XtremeMac has made an wireless speaker system tailored expressly for the iPad, iPod touch and iPhone. The Tango TRX is a 2.1-channel speaker dock but uses a universal iOS app (free, App Store) to send audio wirelessly over Bluetooth. Its design both mimics the physical remote’s controls and has an EQ to adjust the tone of the sound to a particular style.
The Tango TRX includes a dock to take audio directly from a given player; a special Apple Store version, the TRX D, has a separate charging dock that can power the source device while it streams music. A 3.5 mm line-in jack provides a way to supply audio from non-iPods sources.
Either Tango TRX variant will be available later today. The core version will cost $180, and the Apple-exclusive version’s dock raises the price to $200.
