Yes, I have a tripod. I didn't take 6 readings, as I only have seating for 4. I've rerun that a number of times.
In response to other questions: I had played with the crossover settings and tone control and nothing seemed to give me any kind of satisfactory mid bass. I understand part of the problem is a 5000 cu. ft. room and subwoofers that could probably be better placed in terms of sound. However, 80 Hz is right at the threshold of where sound can be localized. I had thought about putting the subs in the corner of the room almost 20 feet away, but rearrangement of furniture was low in WAF. But my wife and I were wowed by simply swapping out the front pair of DefTechs with the Ohms that came in a month ago. Last week I received the Emotiva preamp, and I couldn't help but notice the improvement in intelligibility and naturalness of voices in the center channel speaker, and I haven't even run the Emotiva room correction yet, just using the flat setting. So now I have this weird totally unmatched setup with Ohm MicroWalshes in the front powered by Wyred 4 Sound 250 watt (actually, more like 500 since the Ohms are 4 ohm) monoblocks, The center and surround speakers (Mythos 7 and Ones) are now powered by the Pioneer SC-07 that I recruited from my bedroom using the multi-channel input. It would be nice if I could somehow turn off the preamp in that receiver and just use the output amp, but I'm not sure that's possible. I can't wait to get 3 more channels of dedicated power amps, and return the Pio back to its rightful place. My system components are inside a wooden cabinet and I do have to worry about heat, hence the Class D power, which costs a few bucks. The A/B Marantz had always made me feel a little uncomfortable with that.
Also, I thought at the time, circa 2009, that the STS used the same drivers at the Mythos One with an added subwoofer at the bottom.
