If you mean by larger sweet spot, the ability of someone sitting to either side of the sweet spot to get a good sense of soundstaging width etc, and not just hear mostly the speaker in front of them.........
Before you venture out to get new speakers, often getting a larger sweet spot can be accomplished by simply positioning the speakers so that the axis of the speakers cross in front of the listening position.
Works very well with a lot of dynamic speakers, and other than looking odd there is little down side, in fact it also tends to give a bit better focus to the center image because of a possible reduction or change in side wall and ceiling reflection patterns. Try it, its free.
I do it in my room and folks sitting in front of the speakers get a credible stereo image, not as pure as the sweet spot, but quite credible non the less. A side benefit is that I can also place the speakers closer to the side walls because of the reduced effect of the 1st reflection points.
