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.

Does it go loud this amp, not loud and lots of bass and treble, not high quality, but even high volume would be fine.

@Vintagesoundz14 No.

[Vintagesoundz14]

what is the model of this amp i could do with one of these for the garage i dont want a high end expensive amplifier in the garage only to get dusty and used occasionally one of these would fit nicely on the shelf.

@Vintagesoundz14 The model is written in the video title!

One thing to consider: The disc tweeters may be blown. Without caps they would see the bass and there's no way they could handle that.

@transdrole No, they're just a gimmick, designed to fit the technical description of a "tweeter" without actually doing anything useful.

A tweeter will make sounds that you wouldn't notice by just looking at the speakers. Tweeters are a way to compliment a subwoofer mainly, when a beat is too low and there are highs within it those tweeters are what play that high, however in this video it's probably played outside it's original load correct?

@ThisIs2009 that metal disc is the exact same thing that is in the average smoke alarm.....

[Vintagesoundz14]

it sounds loud on the video: "Realistic SA-10 amp + Denon TU-680NAB tuner + Dynaco 208 speakers" well i still would like to get myself one of these.

You got a like because of your cat

The Wonderswan series of handhelds used these disc speakers and actually were able to get some reasonable sound from them
