Magnavox D8265
Most Magnavox boomboxes were actually built by Philips, and Philips was known for producing very funky designs. Like this D8625 (also called the Cubic Compo). It's a 3-piece boombox with triangular detachable speakers. Unfortunately it really doesn't have any features besides a tape deck, an AM/FM tuner, and a 3-band graphic equalizer. Still, it's definitely a unique and interesting design.
