I am preparing my walls for the mounting of some RS-25s, that I have yet to purchase. I want the RS-25s because of their size and also they match my RF 25s. I am going to hang them using the screw method. Here is my question. How far down is the keyhole for the screw from the top of the speaker? Also, are there two keyholes or just one? Are the speaker wire terminals centered on the back of the speaker. I suppose it would help to buy them first and do exact measurements but wife is ready to paint now. I need to get everything patched up. I don't really need exact measurements, just close. I know this is asking a lot but if someone has one they could post a picture of, that would be very helpful. Thanks
