I really wish I knew on the ceiling. I love it but to be honest it's original to the house and built in 1955. Walls and ceiling are plaster so I'm not sure how it was accomplished. Thanks for the input! Cheers.My understanding of the debate between bookshelf vs. tower speakers is that towers have two main advantages over bookshelves: low frequency reproduction and output level. A tower speaker, generally speaking, does better at sub-80hz frequencies than a bookshelf, so if you didn't have a subwoofer, I'd say go tower any day.
With a subwoofer, in most setups, the sub is playing everything below 80hz anyway, so that advantage doesn't apply in your case.
A tower speaker, generally speaking, can play louder and fill a larger room than can a bookshelf speaker. But since the portion of your room that I can see doesn't look that big, you will probably be perfectly happy with the R3.
Some people argue that a tower can produce cleaner sound because it has more drivers sharing the load. All things being equal, they are probably right. But IMHO nice speakers can make up a lot of that difference, and the R3 has 3 drivers, making that point mostly moot in this case.
I don't have any personal experience with the R series, and my two front speakers are Q750's, so I'm mostly repeating what I've read and not speaking from experience.
Off topic, but, I like the ceiling panels you have in that room. I may have to steal that idea. Is that just custom-cut plywood nailed to the ceiling and painted?
