Sorry, I'm so busy with my book I haven't been visiting here much.
I disagree with the advice that this or that speaker is too big for a given room. What matters most in that regard is the LF response.
Bass traps are good almost anywhere, but mid/high frequency absorbers behind speakers is not usually warranted. More:
Front Wall Absorption
I'm a huge believer in specs, but when it comes to speakers, and wording like "wider sweet spot," I'd want to hear them in lieu of hard data showing off-axis response at many angles. Plus, a near-field setup doesn't necessarily benefit from a wide sweet spot unless you move around the room a lot while mixing.
