I'm helping a friend put together a 2.0 system for a large room. The layout of the room will only allow for a 2.0 or 3.0 system. A sub might be added later, but probably just stick with a higher quality 2.0 system. Ideally would like to spend around $1000-1500 for the speakers, but will go up to $2k if increase in quality is good enough.
Current models I am considering are the Paradigm Monitor 11 v7 ($1500), and MartinLogan Motion 12 ($600, newegg).
He's not really that much of a critical listener, so leaning towards the MLs, and having him add a bigger TV, or something.
