Hi there stefn and welcome to the forums.
You don't mention a budget for you speakers. I am assuming you want a full 5.1 package, and not one thats too pricey, correct ??
Have a look at
THESE from richersounds. Have had good reviews in the past, no longer "cutting edge" but would be a good start for a surround system.
Alternativley, have a look at all the packages RS do
HERE to see which fits for budget best. You could build up a 5.1 system by buying the speakers seperately, BUT, do try to keep the front three matched for better tonal intergration. You say your room is not too big, so a sub/sat package like the Tannoy should suit you better than a "full size" setup of say, a pair of floorstanders and stand mounters, plus a centre and sub.
You could go down the seperates route if the room size would allow the use of four stand mounts (front L/R and surround L/R), a reasonable sized centre, and a small to medium sized sub. This route would allow for (usually) a better quality of sound (especially with music), and allows more scope for upgrading as / when funds and circumstances allow.
All the best in your search,
Graham.
