Hi I m a new audio enthusiast and would like to know whether seperate floor standing speakers need to b configured in the same manner as a 5.1 with four corner speakers and a centre channel with a sub-woofer
You really should do a little reading. Google "5.1 surround sound".
The idea of 2 floorstanders and 4 Atmos speakers isn't good. In anything mastered in surround, (this is mostly TV & movies), there is a hierarchy of speakers.
1) Most of the sound, and almost all the voices come from the Center speaker.
2) Next are your Left & Right speakers. These flank your TV.
3) Next are the Surround Left & Right speakers. These flank your chair.
4) Next are the Rear Surround Left & Right speakers. These are behind you.
Atmos adds speakers over your head. It's new and there is VERY little material available that is mastered in this format. It is debatable whether it will really catch on or not.
A subwoofer or two are of primary importance. That's the ".1" in 5.1 or 7.1. A sub(s) will make a huge difference in your experience.
One more thing. Floorstanding speakers can be better than bookshelf speakers only because they are bigger and allow for bigger speakers. It is not always the case. There are many bookshelves better than floorstanders. And with either, you'll still need a sub.
I suggest you root around in this site some. Do some searches. Read. Then ask questions about things you don't understand.
