Lasonic
Lasonic produced some of the most popular boomboxes amongst collectors. Most of them were manufactured in Taiwan by Yung Fu Technology Electrical Corporation. During the late 70s and early 80s, they made silver colored models with fairly good build quality. But later, during the mid 80s, they started selling larger, black models with more fragile construction. I am referring to the TRC-931, 935, 951, and 975. These earned the nickname "big empty black boxes", which refers to a cavernous shell with little internal electronics to justify the large shell. Care should be taken when shipping these Lasonics, because the transformer might break loose from its thin internal mounts, causing it to act like a wrecking ball. However their attractive colorful graphics, large size, strong bass, and flashy looks nevertheless caused these models to remain popular amongst both collectors and casual consumers alike.
Lasonic revived themselves in the late 2000s by introducing the i931 model, with either Bluetooth or an iPod dock. These models, while retaining much of the classic look, no longer have analog dial tuners, even though the graphics might lead one to believe they do. This is understandable, because the graphics on the front look like a classic tuner window.
The Lasonic model list is shown below. Some were sold under the Lucky brand, because Yung Fu in English means Lucky.
