Hi Michael,
Thank you for taking the time. I've attached some pictures and measurements. The first picture is of the back wall (the wall behind my intended listening position) where you see the lower ceiling; the second is of the front wall (where I intend to place my gear and speakers). As you may notice, both sides have a 4-feet tall, 7-inch wide ledge thus making even these walls an "uneven" vertical surface.
I anticipate placing the speakers about 6 feet from the front wall (employing a bit of the 1/3 Rule) with a yet undetermined listening position (probably 5-6 feet from speakers). Having said that, I'm open to reversing the location of the speakers and listening position such that the speakers are under the lower ceiling instead of the higher ceiling, if you think that would sound better. In either case, I'll cover the windows with thick curtains.
This used to be a 10'x9'x9' room (almost a cube) that I extended out to 17'. As you can see, I had no choice but to extend out to a space that had a lower ceiling (due to ducts).
So my questions are:
1) Should I place CornerTunes on all six ceiling corners?
2) Should I place an EchoTune at a side midseam relative to each ceiling height or just one at the midpoint of the room (and thus ignoring the fact that there are two ceiling heights)?
3) How should I use TuneStrips in this room? I had previously vertically attached them in the corners below the CornerTunes, but the ledges on the front and back walls make it difficult locate properly.
4) Does it matter whether the speakers are placed under the taller or shorter ceiling?
I currently have the TunePak, but would be willing to acquire additional pieces, if you think they would make a difference in my room.
thanks,
