Just a little back ground about myself. I have been into stereo, since the early 70,s when my father was stationed in Japan. My first stereo was the Kenwood Model Eleven. I took the TV I own and disconnected the speaker and wired the output to my stereo. The sound may have been mono but what the heck, it was playing through two speakers. My next purchase was a Marantz Quadraphonic system, which was the old four-channel sound - and look what they have now done with the surround sound receiver or processor. Multi-channel is back again. My goals have been to fool around with the sound and make it sound like the sound is coming from a location that it isn’t (phantom image or sound). I play a lot of my music in stereo because that’s how I’ve trained my hearing. I will always put on a CD or LP and ask that person, which speakers are playing and they will point to the center and the surround speakers. Then instruct them to walk around the room and tell me which speakers are playing and they will always freak out when they realize it is only my left and right (main) speakers. Also did this to my surround speakers when it was only ProLogic and eventually 5.1. Again would ask the person where the surround sound was coming from and they would always point to the rear speakers, which I proceeded to lift up and show them that they weren’t even connected (dummy speakers in the rear). I would use Jurassic Park when it first came out in laser disc as my reference disk. I would go to the chapter were the jeep would drive over you. People would look up at my ceiling to see if there was a speaker. Mind you this was software recorded on laser disk in Dolby ProLogic. Each individual will have a different taste as far as what they like – mine is sound quality. When movies become available to the public I brought into the Video Tape, CED and laser disk. In fact my laser disk collection is so large that I ended up buying five extra laser disk players for backup or spare parts. Before ProLogic was popular the tapes and laser discs would say stereo on their jackets, but these had the surround channel embedded in them, since the ProLogic decoder was a matrix system, which brings me to my point that I can see how the height channel can play into this because it is matrixed. Correct me if I’m wrong. Ever since they came out with the rear center channel (6.1 or 7.1) I felt as though the sound would jump to the back speaker from the surrounds, in certain movies. Debated whether to add a height channel, which is a speaker or speakers above the sweet spot. Purchased the Smart Device CS-3X processor sometime back and was doing research to make sure that this would not be a mistake, since I was hesitant in cutting a hole in my ceiling. Asked the question: if anyone had installed the height channel on this forum and there was one person who helped me greatly. Wanted to add this channel because was dissatisfied over how the sound would jump in some instances from the surround speakers when mounted on the side walls to the rear center speaker when a disk was encoded with either the EX or ES (6.1), instead of having a smooth transition (I always called this a hole in the sound). Finally took the plunge and installed a pair of speakers over the sweet spot. Since installing the overhead channel the room has taken on a whole new dimension as far as sound. At times it seems like there are no walls or how would you describe it, it seems like the room is much larger (spacious). The sound transitions smoothly to the rear center now. And yes, it sounds like things are going over your head when the need arises. I have listened to this setup for over two months playing the movies once again that sounded like the sound jump from the surround speakers to the rear speaker. Also hooked up the Xbox to my system and played a few games; in fact, liked it so much that I ended up having to buy another Xbox, after using my daughter’s. All I can say is playing games on this setup takes it to another level. Well, our neighbor across the street had never seen a movie on our setup, so we invited them over. My family and I will normally let the guests sit in the front row so we can watch their reactions. They ended up picking “Hidalgo. They were impressed with the picture, but when the locomotive train went over, that is when the WOW started and the laughing and “this is the best sound we have ever heard, it’s like your there”. And the best part was when the husband said at the end of the movie “this setup blows the movie theaters away”. This was the first time that any one has heard this setup with the height channel. When I hear comments as the one above, that is when I feel all my work has paid off, even though I have more to do. What I also like about this hobby is that it can be shared with others. So now I have a smooth transition to my rear center speaker plus the added benefit of things flying overhead. By the way this does not work with all movies, but when it does it is very impressive. Would like to thank Wes for all his help and saying go for it. You just have to hear this setup or experience it before you can say whether it will work or not for you.
