Re: Luna as Surrounds mounted horizontally?
Bumping to get some ideas. Here is m thoughts right now. Sierra RAAL Towners and Horizon front stage. 2 pair of Luna monitors mounts horizontally (space issues) for sides/rears and Sierra 2EX as front heights since consensus is the top speak elevations (bounce) speakers do not doe much, although in my room I am the ideal Dolby candidate for bounce speakers, 8 foot ceiling about 14-15 feet from speakers. My other options, far less disabler is for surrounds go with Emotiva A2+ as they have a ribbon tweeter and I would hope they would sonically be a close match, while not perfect.
Since my sides and rears are higher than ideal horizontal would all the wide dispersion to encompass my seating, the concern is that now wide vertical dispersion bounces off the ceiling as well. I would angle them down toward ear level.
Denon X7200WA, Monolith 9X, Dual PSA V1800 subs, Klipsch RP-280F/RS-62ii Front stage, RS-35/25 sides/rears and RP-140SA Elevations.
