There are none below 10k.
Alternatively, you can get a optical to analog 5.1 converter for 3.5-4k ebay/amazon india and use any 5.1 with analog in. Eg. F&D 3000U at 5k
After having spent a Lot of time hunting for such speakers, I learnt a couple of things. Such speakers do not exist and if they do, they have terrible DACs in them to produce close to decent sound.
I would recommend picking a basic AV Receiver and building your 5.1 system over a period of time. This would assure good connectivity, quality 5.1 decoders and some peace of mind.
