@jammymalina what is the size or your open space? i will be in a similar situation soon (80sqm, 860sqf) and am following with interest. Thanks.
I have exactly the same (82m²) with a little higher ceiling as my dedicated listening room.
And although it's treated and my listening distance is 2.8-3 meters any 2-way or small tower is like a candle in the dark,can't do justice to it.
The same with all rooms at about this size I have listened to.
What does it is big 3-way good from 30s to 300Hz for music.
Subs and satellites don't do it,no matter the configuration and the number except they can do good 300Hz,they are low distortion and are put under or near the satellites (in a W371 fashion)
That way it may have the energy it must have at midbass.
Bigger rooms don't need abysmal lows to fill,they do need enough woofer area though.
One must also prepare for elevated RT,which can go down to a decent (for the size) 600-700ms but to push it down to 300ms as some music genres ask for is a lot of work.
For my genre (classical) is ok though.
And another,such a space often tempts for a very wide speaker placement and it's one of the mistakes people do as it's first impression may be nice.
But will loose depth and image big time,no matter the dispersion of the speakers.
