[guruji007]

Hi Guys,
I am new to this forum and with not much knowledge about the Music System / Home Theaters.
My room Size is around 29ft* 11ft. TV viewing distance is 15 feets.
I have already bought an AVR - Yamaha RX-V781 (with the help of the reviews)

I need help in getting the Speaker and Subwoofer(If required).
My Budget for Speakers/Subwoofer is around 40-60k

All the suggestions are welcome. Also let me know, where in Mumbai should i purchase these speakers.

Thanks in advance.
