Boston-based Tivoli Audio products are known for great sound, but they're also known for their eye-catching looks. Design-oriented speakers are nothing unusual, but Tivoli's vintage-style radios and speakers are particularly irresistible. If you have an Eames Hang-It-All or Emeco chairs, you kinda need a Tivoli Model One sitting on a shelf nearby. Last year, Tivoli attempted to translate its signature style to portable products with a new line called Tivoli Go.
