Is this the 'holy grail' of classic boomboxes? Maybe. Is the Sharp GF-777 a must-have for boombox collectors? Probably. Fact is, it's huge (just look at the pic below). It looks retro awesome and it's pretty LOUD. Oh, and it has a double cassette deck. And 6(!) speakers. This 'portable' (almost 12 kg) multi-amp baby with super woofer will EAT batteries, that's for sure. But is it worth it? Introduced in 1981, this ghetto blaster has a sound quality which is perfectly balanced by Sharp engineers, meaning clear and superior sound. Hey, this box looks so cool, what else can you expect?

All 4 woofers are 16cm (6.5") each and the outer ones are full-range speakers. These deliver a full range of sound and are 4 ohms. The inner ones are tuned only for mid-bass and bass and are 4 ohms. The two tweeters are located above the outer woofers.
