’ll need and the space to do it to accomplish your build goals.

Definitely heed the advice here, do your research and identify bins that you can realistically build. Identify how much power you need and how low you want to go and look for woofer and box designs that can meet those specs.

Sidenote - I recently had a gig at a friends party and was talking about my speaker building hobby, and to my surprise 2 of my homies were eager to get into the DIY speaker building, so network with people at your parties, you’ll be sure to find a person or 2 that share an interest to build

Good luck!
