Welcome. I will assume you do not live in the U.S., so it would be difficult recommending audio equipment without knowing what is available where you live. What I can say is that with approximately 90 cu. meters to fill, your subwoofer requirements will probably be above average. I can also say that small, bose-like speakers won't give you very good audio, but decent bookshelf speakers will. Take a look around your area and see what is available for your budget and go out and audition a few speakers.
