A friend of mine used in-ceiling speakers located a couple feet behind the main seating and it worked really well. Being in the ceiling produced a nice, distant, diffused sound that blended very well and produced a very enveloping and immersive experience. It was so good (and so unobtrusive) that when I do my HT I’m gonna set up my rear speakers this way. Hope this helps, and best of luck.
Surround Theater Speakers Suggestions
I am currently using a B&W CM5 and one of my speakers blew and looking to replace the pair.
Are in-wall surround speakers good? Or should I go for B&W bookshelf type speakers.
