Given two or more subwoofers in a stereo system, what difference, if any, will there be between connecting the subwoofers in stereo or summing the channels to mono and feeding that signal to both subs? I have a little experience with this but not much and would appreciate any words of wisdom. Would it make a difference to the answer if the two subs were colocated or located with each stereo channel. I have only tried it colocated and not noticed any difference. I can think of arguments on either side, but I need practical advice. Dick

Group together outdoors, spread around indoors [message #28288 is a reply to message #28284] |

The best placement for subs depends on where you are.If outdoors or in a very large indoor arena, group the subwoofers together. If you can keep them close enough together (within 1/4λ), they'll act as a single acoustic source. If indoors, spread them around to average the effect of room modes. Reflections make virtual sources that cause unavoidable cancellation nodes. But by spreading the subs, you can make the interference so dense that it tends to average the sound field throughout the room.
