Hi all,
I am posting this here since I think the question relates to room acoustics (how room shapes the sound at the listening position).
I know that subwoofers, that play lower frequencies (i.e. below 100Hz) send omnidirectional signals question is if they can be put further away from listening position (related to the main spakers)
The below attachment explains the problem:
We have two speakers at 1.80 meters apart and the ideal listening distance is at 1.80 meters. With Latin capital letters, we have potential sub-positions where cables can be hidden. Even though these might not be the ideal positions it does not harm to test those as well.
Positions C and D, top right in the figure are places that are further away from the listening position. MThe mainspeakers are 1.80 meters from lthe istening position and the C,D are around 2.5 meters from the listening position. Also, the subwoofer will be sending sound from the back of the listener's position.
1. Will that be a problem? Main speakers will have much longer cables compared to the subwoofer (subwoofer at position C and D is placed close to the main equipment). Then the sound itself travels a smaller distance from main speakers to listening position and of course, we have the room acoustics in the equation
2. What about going with a second sub in the future? For example position A(close to the main speaker) and then C or D on the other side and diagonally to the A.
What does the theory of room acoustics say about this type of setup? Do subs need to be somehow close to the listening position and close to main speakers?
Thanks a lot
Regards,
