Atmos speaker design advice

[sleeper0404]

Hello all,
I have been looking into maybe wiring my living room for atmos. I can't seem to figure out if ceiling mounted spekaers or upward firing speaker on top of front towers would be better... does anyone have any good suggestions on what would be best? also if anyone knows of some diy designs too show me that would be great, I can't seem to find any. right now I have a statement 2 setup

I'm currently doing an Atmos setup.

-suggested configuration seems to be above/(ceiling) your listening position (for those height channels) but further left and right of your front left and right speakers (respectively). The 9.2 system has an added set of speakers a little forward of your listening position (also ceiling, and also "wider" than your front speakers).

-if I was doing a setup with that far of a listening distance from the front speakers for a 7.2 system (as represented in all of their diagrams), THEN I would probably move those height/(ceiling) speakers a little bit further in front of the listening position (..perhaps about half-way between the first and second set as represented in the 9.2 system). One thing I would absolutely do is make sure those height channels AND the rear channels are much wider than your front channels.

I think your missing the second images on your links. Dolby recommends the height channels be in line with the fronts.

When you click the link, pick a layout. The first image would be the typical standard layout, second image is the added height speakers.

Definitely go with in-ceiling, if you can't get the rear heights the recommended angle behind you, stick with a .2 setup.

Cheap, low profile and good soundquality for what it is.

Yup, my bad ops: - had to use a different browser to get the pic. displaying the side-arrow for the second pic..


I'd still do it the way I was suggesting though for a narrow front channel grouping (with ceiling height channel further off to the sides, along with presumably rear ceiling channels).

In theaters the placement has added side channels near the front channels (on the side walls), front channels that span most of the width of the theater (because the screen spans most of the width), and those ceiling height channels are substantively left and right of center-row listeners.

(..in my installation both the ceiling height and ceiling surrounds will be "in-line" with the front Left and front Right speakers - but that's because my front Left and Right are almost 14 feet apart with a 14 foot wide screen, and we "listeners/viewers" are centered to the screen and will still be substantially away from either side.)

Thanks for all the replies. does anyone have any suggestions of a good store bought in ceiling speaker or atmos setup or know of any diy in wall setups?

Partsexpress has several listings at reasonable prices:

-do NOT select a 70V speaker.

Here are the in-walls:

Most HT Receivers do NOT have adequate power supplies when using all their amplifiers. For this reason I'd look to 8 ohm loudspeakers (to draw less current).

Ex.

Left/Center/Right in a vertical configuration on-wall:

If you have a receiver that you do not think has enough power when driving all channel is to add a high quality stereo amp and use that for your mains while using the receiver for the rest of the channels.

thanks for the responses. I think I may try out 4 of the dayton part 300-430 speakers. I'll be going for a 5.1.4 setup I mostly am interested in trying out atmos. would you guys think it would work out okay if I did 2 in ceiling angled towards listening position then 2 behind angled toward listening position with the 2 surround speakers mounted on back wall close to the ceiling?
