Audyssey XT Room Calibration help....

I am wondering why when calibrating all 8 seating positions with my Onkyo Pro SC-885 pre processor it calculates the distance to near perfect but the crossovers are so out of wack. Speakers are Paradigm Signature S1's,C1,ADP1's - EG: 120HZ for rears which are crossed over at 70HZ, 120HZ for center and crossed at 60HZ, and fronts at 90HZ which are crossed at 58HZ. Should I just put them at full range or leave the settings as is????

ALSO: When a new installed powercord(s), interconnect(s), speaker cord(s), or component is connected to your system and you have prior calibrations should you re-calibrate with the new addition???? Any help would be appreciated...

I do not understand your numbers as expressed but none of those speakers are full-range and should be crossed over as recommended. Note that the so-called low frequency limit advertised was not measured in your room.

"powercord(s), interconnect(s), speaker cord(s)," make absolutely no difference. No need for recalibration.

Other component? What other component?

The frequency ratings for the above speakers are: Front-72hz-45khz,Center-73hz-45khz,Rears-99HZ-45KHZ. The Audyssey calibration at:Front 90hz,Center 120Hz,Rears 120HZ.I meant that if you replaced an amplifier or pre/processor with different specs(eg: S/N ratio, db ratings, power ratings)....Would you then need to re-calibrate????

Audyssey's recommendations do not seem unreasonable as they take into consideration your room's acoustics and the performance of the speakers as you have placed them in that room.

If you replace the amp or processor, you should re-calibrate although the reasons have nothing to do with "(eg: S/N ratio, db ratings, power ratings)."

The quality of sound could be far different...The db could efffect the volume from the speakers if greater or less. The spl could too. The power rating could effect as well with the db rating. Correct.

To be precise, the sensitivity of the power amp could affect the balance with the sub. SPL/Power are not relevant.
