Metal disc tweeter, agenda 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.

3rd Demo - Dual W8Q-1071F Tapped Horn

One more excursion video of the dual Tang Band 8x12" 16Hz tapped horn. After discovering a loose screw on one of the drivers in the last video, I decided to re-test using Flight of the Phoenix at reference levels to see what changed now that the air leak at the front driver is gone. This is the result. Power provided by a bridged QSC RMX-1850HD (about 1100W), highpassed at 10Hz. Note that the SPL meter is set on its highest setting, recording peaks in excess of 126dB. This amounts to about 122dB peaks at my listening position. The distortion you hear is massive amounts of low frequency energy overwhelming the camera's microphone. This thing was literally vibrating the concrete floor around the horn mouth.
