Re: Atmos height speakers for a system that uses RAAL tweeters.
I'd recommend buying designs with a pivoting tweeter...it should help in positioning sound onto desired locations or seating area. I've been extremely happy with my MA inwalls...moving from a traditional mounted monitor and bracket. I'd also consider getting enclosed speaker with minimum 8" mids...you'll get a little more fuller sound since these type of speakers are generally void of reproducing or excelling at mid bass frequencies. Otherwise they are easy to install except for doing a clean install through ceiling etc.
