I would use masking tape to mark the sub location so that it's easy to place the second sub there. Try not to move your boom mic between sub swap. Place both subs back to where they are supposed to be and run Aud cal.
This isn't making sense to me. Both sub gains are identical and I verified this last night when I pulled them out to swap their positions. Once I run the calibration Audyssey is going to see again that one sub benefits heavily from the two adjacent walls and the other does not, so there will be a gap between the two gains. Just my thoughts.

Thanks Teach!

I have thought about an AT screen, but my room has limitations due to the size and vaulted ceilings, so it would be no easy task. I will have to give it some more thought. It would definitely be a lot cheaper than buying a 70" LED and also have a much bigger picture.

^^ you are missing the point that just because both gains are at the exact position does not guarantee both subs are at the same level. This is why I suggested you above to use REW tone generator to gained match.

Okay I'll take your word for it and try it. Anything special I should change or adjust in the generator? Obviously I will check the sub cal.

All of these has more output than my FV only if they were running 6 to 10db hot at close to reference MV. They were really pounding and pressurizing the room. My FV pair can really damage my room and the room next to it plus everything below it if I crank them to reference. In my opinion, the FV pair should be enough for most people minus most AVSer's (you are one of them). Remember the FV is categorized as for extreme large room by audioholic, so a pair of FV should be plenty for your room. If I were you, I wouldn't upgrade to the Echo18 and find yourself upgrading again as you have been doing. Why takes a small step? What if after getting the Echo18, there is a FV18hp, Echo218? Upgrade again? These forums are great but very bad for the wallet if one does not draw a line.
I thought I responded to this, but I guess I never did. So let me get this straight your telling me that unless I listen at very high volumes or run the Echo 18 very hot it will have no advantage in output over an FV15HP? It has more displacement a bigger cabinet and a more powerful amplifier.

1. Set both sub trims in Avr to 0 as starting point.
2. Set Avr master volume to 0.
3. Turn off aud.
4. Open REW spl tool and click the red button. Drag this window to a spot on screen so you can see it.
5. Select hdmi out 4 in REW preference.
6. Open REW signal generator and select pink noise, sub cal with -30db FS RMS level.
7. Click the green play button and observe the spl in REW spl window. I assume you already place one sub in the middle of your room by now with umik directly in front of the middle of the driver cone. Adjust the sub volume knob till achieving 90 or 91db (hdmi out 4, which is the lfe channel, is 10db higher than speaker). When I mentioned achieving 80 to 82db in my earlier post is when you use an external spl meter. Put sub 2 in that same spot and keep the umik untouched, do the same till achieving that same value as sub1 recorded earlier. Note that the spl value in REW (or an external spl meter) will be fluctuating by a db or 2. Try your best to get both sub (one by one) at that same level.
8. Place both subs to where they are supposed to be, run aud first mic position and select calculate and save.
9. Check your sub trim levels and report back.

Your list of words misused is on point, when reading I find myself slowed/stopped when the wrong word is used with a totally different meaning and having to go back to see the context and then understand what they really meant.

Hey guys, should I use the included rubber feet on carpet or are those only for hard floors?

Can I just let them sit on carpet without any feet?

I don't use mine and find that it makes it much easier to move them around on the carpet. I'm pretty sure they are only for hard floors.

Yeah I definitely wouldn't put them on until they are in their final resting places. I'm wondering though if the hassle of putting spikes on them is worth it.

I have them on my speaker stands so they have a stable footing. On a sub I'm not sure.

It's amazing how low Audyssey sets my subs. At the 75db calibration, it put them at -10. I had to put them up to 0 with DEQ on just to get normal bass with music.

Comparing high and low damping now.
