So my center channel randomly gets distorted where it sounds really distant and muffled. Sometimes it doesn't correct itself, but cranking the volume on the receiver does fix itr. 90% of the time this does not happen but then out of no where it's all distorted. I confirmed it's the speaker by swapping in and out another one while it was happening. I should also mention I recently purchased a new receiver and it's still doing it. Any solutions or is it slowly going?
