The Audioengine 5 speakers measure 10 inches high by 7 inches wide by 7.9 inches deep. They each have a 5-inch Kevlar woofer and a 20mm silk dome tweeter. Because the left speaker houses the amplifier (50 watts per channel), it's heavier than the right speaker. Unlike the 2s, which are ported on the front, the 5s are ported on the rear.

It's worth noting that both the 2 and 5 series Audioengine speakers come nicely packaged, with cloth covers over the speakers and cables. The left and right speakers connect to each other with "real" speaker wire (included) and you also get an input cable that allows you to connect your PC to the 3.5mm aux input on the back of the left speaker. The use of standard cables means that--unlike some speakers with proprietary connections and cables--you can invest in custom-length cables that are as long or as short as you'd like.

What's most unique about the Audioengine 5 speakers is the 3.5mm aux input on top of the left speaker that sits next to a USB
