I'm building a house and had a local company wire it for sound and in 1 room there is supposed to be a connector meant for a subwoofer. All the other places for speakers have just standard wire hanging through the ceiling but for this subwoofer, they already put a plate on it and the connector they used is one of those jacks just like a cable outlet. Is the wire used for a cable outlet the same as speaker wire? I'm trying to determine if they could have made a mistake with the connector or if it means they put the wrong type wire in the wrong place. Any ideas?
