Excerpt: Audioengine is perhaps best known for its critically acclaimed, self-powered, desktop monitors, such as the mid-sized model A5 ($349/pair) and the smaller but—in its way—no less impressive model A2 ($199/pair). But the firm’s newest speaker, the P4 bookshelf speaker ($249-$325/pair, depending on finish) is a passive design. Why would a company that evidently specializes in self-powered speakers choose to add a passive model to its lineup?
Excerpt: We've listened to and enjoyed a couple of powered Audioengine speaker ranges in the past, but this is our first encounter with any of the company's passive designs. The AP4s are extremely compact (less than 23cm high), front-ported two-way speakers – the tweeter is a 20mm silk-dome affair, with a 100mm Kevlar driver below. Our review pair is finished in satin black, but glossy white and something called ‘solid carbonised bamboo' are available too.
Pros: Usefully small, exemplary finish at the money, sweetly articulate midrange, good integration
Cons: Fractionally bright at the top end, slightly inflexible at the bottom
