Stem Innovation (http://www.steminnovation.com/) has released the Tandem USB Digital Desktop Speakers for Macs and the TimeCommand audio alarm clock for the iPhone, iPod touch and ipad.

Tandem features proprietary Stem:Sonic iQ technology, a DSP-enhanced amplifier and performance tuned bass-reflex ports. The speaker system features a sleek enclosure, cloth grille and black acrylic top to perfectly complement any Mac, according to Gary Bart, founder of Stem Innovation. In addition to the USB digital pathway that delivers ideal audio throughput, additional audio sources may be connected using the auxiliary audio port on the back, he adds.

Tandem’s speakers enable the main unit to be placed on either the left or right of a Mac notebook or desktop by taking advantage of a simple left/right swap switch. There’s a headphone port on the main unit for personal listening.

Tandem is currently available through Apple retail and online stores for the holiday shopping season. The suggested retail price is US$99.95.

The TimeCommand audio alarm dock features an acoustic system with Digital Signal Processing and proprietary Stem:Sonic iQ technology, as well as the ability to control a connected bedside lamp with the touch of a button. The Stem:Connect App for iOS devices — a free download at the Apple App Store — adds a variety of user-customizable features, including a 10-band graphic equalizer, bass enhancer and free Internet radio playback. It also allows the user to control the dimming of the bedside lamp as well as automatically turning the lamp on or off upon waking or sleeping.
