When I first ran Audessey it set the subwoofer distance settings at 23’. I sit 11’ from the subs. I manually set the distance at 13’
This morning based on something I read here, I in increased the distance to 18’.
WOW!
The subs are coming through me in HT! Watching Venom.
Can someone explain the why? How can I find the sweet spot for the distance? Thanks
You can find the sweet spot with rew! Lol
The reason it was set to 23’ is because that’s how audyssey “sees” the subwoofer. So you sit 11’ away, now you have to add in the processing time and the length of time for the waves to get to you and it adds up quick. Sound, iirc travels at 1’ per millisecond. So the farther the physical/acoustic distance, the sooner it fires the subwoofer. This keeps it in time with the rest of the speakers.
Also, changing the distance changes the delay which is phase. Many times there is a dip in the XO region that can be filled in by adding some distance. This can help with impulse response too.
Without proper gear, finding the sweet spot will be hard. I’d start with audyssey setting and add a couple feet at a time and see what you get. An spl meter and test tones can be used too.
