If there were ever a pair of speakers that could take a beating, it would have to be the Yamaha PDX-11.
Most speakers on the market have quirky, modern designs that are friendly for the home; the Yamaha PDX-11 doesn't look mean, but it does have that rugged look that kind of ups itself in the badass department. Instead of the conventional four-sided shape, the speakers take on an octagonal form that lends to a full, hardy look. Despite its bulky aesthetic, the PDX-11 is fairly compact and the handle on top makes it travel-friendly. Specs-wise, this packs a two-way speaker system and a large 4" woofer that provides heavy bass and a decent midrange as well as a tweeter for high frequencies.
The Yamaha PDX-11 is compatible with iPods and iPhones.
