The dome speaker enclosure on the Edifier Luna 5 Encore actually houses five magnetically shield drivers. There's a sub unit along with two mid-range drivers and two tweeters. All this adds up to 52 watts of RMS power.
However, the Luna 5 isn’t particularly loud, and while the volume level is fine for an average-sized bedroom or office, we found it struggled to fill a reasonably big front lounge. We wouldn’t like to rely on it for loud music at a party. Thankfully, though, it does tend to hold together quite well at louder volume levels, with distortion only really creeping at very close to maximum.
Also, the dock does, for the most part, deliver quite pleasing audio. Bass is tight and focused while the mid-range is naturally vibrant and highs are clear without sounding overly sharp. This is true across a range of different music types from the more subtle acoustic work outs of Midlake's Courage of Others to the bass heavy stomp of Leftfield's Dub Gusset.
That said, stereo separation isn’t great, so music doesn't sound as wide and expansive as many other docks that we've tried.
There are a few other problems too. Although Edifier says the dock is compatible with iPhones, our iPhone occasionally threw up an error message when we plugged it in, saying that the dock wasn't designed for use with it and asking whether we wanted to turn the airplane mode on to reduce interference. Nevertheless, music playback from the iPhone still worked fine.
A more worrying problem, though, is that the FM tuner is nowhere near as sensitive as it needs to be. The built-in antenna is so bad that it just doesn’t pick up many stations. Using the dock in East London, we couldn't get clear reception of XFM and couldn't get any reception at all of BBC Radio 1. Clearly the radio section just isn’t up to scratch - don’t buy this dock if the radio feature is important to you.
The Edifier Luna 5 Encore has its strong points. Its audio quality is better than many similarly priced docks and its design is distinctive enough to help it stand out from the crowd. However, it's hampered by the poor radio reception from its FM tuner and that it's not quite loud enough to be used at parties.
