It really depends on the speaker and associated amps, but bigger speaker enclosures generally make for better reproduction of lower frequency sounds. Of course, it doesn't necessarily follow that the speaker will sound good.

When a couple who has never been to our house before walks into the family room, the guy usually stops to stare at my 6' 6" line arrays and says something like "Man, you must like to play your music loud" or "you must like a lot of bass", both of which are wrong. I just like my music to sound undistorted at room filling volumes.
The woman usually says something like this this to my wife: "You let him have those things in this beautiful house"? I have trained her to reply "Yes, size does matter, and I like a big one".
I don't really care what shortcomings they have because I can correct it before it even hits the speakers.
I think might upgrade them to Cerwin Vega XLS-215's one day though. The advantage is that they get down to 24hz, while mine get down to 35hz. They stop at 20Khz, while mine stop at 40Khz. I am pretty sure some crossover surgery can get them to pass 20-40Khz though the tweeter.
Again. If you insist on amplifying the original source to line level, then sending through a power amp untouched, big nasty loudspeakers might not be for you. But if you have a half-dozen processors that can make a signal as flat or as coloured as you want it, the speaker size becomes a limitation if they are too small.
