On the down side, it's soon evident that there's just too much room in the sound - with the mid-range lacking in presence and definition. Turning the sub right down reveals why this is so. The drivers and tweeters in the speakers are far too harsh and rough and have absolutely no bass, meaning that the sub is being asked to do far too much. Rather than just filling in the low end, it's acting as the mid-range too, which it just patently isn't good enough to do. While the sub isn't awful it's not getting any help from the speakers.
Listening to the speaker set in the office proved to be tiring, with the tweeters speakers sounding harsh and rough and slightly unpleasant. In a smaller room though it did sound more rounded and not too bad. However, turning it up, the sound got woolier, and lost the sense of space I mentioned earlier.
Overall, it's an OK audio experience but certainly not great. On the audio side I'd recommend spending a bit more and going for this set of Acoustic Authority iRhythms A-211 speakers. They didn't get an outstanding review at the time, but that was based on the price of £199 - now Scan are doing them for just over £100 so it's a better deal. You won't get the benefit of the video out though, so if that's important to you then these speakers are worth considering.
A slightly odd looking set of speakers from an unlikely source. They do a reasonable job and the video out feature for a compatible iPod could prove useful but on the audio side there are better choices out there.
