The designers at Buro Vormkrijgers, a Dutch design studio, call it "functional kitsch", but you might think of it as a speaker that redefines the meaning of the word "woofer".
In fact, those crazy Dutchmen have punnishly (punishingly?) named this unusual speaker "Woofer". They describe it as a speaker that "holds the middle between your loyal four footed companion, and an addition to your surround sound system. By adding a function to an otherwise “grotesque” object, it acquires new aesthetic values, becoming an object of desire."
