Wiring Delay

hexumjunkie

Sorry to bug you all again but i guess thats why I am on here to learn at a young age..soI can pass the knowledge to new pollkies 30 years down the road.

my question is I have a 7.1 setup with the speaker wire runs of a 100ft each. the reason there so long is because i havent moved yet and dont know how far ill need cable wise when i do. now these speakers are prolly only 11 feet from the front of the tv should i set the delay at 100ft each? thanks

No, the signal travels down the wires at about the speed of light, whereas once it hits the speakers, it travels at the speed of sound. Set the distances based on how far each speaker is from your head.

100 feet is getting a little long, so you might have some signal degradation, especially if you are using less than 16 guage wire.

No . The delay is based on the physical distance of the speakers from the listening position. According to the responses to another thread it appears that the signal will get to the speakers hooked up with a 11' cable and 100' cable at the same time based upon the limitations of human hearing.

The actual sound waves coming from the speakers is distance sensitive...therefore the need to adjust the delay so that all sound is reaching the listener at approximately the same time.
