Test CD for positioning speakers and subwoofer

I worked out a procedure to locate speakers (nearly full range floor standers) with a Stereophile Test CD and RS SPL meter.  My meter is placed on a tripod at ear height at the listening seat position.  I record response throughout the 200 to 40 Hz range (after setting level for 80 dB at 1K Hz) for each position, moving speakers forward in 2" increments from the front wall.  I then add up the deviations from the 80 dB reference and compare totals for each speaker position.  This is to locate the smoothest bass response, not necessarily the deepest range.  I've found this quite satisfactory.

Regarding the Rives Test CD, I believe their supposed correction for RS meter readings assumes too much precision from the RS meter.  I doubt very much if at that price, RS could offer a meter with such consistency from one to another that an absolute correction is possible.

And so I consider any readings I make with my RS meter to represent relative data rather than absolute.

I use test CDs to see where speakers roll off mostly for amusement purposes only, as my ears still work as the only truly valuable speaker positioning aids.

Lots of good suggestions above.  If you still can't get things dialed in completely to your satisfaction, or maybe even if you can, I'd recommend finding a way to demo something like the DSpeaker Anti-Mode Dual Core room correction device.  It may yield even further improvements above integrating bass and save you time and headaches.  Best of luck. 

First, ask GIK Acoustics for help. Best products at the lowest prices and great advice.

Once you have taken all their advice, you'll need OmniMic or Room EQ Wizard. The reviewers at Stereophile have been using OmniMic more often, but they don't know what they are looking at yet. :)

Anyway, the Room EQ forums are filled with good advice about sub placment AND EQ.

Look at miniDSP for your subwoofer EQ.

That is all.
