speakers for Sonus

Hi, can anyone recommend speakers for sonus wifi- Main room will be approx 3m x 8m (long and narrow) and desktop speakers really needed. I might be able to get away with either small floorstanders or wall mounted ones. In second/third zones, very small bookshelf or in ceiling wall speakers might be best. Budget for main speakers- £300-500 inc. cabling and for others £100 per pair approx

Thanks
