This Hitachi TRK-9100 isn't a big boombox nor is it an iconic collector's box. But, it's a good little entry level boombox with plenty of features. Probably its main feature is that it has two detachable speakers so it's actually a three piece box. There are small compartments on the back of each speaker that hold the speaker connector cables.
The Hitachi TRK-9100 was made in 1983 here with the W designation and in Europe with the E designation. It's a pretty loud box for its size though some claim it lacks in the bass department. As you can see it's a single cassette box with a 3 band graphic equalizer, loudness and tape functions and four radio bands.
These small Hitachi's aren't all that popular with collectors and you can find pretty nice examples of them for around $50.00.

Now this is a different looking boombox. Of course Bang & Olufsen has always been into futuristic looking designs and the Bang & Olufsen Beosystem 10 definitely fits that description. It's black and gray color scheme and super sleek and thin look make it appear as though it was produced this year as opposed to 30 years ago. In fact, the Beosystem 10 was made from 1985-1991. It was a fairly popular boombox but did have some deficiencies. First, it had no Dolby noise reduction. Second, it did not have an auto reverse cassette mechanism. Third, it only had one tone control. Most boxes of the time had separate bass and treble controls.
I believe Beosystem 10 was made by a Japanese with only a moderate amount of Bang & Olufsen input. It featured AM/LW and FM bands and three preset FM stations.

The Beosystem 10 was discontinued in the early 90's and there was no replacement boombox made by B&O for sometime thereafter. While it does have its deficiences in terms of performance it's still fairly popular with collectors today. A Beosystem 10 in good working condition can sell from $100-$300.
