Not your ordinary set of bookshelf speakers, Audioengine’s A5s bring a whole new set of options and versatility to the genre. A quick look to the back of the cabinets will be your first clue with ports for a subwoofer and aux power being the most obvious. Drop a pair of these in your library, add an Airport Express (juiced from the aux port) and you’re streaming music. Reviews are thumbs up with many claiming the speakers to be of audiophile quality. Other niceties include 2 audio inputs, built-in power amplifier, front panel volume control, Kevlar woofers, Silk dome tweeters, and magnetic shielding to protect your other electronics.
