Hmm, my understanding was that together kept the crossover in mind, meaning the measurements are ignoring the L+R+C readings below 60Hz if my crossover is set there. Hence the reason they all essentially look the same in the first graph up until the original 80Hz crossover point.

But yes, together I can get them down to where need be.

EDIT: Actually you're right, they do begin to differentiate before the crossover. Either way, I guess I'll have to play with it quite a bit.

Does anyone have a house curve answer I was referring to earlier? Across from 15Hz-20kHz, do you really want the whole thing to be flat? Or do you want it to slope off as you go higher? I have a feeling it's going to sound too bright if it doesn't slope off.

And how do you determine what this slope is?

Generally speaking, most people prefer a bump to the bass and a rolling off of the treble. Picture pouring water on the bass end of the graph - it should be able to find its way to the other end and drain off.

Expect to hear disagreement on this, as it's been discussed in the Audyssey thread (and others, I'm sure).

That's why it's called a house curve, it depends on your house.
The idea is to calibrate flat, which is the reference from which you can start.
Typically, there's a boost at the low end (I'll say 6 - 10 dB) with a smooth slope that ends around 100 Hz. Then it's flat.
And, yes, there are some people who like a drop off at the high end. At my age, I can use a little extra treble.

Well shucks, I did not account for this when measuring. Can boosting the subwoofer hotter from the AVR yield a similar result without having to adjust too much in the P-EQ settings?

Yup.

Here's an awesome article on the subject over at HT Shack from the resident guru, Wayne:

For tweaking the crossover region (overly all to find the best crossover):
  • C (15Hz-20kHz)
  • FL (15Hz-20kHz)
  • FR (15Hz-20kHz)
  • Sub (15-300Hz)

Not needed (IMO):
  • FL + FR (15Hz-20kHz)
  • FL + FR + C (15Hz-20kHz) <---you would not be able to accomplish this if you are using HDMI because you can only output to 2 channels + sub at once
  • FL + FR + sub (15-300Hz)
  • FL + FR + C + sub (15-300Hz) <---you would not be able to accomplish this if you are using HDMI because you can only output to 2 channels + sub at once
If I use my setup for both 5.1 movies AND stereo 2.2 for music, am I in error to think that both subs with mains (L & R) is an important measurement. I do my most critical listening with music. Thanks for any clarity.
