If you want a box with two tweeters and a woofer for some really legit sound, here's a design from a superstar of the DIY speaker design world:

He mostly just lays out the speaker and crossover design; but as he mentions a search for "TPA3116 2.1 amp" will give you lots of results on Amazon, AliExpress, and Parts Express.

PE's forums are good, lots of people have tackled similar projects:

For anybody else interested in this hobby, there are lots of fantastic kits out there, primarily for bookshelf/tower speakers and subwoofers.

The product page for the C-Notes (a fantastic value at $100/pair!) kit has a build video which gives you a great idea of the process and the tools you'll need. Process is similar for any flat-pack kit.

Of course you can also go as far down the DIY hole as you like, designing your own electronics and selecting drivers, etc.

I would love a C-note or the Overnight Sensations. Unfortunately UK shipping is a bit pricey! $90...
The C-Notes are still a bargain at that price!

There's about $80 worth of drivers in there, which is bonkers for a $100 kit that also includes crossover parts and MDF cabinets.

For comparison, the $130 Overnight Sensations kit contains about $55 worth of drivers. That's a good deal, and consistent with other DIY kits... and it illustrates what an outlier the C-Notes are.

(The reason why the C-Notes are so affordable is because Parts Express and Dayton share corporate ownership, so presumably they're about to source those Dayton drivers for next to nothing)

FYI there's an MTM (two woofers, one tweeter) version of the C-Notes coming in ~45 days for $100/speaker ($200/pair)

I need to hunt around for a cheaper shipping forwarder I think...
