So far I ordered
Kef ci200rr thx ultra 2 for top middle/top fronts
Klipsch cdt:5800 for rear height/ or in ceiling surround back
Klipsch 6504 thx ultra for front left/right
Klipsch S 7800 thx ultra 2 for surrounds
My question is where did you place your kefs in comparison to where you main seating position? Where they directly overhead, or slightly behind or slightly in front....what do you think of 7.1.2 in comparison to 5.1.4?
Hi, ultraflexed. Thanks so much for reading and best of luck with your new Atmos cinema. It's a wonderful upgrade for home cinema and audio enthusiasts!
For my review, I used a 7.1.4 Dolby Atmos configuration similar to the one pictured at the bottom of this page: http://www.dolby.com/us/en/guide/dol...-4-setups.html
IE, I added four in-ceiling speakers to a traditional 7.1 speaker system. One pair of Ci200RR-THX speakers was placed slightly ahead of the main listening position, while the second was behind main listening position about halfway between that position and back-surround channels. Either way, that Dolby guide is pretty good way to approach 7.1.4, which is my favorite Dolby Atmos configuration thus far.
Regarding 5.1.4 vs. 7.1.2, I think that's going to depend on each listener. I personally love my side surrounds, which is why I made the push the 7.1.4.
If 7.1.4 is not an option, 7.1.2 and 5.1.4 are going to each have their benefits and drawbacks. The 5.1.4 system is going to have more accuracy for panning Atmos and DTS:X height objects, while a 7.1.2 system is going to be better with ear-level sound cues. I'm currently reviewing the Klipsch Reference Premiere Dolby Atmos speakers in a 5.1.2 configuration, which taught me two things: 1) two overhead speakers can do a great job with Atmos, but I prefer four overhead speakers for maximum impact. 2) If you only have 5 ear-leavel speakers, I prefer to place the two rear surrounds on the sides and behind the listening position by about 45 degrees (ala this image from Onkyo: http://res.cloudinary.com/hrscywv4p/...27ykxkqd4j.jpg
). Some 5.1.4 systems, particularly those with Dolby Atmos up-firing speakers, place the rear channels behind the listeners (ala the second image here: https://www.kefdirect.com/index.php/...dule-pair.html
), but -- for me -- this creates a hole in the sides.
Looking closer at your comment, it appears as though you might not have a back wall in which to place speakers since you need to go in-cieling for "back surround" OR "rear height". If that's correct, maybe the compromise is to wire your ceiling with one pair in front of the listener, and one pair behind, then play with your setup, toggling those CDT 5800s between "back surround" and "rear height" to see what you prefer. I would bet, in that configuration, you'd want those rear height speakers to be "back surround" channels rather than height because they would be more active. Then you could KEFs as "front height channels" rather than "middle" (directly over the listening position). And, if you're ever able to add true ear-level "back surrounds", the others could easily become rear height channels.
Regardless, please make sure to consult with your installer (or other forum members) because they will likely know more than me about your specific environment and needs. Good luck!
