Try to visualize this...Tonight my 10yr old son and I got a little brave and decided to mount the RC-64 in the top part of the cabinet above the screen. The room is 10' high and the cabinets stretch from the floor to the ceiling. I currently do not own a ladder so I brought in our bar stools. Jacob and I stood on the barstools and I hoisted him into the cabinet from the open sides to unscrew the two screws that are temporarily holding the top center panel cover in place. Once removed, I moved 4 barstools in front of the cabinets. Jacob said he was nervous about having to pick up a 62 lb speaker. I told him "If I didn't think you could do it, I wouldn't have put you up there. I trust you son." What a cool teachable moment for my son to hear his Dad say I trust you with a $600 speaker and I have confidence that you can help Dad move this speaker without damaging it.
I placed a towel inside the cabinet for the RC-64 to lay on since the cabinet is made of wood and would scratch the bottom of the speaker. I placed a pillow on two barstools and laid the RC-64 on the pillow. Standing on the other two barstools, I lifted the RC-64 and gently slid it into place in the upper cabinet. My son helped me to gently guide and slide it into position. Once positioned, I had him hook up the speaker and I lifted the rear of the speaker while he screwed in the angle adjustment. Jacob did an amazing job. He was nervous about being inside the cabinet and being that high off the ground but he trusted his dad because he knew that I wouldn't put him in a situation where he could get hurt.
To my surprise, the angle was almost dead on with my primary listening position. I really didn't think it was going to be enough angle but it was. My wife was in bed so we didn't get to test it out very much until she came in and asked to turn it down. I'm really hoping it isn't too distracting with the center being above the screen. Probably no one will notice, but I notice because I know where it's there. We'll see if it is distracting once I get a chance to play a movie at a good volume.
Now that I see how the cabinet was made, it would have been PERFECT to have an acoustic transparent screen and have mounted the RC-64 directly behind the screen. Arggg. Too late now. LOL.
When I ran the YPAO in the yamaha, it said not to use Back Surrounds if I did not have Side Surrounds (since I currently have a 5.1 setup) so I switched the RB-35's to the "Surrounds" and wow, what a diffference. To be honest, after mounting them, I totally was not satisfied with the surround effects. I felt I was not really hearing them. Granted, when I turned them off, I did notice them not being there and I realize surround speakers should not bring attention to themselves but I really wasn't hearing much from them during big surround scenes.
In the short, semi-loud scene we watched, I totally heard a difference. Guess it helps when you have the speakers connected to the correct terminals on the receiver.
Here's a shot of the speaker in place.
