Panasonic RX-5090
The RX-5090 (nicknamed "Silver Special") was a mid-level boombox from Panasonic. It was recently featured in the "Stranger Things" TV series by Netflix. It was made in the early 1980s, and it must have been one of their more popular models, because even today you can find a few of them on Ebay every single week. It has 4 speakers (12cm woofers and 3cm tweeters), output power of 2 x 2.7 watts, and Line In ports on the side that you could connect your phone or iPod to.
