There are various options available. Choice depends upon personal taste, audition, etc.
I could not find which city you are located in. Depending on that you will get options for audition.
I personally prefer products from India authorised dealers because of 230V compatibility and warranty. But many forum members prefer to import for lower costs and puny 1 yr warranty in India which is probably not worthwhile.
Now getting to the components. If you already have source (like bluray player/nmedia player/HTPC, etc) and display (TV/projector), you will need AVR, speakers, subwoofer and cables. As a starting point you can consider Denon x2300 receiver at aroung 65K. Front speakers you can look at towers/bookshelves from Polk/Dali/Wharfedale/Elac/Q acoustics/Monitor audio, just to name a few. If you can't audition, browse through reviews in various forums. Center speaker should preferably be from same series as fronts. For subwoofer SVS PB-1000 (single) may be a good fit for your room and budget.
