Don here. Just joined after seeing a boombox I built show up on a thread here. Been building audio equipment for 40 years.
Welcome to the forum Don! Which boombox was posted on here? Those look like extremely well made units, you must have a decent tool collection and access to vintage parts? I couldn't afford a nice boombox when I was a kid so I built my own with cast-of car stereo parts, they actually sounded pretty good. One of my first jobs was a delivery driver and the van only had AM radio so I'd bring the homemade boomber along. I used to love cranking cassettes along the way.
You posted my first version of the 2nd one I posted above. It used ADS L200 for the main speakers and the Tang Band woofer is ported instead of the passive in this version. Here’s a picture of it.
I basically took the Parts Express kits and modified them to fit the look I wanted and used good mini speakers like the Boston or ADS for nostalgia more than anything but the also sound great.
