Marik, very good info, thank you! PE does indeed list the ECM8000 as an "omni" mic. So the cal file really isn't to correct for teh deviation as much as for use as a free field mic aimed at the driver and doing MLS type measurements. However with any other types of measurments that have some element of measuring the environment you wouldn't want to use the cal file. I'm glad I know this now!
The comment about the Radio Shack meter is interesting. I have a newer one and don't remember what the manual said about how it should be aimed. I need to check this out.

Marik, Would your modified ECM8000, more musical, change this from a pro measurement mike to a musical only mike or would the Mod also improve it as an measurement mike.

I have the M-Audio DUO USB for my ECM8000, but I can't get the computer to see the record inputs of the DUO. Output works great.
So I have to use the DUO in "stand alone" mode and come line out of the DUO and into my Turtle Beach card. Kind of a stupid way to do it - but it works.
Other than that the DUO seems to be a great USB DAC and mic preamp with phantom power. If only I could work out the driver problem.
I got the ECM40 today.
It's actually a bit smaller than ECM8000, and it's also quite a lot lighter, which makes the ECM8000 feel higher quality, but I guess this makes no difference.
Here's the size difference:

And here's the calibration data:

Looks cool - do you have a thread or a web page about this speaker? I'm thinking of doing something similar. I have a variety of Peerless HDS woofers and thinking to order some Vifa XT tweeters to try them (with and without waveguides).
I just "calibrated" my ECM-8k for 1k up using a calibrated reference (A mitey mike that was cal'd by D'Appolito years ago.) Mine has a slow rise to a ~1dB peak at ~12k, followed by a drop to 0 at ~15k and approx a 12db/oct rolloff above that. Mine is an older one - perhaps from 2002 or so. THere are a fair number of ~+/- 0.2dB ripples in my plot, perhaps I need to do some more measurements and average. They actually got worse when I put some foam near the neck of the mic.
