A friend is building out a loft and wants to re-use some Jamo in-wall speakers he found in the loft. We connected them and they sound reasonably good (I'm not a fan of in-wall speakers generally, but we all compromise somewhere and since he has five of them and they sound pretty good, it makes sense to use them).
In the image below, you'll see that the TV is going on the West wall (red line on the wall). The LR and C will accompany the TV. The question is what to do with the rears. I'm attaching photos of the speakers in case that's relevant.
My friend originally wanted to put the rears above the couches (ceiling mounted). The couches are a bit off center - that's another compromise because the dining room makes it impossible to center the couches. I looked at the space today and suggested that he consider putting them in the East wall (opposite the TV wall). They would be some distance from the seating area, but he can adjust the delays to compensate for that and he would have them ear level in that position, as opposed to ceiling heigh over the couches (the ceilings are 12 foot tall). The ceiling is a drop ceiling, so he probably would need to build out a cabinet/box for the speakers if he installs them there, so that they're not hanging in open air.
As you can see, it's a big, open space. What do you think? Better to install in the ceiling (surrounds) or in the East wall opposite the TV?
Many thanks in advance for your advice.
