Two subs load the room better. This creates a more seemless integration with the Sigs. It also allows for ultimately more total bass power(plays louder.) Lastly, some music has channel separation down into the lower frequencies. Two subs allow you to take advantage of this.
I have found that using two increases the soundstage width and and sounds more natural. It makes the system sound bigger with better dynamics.
I use the 3 Sigs with a pair of subs. It just doesn't sound the same with one.
