The sound quality can be affected by the distance of the speaker from the source. However, it's not always possible for outstanding audio quality. It would be best to keep the length of cable tethering your speakers to your receivers closer even though your sound quality won't suffer that much unless they are 25-feet plus from your receiver. Kindly use a 14-gauge cable for any wired speakers or a 12-gauge cable for any speaker extending over 25feet from the receiver.
