I just got myself a new surround installation:
  • 5x B&W M1 (same speaker for center, front and back)
  • SVS SB12-NSD
  • Denon AVR-X2000

I first ran the Audyssey setup resulting in the following crossover settings:
  • center: 60 Hz
  • front (L/R): 80 Hz
  • back (L/R): 110 Hz
  • subwoofer: 120 Hz

I was surprised to see different settings for the 5 speakers.
Is this normal because the 5 speakers are all the same?
And is the setting for the subwoofer not too high?
What if I change this value to e.g. 90 Hz?
I still have overlap with the center and front-speakers but not with the back-speakers.

When I listen to speech/voices (through the speakers), it sounds clear and at a good volume.
If the speakers also need to produce "bass-sounds", the volume of speech/voices is noticeable decreasing.
Could this be caused by the crossover settings?
Or can this be related to the dialog level (+3dB) or dynamic volume (Medium) settings of my receiver?

Some advice for a newbie would be useful.

First I would say set all speakers crossover to 80hz then use your speakers for a while and let them break in. After a week or so then rerun Audyssey. See if the crossover settings changed any. Ideally you want to have all speakers crossed over at 80hz. But if you select a crossover lower than what Audyssey determines then you have no EQ from that point. And the sub at 120 is where it should be, that's not a crossover that's a low pass filter (LPF) of the low frequency effects channel (LFE channel). So with those settings anything 80hz and below is getting sent to the sub from the speakers, but the LFE channel has freq up to 120hz so by setting the sub to 120 you are allowing it to play everything that it is supposed to.

You are getting different crossover settings because Audyssey is pretty smart. Its not just testing each speaker, its testing each speaker with respect to how your room makes the speaker sound. Because your speakers are placed at different places in the room that is why your getting different crossovers.

As for Audyssey settings, to each is own. I use Dynamic EQ with reference set to -15 db and I have DYN VOL OFF.
