Everything about the Duo i-plus is serious. This is not just another wimpy iPod/iPhone speaker dock—in the categories of aesthetics, functionality, and power, it is meant to stand out. This dominating attitude turns out to be a mixed blessing, but under the right circumstances, the Duo i-plus is an audio standout among a sea of lesser competitors.

iPhone and iPod speakers come in many varieties. Some are about portability, some are about functionality, some are about style, and some are about sound. You want a system that can satisfy your needs in all four categories, but such systems are hard to find. So, you often have to make some sacrifices. Thankfully, those sacrifices are likely worth it with the Altec Lansing inMotion Compact speaker system.

Given its broad acceptance as an audio technology, it is only natural that Bluetooth is now cutting the cords between music players and speakers. The Tenqa SP-109 is an excellent introduction to that market, handily allowing the separation of your music source (laptop/iPhone/other device) from the speakers on which you listen to it.
