my son will be running two subs soon and has a 15 ft. and a 35 ft. cable ... will the 20 ft. difference between the two cables matter ?

It shouldn't matter. The signal travels at a speed close to the speed of light so a few feet difference should be of little to no significance. The 35 feet one is on the long side for RCA but should be ok.

In insulated wire it's actually about 0.7C, but as that's about 130,000 miles per second latency wouldn't be a problem unless the difference in the wire lengths was on the order of a few thousand miles. Give or take.

Hi, Bill,


Would there be no degradation in the signal with those lengths of cable?
A tad.


But I doubt any of us have a listening room large enough for it to be a major concern.

If he could get by with a 25 ft cable, since 35 ft is quite possibly a bit too long, would it be advisable/worth buying a 25 ft, $17 Mediabridge ULTRA? It would be for the second of his two SVS SB12 NSDs.

Not sure yet how far the second sub will be from the AVR.

Only if there's no place to hide the extra wire. Line level signals have no issues with even 100 foot runs.
