Features and Design
The Luna looks somewhat like a miniaturized version of the XtremeMac Tango speaker system, sans the wide beveled top. The outer shell is made of glossy, smooth white plastic that is a near match to the material used to make the beloved 1-3G iPods of yore. The Luna is wrapped nearly 360 degrees by a shiny black mesh-like grill. Under the sleek black grille are two (roughly 2") speakers that put out 10 watts each, along with a two-channel amp. There are no separate tweeters or subwoofer.
The physical dimensions of the XtremeMax Luna are 11"x5.5"x2.9" and weighs in at a modest 3lbs 7oz. Add 2oz. for the included remote control.
XtremeMac includes nearly everything you'll need to instantly begin listening to music through the Luna. You get the Luna itself, the color-coordinated remote control, power plug, clunky AM antenna, FM antenna and a wee bit of documentation. There were no iPod dock adapters included with my Luna. This may have changed since the time mine was packaged and shipped, however it seemed to be a little bit of an oversight on XtremeMac's part to not include such an inexpensive but necessary part.
Remote Control
The Luna's remote control is set up much like the Tango remote, but has a few more buttons. It has power on/off, source (FM, AM, iPod), Shuffle, Reset (brings bass & treble settings back to neutral), volume up/down, track forward/back buttons, play/pause, independent bass and treble controls, playlist controls (the only real iPod navigation function available - limited, but appreciated), alarm on/off/reset, and the button most likely to get used... snooze/sleep.
The top of the Luna is adorned with four silvery buttons/knobs that control: Alarm 1, Alarm 2, Volume/Snooze/Source, and Dimmer/Alarm Reset/Menu. The recessed iPod dock is front and center between two of the silver control knobs.
Display
The Luna has a modestly-sized 2.75" diagonal screen which displays the current time, alarm times, radio stations, etc. The displayed text and icons are a cool, radiating white against a black background. It's somewhat soothing, which is great for a clock radio. The screen brightness can be changed with a rotating dimmer knob. In my personal opinion, the screen is way too bright for bedside use, even at it's lowest setting. A clock radio should be visible and pleasantly readable. It shouldn't illuminate an entire room or leave one with momentary night blindness. It seems that some lower-end clock radios have a built-in sensor that automatically dims the display at night and brightens the display when ambient light increases. The Luna would benefit from such a feature.

AM, FM, Etc.
Because some people still listen to AM/FM radio, XtremeMac caters to them with the AM/FM tuner built into the Luna. Folks can wake up to crrrraazy morning zoo baloney and countless ads should they wish to. Just plug in the AM and/or FM radio antenna into the back of the Luna and tune into your favorite stations. Granted, you may find that the radio reception isn't very impressive. I had to hold the FM antenna at about eye level to get one of the more popular stations in town. Setting the antenna down behind the night stand or onto the floor left the radio station with a slight hazy sound.
The Luna has a "line in" jack on the back for AUX input - think secondary iPod, laptop, powered karaoke mic, Zune (ha ha - as if), etc.

No More 9 Minutes
Thanks to the Luna's customizable snooze settings, you can forget about the arbitrary 9-minute snooze dictated by so many clock radios and alarms. Set your own snooze period - 1 minute for the highly motivated, 11, 22 or 33 minutes for the compulsive, or even 60 minutes for those Sunday afternoon snooze-fests.
Another positive feature is that the alarm, whether radio, iPod or otherwise, comes on gradually. There's no jarring blast to spike your heart rate in the morning - just a gently increasing reminder the get off your duff.
Docking iPods
Only 4G and 5G versions of the iPod can be connected to the iPod dock on the Luna, including the second gen Shuffle. It is very likely that the 6G iPods (and possibly the iPhone) will also dock with the Luna and other XtremeMac speaker systems. When an iPod is connected, the Luna will charge the iPod. If you are connecting a 2G Shuffle to the Luna, you'll need to use the super-handy Griffin shuffle dock adapter which will cost you about $14 in stores. Note that with the Griffin shuffle dock adapter, you'll have to periodically toggle a tiny switch from "play" mode to "charge" mode. This is because the 2G shuffle can't simultaneously play and charge on a dock at the same time.
Redundant Power
The Luna has a small battery compartment for two AA batteries. These won't power the Luna unplugged, but they will save the time, date, alarms and radio presets you worked hard to set up. In case the AA batteries die and the Luna happens to get unplugged, XtremeMac added a 5-minute redundant power backup to help keep your settings intact.
Wake Up! Really, Wake Up!
Ever wake up late after having unconsciously turned your only alarm off when you should have been getting your bleary-eyed self in gear? The Luna gives you a second chance at punctuality thanks to Alarm 1 and Alarm 2. You can set a second alarm for when you expect you'll accidentally fall back asleep. The second alarm is also good for couples who wake at different times. Alarm 1 and Alarm 2 can even be set to respond with custom settings. If you prefer to wake with your iPod and your significant other wants to wake to his or her favorite FM station, no problem. The Luna can serve up custom presets.
