I need to buy a home theatre from scratch (DVD, Sub, Speakers) for the Australian Club in Dhaka. I have been reading about home theatre for last couple of weeks but unable to decide the best option. The problem is in my country there is no shop that sales speakers like- Harman Kardon, Onkyo, Klipsch, Martin Logan, etc. So i can't test them myself. I will purchase them from Australia. The following are the conditions i need to fulfill-
1. The room is 30 feet by 55 feet with open on three sides.
2. All the speakers must be wall mounted.
3. I prefer 5.1 or 6.1
4. I prefer the components from one or max two vendors, so easy to setup and control.
5. Total budget is not more than 4000 Australian dollars.
Since the room is very big and open, i am really confused what to get. I will be really grateful if you could help me with your expert advise.
