Speaking technically, let's start by looking at some specifications.
Output power: N/A
Speaker dimension: 3.35 inches (8.5 cm) by 7.77 inches (19.5 cm) by 3.54 inches (9 cm)
Cable length: 6 feet
Jack: stereo mini: Yes
Frequency response: N/A
Pick-up pattern: N/A
Weight: 0.8 pounds
Connectivity: 30pin Ipod/Iphone dock.
Unfortunately we have not been given a whole lot here from Logitech in terms of system specs to go by. However, I can add that the speaker drivers are approx 2" and the frequency response would be around 600Hz through to 16KHz, just as a guess based on systems I've tested before.
Also included is a second connection option in the form of an Aux input in the rear, which would allow for just about any portable device to be connected to the unit failing the use of an iPod.
There is also a 'bass boost' button available which allows the user to add an artificial EQ tweak in order to boost bass to around the 500-1KHz range.
There is no remote control included, but one can be sourced out from Apple if the user is so inclined. Higher end models from Logitech also include remotes.
The unit is built from rather high quality molded plastic and should provide some protection against internal rattle caused by bass as well as accidental bumps and drops.
