Hi everybody,
I've searched four many hours to find some conclusive answers, found loads of information, but could't reach a conclusion about in ceiling surrounds.
I use multichannel for watching movies and playing videogames. I listen to music in stereo (so I don't care for multichannel music).
I currently have a 7.1 home system with side and rear surrounds in the ceiling (straight sounding), but I`m not satisfied with the sound clearly coming from above. I have (some) side walls to the left and right and no wall in the back of the Home Theater.
So, which kind of ceiling speaker would result in the best surround effect (diffuse or side directional, not directional from above):
- For the side surrounds (considering I have some wall for reflection): monopoles aimed at the ears, monopoles aimed at the walls, bipoles or dipoles?
- Rear surrounds (No wall for reflections): monopoles aimed at the ears, bipoles, dipoles (or no rear surround)?
Thank you for all knowledge shared. I've learned a lot here.

Fred

have you investigated the Atlantic Technology or Triad speaker lines? Check out the speaker forum.

Yes. Athlantic Technology TLC models have a Monopole/Dipole switch, but that doesn't fully answers the question. Def Tech uses Bipole for Ceilings (against Dipoles), and I don't know if they work better aiming at the walls or the ears or if they work at all without any reflecting wall (the case with my surround back speakers).
Thanks

CREATOR: gd-jpeg v1.0 (using IJG JPEG v80), quality = 80

triad has some models I have installed in the ceilings of larger rooms that had no rear wall nearby to reflect much sound. The bronze surrounds are dipoles, there is a definitive right and left, front and back to the speaker placement. The omni's are monopoles, which when properly placed, will work very well.

Thank you Weaselfest.
Is there a preferred type of speaker for each application, i.e. dipoles for side surround and monopoles for back surrounds?
Tks once more

yep, dipoles on the sides, monopoles to the rear. spacing will depend on ceiling height and seating arrangement. Here's the dolby and THX speaker placement guidelines to get you started.....assuming you haven't already seen these.
