Metal disc tweeter, cardboard box speaker, Realistic SA-10 amp
Many boomboxes and stereos in the '80s and '90s had little metal discs "tweeters," often with grilles shaped to make them look like horn tweeters, that were wired up but didn't seem to actually do anything. Here I solve the question of whether these "super tweeters" really make any sound or if they're just totally fake. I also demonstrate one of a pair of 12-inch vintage 1962 woofers that were rescued from a Lowrey Brentwood tube-type electronic organ that was being dismantled about 7 years ago. I've had them crudely bolted into a pair of cardboard boxes ever since, and now I'm thinking of finally giving them a proper home in some real speaker cabinets with good midranges and tweeters to match. Providing the sound for both is a 1986 Realistic SA-10 mini stereo amplifier. This was one of Radio Shack's longest-lived pieces of audio equipment, sold all the way from the 1970s up to 1994. With 1.2 watts per channel it won't rattle any window panes, but its simple 10-transistor design gives excellent unmolested clean sound.
