Wow, that's quite low. I set my center and surrounds and Atmos to 100hz....

Hmm, maybe I should experiment with 80hz or even lower...

Maybe that's why I was getting very 'mono' bass with the high xo frequency..


When I set my C at 100hz  or even 120hz, I noticed, it sounded too dry compared with 80hz.
I used 'live by night and hulk', the shotgun and his roar/footsteps sounded heavier from my C (produced some bass) and machine-gun sounded heavy and smooth too from L-C-R..
(note: Audyssey gave full range for my L/R and 40hz for my C)

Nevertheless, I will try to set my L/R to the full range, no harm to try and find out.
Currently, L/R= 80hz, LPF =120hz (thicker sounds than 100hz).

How about lower C to 40hz, 60hz or 120hz? does it sound like 'bloated'?
Since I am using bookshelf for my side and rear surround speakers, therefore I set to 100hz
I am using satellite speaker for my ceiling atmos, I set to 120hz
(audy gave 60hz for side/rear surround and 80hz for ceiling)

Oh one more point, I only have one subwoofer.

I suppose folks with dual or quad subwoofer have the advantage on multiple VLF sources that reduces the localisation effect, therefore can set higher XO points...

Actually the reason I pushed the xo to 100hz was from previous testing. I wanted to maximize the subwoofer channel bandwidth, because I'm using capable midbass subs and wanted to make full use of their output. 100hz was about the limit, beyond that 120hz etc the localisation started to become obvious.

I suspect with a lower xo frequency like 40hz there may be less bass quantity compared to 80hz, depending on output capability of the mains.

Will definitely try 80hz xo.
