You can use REW to measure impedance and electrical transfer functions too (since Ver5). Nice link on impedance measuring:

REW is great, but measuring the speakers adds a ton of confounds. I say this as a speaker maker and integrator. And that's fine, but what I'm personally after is to understand how well these amps do electrically, as that will be the most clear.
