>>You know the family and I were planning on a big visit to Iowa next spring to spend time with you, but since I am SO susceptible to discrepancies in the 120-150Hz range and you are obviously unwilling and/or unable to actually show some sensitivity to my plight, I think we better just call the whole thing off.

Speaking of "are we amused", you just made me blow tequila out my nose. I hope you are happy

Seriously, I don't think this is so bad. All kinds of high quality audio systems <Bose> have big dips in this frequency range and people are really happy with them...

Something just popped into my head, isn't there some RS Meter corrections or something like that, wouldn't that change my results?

OK, I think I found them for the latest analog meter on Home Theater Shack, providers of RoomEQ Wizzard software. Appears, it might help a little in the 20-40hz range, other than that it is pretty close.

Randy, you're the best. We're going to have a good time one day.

But, you know, the Rocky Mountains run through Colorado, right? How about as-flat-as-Kansas?

John, NOTHING makes me happier than getting you to shoot tequila out your nose. But JP is trying to help me out.

Randy, thanks for the rows and columns. I don't get quite enough of that at work, so I appreciate you inserting data tables into my leisure time.

Randall ... how tall is your ceiling? In the awesome pictures it looks very tall but I thought yours was a basement system? If I haven't already said it, man your room and color combination is extremely nice!

The Rives test cd is also pre-corrected for the RS meter, which is nice. I don't think it works very well though -- the CD has been sitting shrink-wrapped on an M60 for two weeks now and my system doesn't sound *any* better.

Rick, the ceiling is 9ft 2" tall, and yes it is our basement HT/Recroom area. If you look at the pictures, the screen area is set back about 6ft from the rest of the room. You can see on the right side where the AV equipment is, how it then blends into the larger room, which is 900 Sq Ft. overall.

Tom, when I said "Flat as Colorado" I was being sarcastic, , meaning I most likely will never get a flat chart no matter how hard I use Access and export/import data.

Isn't that a pretty tall ceiling height for a basement? Forgive me if I sound stupid but basements are completely non-existent down here in south Florida.

I did some manual graphing today using the Rives CD and charts and although crude compared to Randy's presentation, I'm curious what you fellas gather from this chicken scratch ... that is, if you are able to read it.

Wow, scanning, picture posting ... SPELLCHECK! I'm beginning to feel like a real computer wiz.
