greetings to all the sifus here

right now I have an onkyo nr609 in a box and ready to be used in my new home theater next month... problem is I'm new to all these stuff and I have absolutely no idea on what speakers to buy... any clues/hints?? It will be a 5.1 setup for 90% movies and another 10% for occasional music... and higher preference on bass (i LOVE bass )

I have done some googling and love the looks of KEF Q500 + Q200c + Q100 but still not sure on the subwoofer yet... budget is ~RM5k... do you guys think this is doable?
