It's highly recommended to do exactly that, especially if you're completely new to this hobby and have no idea what sound signature you like.
In which case, I'd recommend trying 3 speakers that offer contrasting sound signatures: perhaps a "warm" speaker, a "neutral" speaker, and a somewhat "bright" or "forward" speaker. Although if your usage is more HT/TV than music, you can skip the "warm" speaker unless you have a known sensitivity to strong treble and/or have a highly reflective room.
