@Jeffrey S. Albaugh
Thanks for the reply. Most of the information is in the original post. I'm doing 5.1 driven by a Yamaha RX-V679BL receiver. I'm not sure if it has support for multiple subs in the same zone. I live in southern California. What considerations does geographical location require?
As for running the wires, that's not a problem at all. The attic is quite extensive and there is an enormous amount of space above that room. Walls are drywall with studs. Occasional, random horizontal block is the only thing standing in my way.
If I went with in-wall speakers, I was thinking about placing them in a row close to the top of the wall. Is that advisable? I'd get something with white mesh, if possible, and frame them to look pretty if they did not already come with a frame.
I think the biggest thing that I need to know now is what in-wall speakers to use. What offers comparable or better performance at a similar or lower price point as the cambridge minx speakers?
I looked at the SVS subwoofers. At 3 and 4 times the price of the BIC subs, I'd definitely expect them to be better. Again, I think that BIC is the best bang for the buck. Going higher than that requires commitment and a much larger budget. Are you referring to these subs wrt the HSU brand?:

Thanks again for all of your help.
