EC: Yeah, throw in room effects and other off axis stuff, sure. I was thinking of a more "pure" case, right on axis. But if you measure a simple rolloff from a cloth filter (the assumption in Bill's question), it will not in any sense be "phaseless," it will be minimum phase- at that one point where you're measuring, as you imply.

You're probably right
SY: I expect you're right, and that it is minimum phase, but I wonder if anybody has made the measurement? (I'd do so myself, but my new computer doesn't have the right slot for the soundcard required by my old loudspeaker measurement system.)

Doing the experiment
I'll see if I can clear my wife, kid, and visiting mom away for an hour or two this weekend and give it a go.

Yeah, "noble." That's what everyone I know thinks of me. Not to mention "studly."
