Difficult Calibrations- Listening to the cal signal to help figure out what's needed for success...
Speaker placement affects low output...
If the woofer further away from any room boundry (wall or floor), the xover point will rise. The issue appears that you have to compromise. Either have the woof lower or the tweeter at ear level. Try both, see which you prefer. Each may have it's benefits, and to predict the better is beyond the scope of a short answer:).
Cal Signal is always the same...
Rear left: Trinnov Cal signal does not vary. Correction is not applied to that calibration signal, only to the results. Good call on listening to the cal signal. You are hearing differences in the speakers.
Listening to the Cal Signal for clues...
Observing the cal signals is a very good thing: if cals are problematic, get behind the cal mic as the cal takes place. Listen. You'll hear all frequencies if you listen for them. In particular, for the higher frequencies (like hiss). Move your head as you listen, to see if the sound changes. If the speaker does not provide ample hi frequency output, it will not be found. Listening to dipoles, from the middle and from the sides, can be very telling. See the above note as to why the speaker is not being found. If a speaker is found immediately, you will hear 3 bursts. If more, then it's a good idea to listen. Compare an easily found speaker's cal sound with those of ones that require more bursts. Again- move your head to observe a difficult speaker from varying angles. You may get just the clue you need to get your system up and running. See notes above on di-poles for more clues.
Cheers,

Trinnov sets the roll-off point for the center at 80hz, but the L/R at 120. I have them flipped upside down (due to limited placement options) to keep the tweeter closer to ear level. Do you think the low end is falling out due to it's closer proximity to the ceiling? Would unflipping them, effectively putting the tweeter closer to the ceiling, give me better results since the 3D correction will hopefully bring the soundstage down?
Also, my rear left speaker doesn't make the same test tone noise as the rest of my speakers. It did for the first half a second, but every recalculation after that, it made a slightly less powerful sound than the rest (not volume, but texture). Did the receiver incorrectly mark my speaker out of phase and swap the polarity? It took 6 complete calculations for the Trinnov to come up with H and V angles for that particular speaker. The first 5 it only calculated distance. Any trouble shooting tips to help resolve the problem?

Cheers,
I have checked and rechecked the settings and performed many resets. I would be very grateful if somebody could come up with a "magic fix", that would be awesome.
