The stereo unit is built around a two-way system featuring a soft dome tweeter and a powerful compact woofer loaded by a passive radiator, for each channel.
The dock is suggested to include an FM transmitter for piping navigation audio throughout your vehicle's sound system, as well as allowing external DAPs to be heard through more than just a built-in tweeter, but we're still waiting to see if TomTom plans on this being a standalone unit or if it fits better integrated into one's dash.
