Its good Ramesh. Congrats on your setup and sharing the photos.
About the components used, kind of experience you had and other details will also help people like us to know more about the setup.
I see that you have placed the sub woofer lying down inside the rack. If this is side firing sub, please see of you can place in on a hard surface such as the floor, and in an upright position.
You have a good components set. 2 things I notice with your speakers set up that should be changed:
1. Move them a bit further from the floor as the reflecting waves will combine with those with the front and cause highs/dips in the listening ares
2. The spkr near the window should be oriented towards the center of the room. Otherwise its waves will be out of phase with the next one. Best way to think about this is that the speakes & you in the center of room should form an equilateral triangle points. This should iprove the overall sound stage.
Lets us know how it sounds
the user manual says there should be a minimum distance of 2 metres between the front speakers, any suggestions?
