For such a slim speaker they sound great with music. They are designed to work against a wall, but will sound best when married with a decent little sub to fill out the low end.
The Radius range are small speakers, so will lack bass compared to a hi-fi speaker.Do you have an example for a good (but smallish) sub? I have just finished mounting my R225 and R250 (centre) and am a little bit dissapointed in the lack of bass.
