I own some decent bookshelf speakers that have good sound quality. I position them well within my room, symmetrically a few meters in front of my desk.
I have recently been to other places that have large speakers, probably 10x or 20x as large as mine in area. And even on a low volume -- comparable to normal listening from my bookshelf speakers -- the experience feels physically different, like being bathed in diffuse sound as opposed to the audio coming from two centers.
Maybe it's the acoustics of the space or whatever else, but I want to ask: beyond loudness, does speaker size matter? Do larger speakers achieve finer sound or better spread sound waves in a room? In other words, between small and large speakers of comparable quality and price, should you elect for the large ones?
