What makes speaker's sound big?


Does a speaker need to have many drivers or a large driver area to sound big and fill the room?
I am asking this question because I have a pair of tekton design double impact and would like to replace them with smaller speakers and a pair of subwoofer's to better integrate the bass into my room.
I just borrowed a set of B&W 702S. The are good but the just don't make that floor to ceiling sound that I like.
Maybe I have already answered my own question (: But again I have not heard all the speakers out there.
My room measure 15x19' and the ceiling goes from 7.5 to 12.8'

i agree with you

each speaker design, even ones purporting to be cost no object or state of the art, has inherent tradeoffs. strengths and weaknesses

let’s not confuse a speaker set sounding ’big’ with them sounding ’real’ - i.e. like real musicians playing live music

stereos largely downscale and recast the recorded music

someone wisely said -- ’it all sounds fake... we are all just picking the flavor of fake that we happen to enjoy’...

That is another debate....It is not the precise question of the OP.... How a sound could fill the room ?

Not, how a live performance could be equal to a stereo system ?.... It cannot.... It is like caned tuna and real tuna around a boat.... The same fish not the same recipe.... 😊






It seems i answered your post too speedily.... I apologize jjss49  ...

And you are right all speakers need their own space and needs...

My best to you.....
