From the European company "Karcher" comes this RR-512, another imitation of the classic JVC Kaboom. From photographs it makes a good initial impression. It is rare to see a ghettoblaster manufactured in the year 2015 with a cassette deck, let alone TWO of them. It also has a CD player, a 4-band radio tuner, Aux In, and a USB port. It measures 66cm long, and takes eight D-cell batteries.
The owners manual says there are 4 speakers: 2 tweeters on top, and 2 bigger speakers in front. The owner's manual does not mention any speakers on the left and right sides of the cylinder. However there are "openings" on the left and right sides of the cylinder, styled to look like speakers. This means that either they're fake (sealed off), or they are passive membranes, or perhaps foam-covered ports/vents. Whatever the case, user reviews on Amazon report that its sound quality does not meet expectations. Specifically, lack of bass.
Users also report poor build quality. It weighs only 5.7kg, less than a good midsize boombox from the 1980's. Users complain of loud mechanical noises from the tape decks, buzzing noises from the CD player, and random delays between functions. What's hilarious is that according to the owner's manual, the tape deck's "wow and flutter" is 0.35% WRMS, which is absolutely horrible. More proof that today's consumer is clueless and does not care about quality, only price.
