you guys spend a lot on HT

hi guys, any of you try the 5.1.2 Dolby Atmos setup with only 5 speakers + 1 sub-woofer? which mean the front speakers (both left and right) got another speaker facing upward to fire the sound toward ceiling...any comment for this setup? my house living room is not big, wish to change my current Yamaha RX-V671 to another new model of receiver with capability to support 4K HDR + Dolby Atmos

Up firing atmos is totally useless

any other option available other than mouth the speaking on ceiling?

i heard if install speaker either on ceiling or wall, then have to configure the speaker as "Height speaker" instead of "Atmos speaker" (configure in receiver)...if this is the case, it still consider as Dolby Atmos? it become like 7.1...

There is no easy way to do this unfortunately. Height is different from atmos as you already the position of the speaker is different.

u can try out some upfiring speaker for atmos.. its impossible but difficult. Go to CMY at sunway look for steve. Seek for his advice.. The last show room he had in 1U is using upfiring atmost speaker that reflect from ceiling.

it you plan to do it at home of cos you need to check hows ur ceiling being designed and if the reflection can be done easily without much distortion..same concept applies for sound bar.. complicated engineering..

the best is to do direct mount on ceiling.

atmos do not have height speaker (mount on wall not ceiling on top of your head) but dts x they have height speakers

sad thing is I stay in penang....currently i have 5.1 speaker (plan to upgrade but stick with 5.1 + 2 atmos enable speakers due to space limitation), if i want to enable Dolby Atmos (1 pair), where is the correct placement for the speaker ?

FYI, this is my current speaker placement: center, main L/R, subwoofer, surround back L/R

i have ceiling fan on top,will this consider distortion if using upfiring atmos speaker?

thanks again.

if you want to do upfiring then you need to place it on top of your front speaker (LR) for 5.1.2 setup.

If you want to place it on the ceiling you can place it on ceiling of where your king seat is.


could be an distortion if reflection point on the coverage of the ceiling fan blade.. need to do trial and error..

there's 1 more thing you can do if you r desperated.. get an extension up and hold ur ceiling speaker on the arm.. sort like a lamp extension..

btw which avr r u using? does it support for atmos? have u check on it?

1st of all, thanks alot for all the detail info , can you explain a little bit on "extension up and hold ur ceiling speaker on the arm.. sort like a lamp extension" ?

Im using the old receiver (Yamaha RX-V671) and plan to upgrade to Atmos support receiver soon currently looking at below model:
Onkyo Tx-NR686, Denon X1600H, Yamaha RX-V685

something like this


just some idea

i dont think x1600h is atmos compatible.. even x2600h would required external amp for this purpose.

you might wanna increase ur budget to get at least x3500h if you prefer denon.

Also consider you are increasing your setup from 5.1 to 5.1.2 extra amplication will be required from the avr. If you upgrade to something similar like your existing you wont be playing at the same volume. Performance will drop.

i m using x2000 myself and yet to upgrade considering the cost vs the performance of having 2 extra speaker on the ceiling

hm...according to the Denon, X1600H support Atmos, even with "Dolby Atmos Height Virtualization Technology" (below link)

by the way, i though receiver output power is equally for all channel (except the subwoofer) example 90 W per channel (8 ohms), so for the case if i upgrade similar like what im having now (from Yamaha 671 to 685), it shouldn't have any issue for the performance, right?

Any sharp soundbar user? The bluetooth is not synchronising no matter how I try - sorry if not suppose to ask here

The easiest way not to cut holes in your ceiling is to just do on-walls, high up. It's about as easy as it gets, drill 4 holes - put a bracket, install your speaker - pull your wire.

Example:



It's leagues better than the silly upfiring method, doesn't cost too much to do and can be done in an hour or so. Clean up is also minimal.

you can check the spec sheet. its marked as -/- for dobly atmos/dts:x

It says Height Virtualization.. its using height channel to virtualized.. better to double check and understand this. I got this from the review
The 7.2 channels can be appropriated in a 5.2.2 configuration for Dolby Atmos and DTS:X formats, but for those without the extra height speakers, there is DTS Virtual:X onboard for the up-mixing of DTS soundtracks – to give the sense of height. Dolby Atmos Height Virtualization Technology, which essentially attempts to do the same with Dolby soundtracks, is promised via a future firmware update.

Its like 4k resolution but upscale from FullHD. Its not true 4k.



by right yes. but these avr doesnt work this way. Read the statement from the page.
Upgrade your home theater with the Denon AVR-X1600H. With 80W per channel (8 ohms, 20Hz-20kHz, .08%, 2 ch driven), this performance-tuned Denon AV receiver provides a truly immersive 3D audio experience. Supports Dolby Atmos®, Dolby Atmos Height Virtualization Technology, DTS:X™ and DTS Virtual:X. Watch your TV or projector video content with the best possible picture thanks to the latest 4K video technologies like Dolby Vision™, HDR10 and HLG.
80W per channel 2 ch driven (8 ohms). If you only have 2 channel u can get the throughput of 80w per channel. If you connect 5 channel then you will not get 80W maybe 60W... if you connect 7 channel maybe you get 40W only. But of course Denon work smarter by giving power to demanding channel as priority. But in short, your power is being divided out.

The best for Atmos is at least X3500 for denon. At least more headroom for your 5.1.2/7.1.

This is important if you r running your setup in a large area/room. If you have small room then you have no issue. If you already running 70db with your 5.1 setup you may need to run 80db when u setup for 7.1/5.1.2

nice setup bro..

thank you

thank you, by the way, if compare Denon and Yamaha, which one you prefer for movie?

i think there are some mistake on this "spec sheet", i read through the user manual for Denon 1600, it support Atmos, it even show the speaker configuration and placement strategy to enable the Dolby Atmos in the manual

i m a denon guy thats why u see i compare denon only..

Immerse yourself in multi-dimensional audio with Dolby Atmos. Set up Dolby Atmos with a 5.2.2 surround sound speaker system using Dolby Atmos elevation speakers, or dedicated overhead speakers, for the ultimate home theater experience. Dolby Atmos Height Virtualization provides immersive audio without height channels, creating virtual height effects in a 7.2, 5.2 or 2.2 speaker arrangement.

yea i could be wrong.. it says 5.2.2. So should not be any prob.

That's not my setup, just an example that I found for the Prime Elevations.


It doesn't really... work that way? The speakers dictates how a movie (or anything really) sounds like for the vast majority of what you hear. The receiver (and amp) doesn't quite "add" or "alter" that sound quality. It's a bit more complex than that. Different room EQ (in this example Audyssey vs YPAO for Denon vs Yamaha) will work differently in different rooms, which is one of the most important things in home audio. So just with that alone (along with several other variables like the amp section in receivers) already discredit a comparison between receivers.

So to just compare Denon vs Yamaha, which is better for movie... you can't compare it that way in a apples-vs-apples comparison.

You choose a receiver based on the features you want and how deep your pockets are. Not how they "sound".
