Im after a few opinions as to how far back "delay" speakers need to be before it is necersarry to actually delay them in processing.
I am designing an installed system for a fitness club spin studio (indoor cycling) in a 10x10 meter room, which will have 3 or 4 rows of 8 bikes.
my plan was to have a second set of speakers halfway down the room to reduce the levels required coming from the foh and increase the vocal inteligebility in the back to rows.
The second set of speakrs will be 4 or 5 meters max from the foh, so at this distance is it necersarry to time delay the rear speakers, or will it not be noticable enought to justify the additional amplification/processing?
Appreciate any input.
