Audyssey calibration: one point or many points?

I do the Auddessey setup and then trim via SPL.
I use a Radio Shack SPL.

Should I just let the Auddessey mic do the job instead?

You are right; the Audyssey mic is indeed more accurate than the Rat Shack SPL meter one (within +/- 1.5 db across the full audio frequency range).

* In my setup I let Audyssey set my Speaker Distances & Levels, and I leave it there. I also have the Rat Shack SPL meter, but I don't use it no more now, now that I got Audyssey (only to calibrate my two subs).

** The only thing that I do manually, is to reset all my Speaker x-overs to 80 Hz (Front Mains, Center & Side Surrounds), and to 100 Hz (Back Surrounds).
>>> But you can only change them going up, and not down.
EXAMPLE: If it says 60 Hz for your Front mains, you can go to 70-80-90-100 Hz. But you cannot go to 50-40-30 Hz.

*** And I do add 1 dB to all my Surround speakers, for personal taste.
- And for some movies I might add 1 dB or so to my Center speaker.
- And I added 0.5 dB to my Subwoofer channel, just for that little extra preference boost.

YEAH, let Audyssey take care of your Speaker Levels, it does a better job than the Shack meter.
But do readjust your Speaker Crossovers manually though (aim for 80 Hz, which is the best x-over point in my opinion, and the one from the Pros), depending of your speakers of course (if their woofers are just a 3" driver, you want 150 Hz or some like that for the proper x-over).

BONUS: Read that Audyssey Setup Guide, from the link in my signature.

Audyssey!
