lol. had to google that
possible. but is there really much coming from above in real life? is there a way to extract height channels from atmos material so I can get an idea?
Currently running a 9.2.2 in the living room area with 9 KEF LS50 which is smaller than the dedicated space I am looking to do.Perhaps a 7.2/4.4 could be enough in such a space.
FYI I added a comparison of KEF's own measurements against mine (they were kind enough to create the overlay):
Maybe. I don't know of any underlying research validating it. Regardless, KEF has that implemented a mild version of it if you look closely at the frequency response.Amir, I’m curious why your comments for the output of an upfiring height speaker are based on its performance as a main speaker. Wouldn’t it be better to draw the Dolby target curve on your chart above and discuss deviations from target?

I sourced the above from comment #195.
I also have another suggestion for a useful performance measure for upfiring Atmos speakers. The Precedence Effect dictates that at, a certain DI, the apparent sound source will move from the ceiling to the speaker box itself (a weakness of upfiring height speakers that ceiling-mounted height speakers don’t have). In fact, the direct arrival sound does not even need to match the ceiling reflected sound SPL before the Precedent Effect takes over: for the given amount of delayed reflection, there is a lower SPL for off-axis direct sound where precedence will dictate that we hear the apparent source as the direct sound. So, a useful performance measure would be the frequency below which it ceases to act as a height speaker, ie it ceases to function for its intended purpose.
It can also be used as an on wall surround speaker, so direct sound does matterI guess they do not care enough and went with simulation because they know noone will ever notice anyway due to the application of an up firing speaker which will only play reflected ambient sounds..
But I may be wrong. And cynical..
Being dual purpose requires either compromise (“jack of all trades, master of none”), or sacrifice of one purpose for the other.If you look at Kef’s website these speakers are sold as: “The R8 Meta can serve as a surround or rear speaker with the integrated wall mount feature, or be placed upon another speaker for Dolby Atmos height to bounce sound off the ceiling”
I have a feeling that a lot of customers buying these will use them wall mounted.
Yep. This is why I use 9.x.7 setup with Center Height. All with standard bookshelves speakers mounted from the ceiling. 2 holes in the ceiling for each mount.
Some months ago there was a very heated up debate between HT youtubers. On the one hand, the Audioholics guys argued that in ceiling speakers are the right way to go while Joe´n Tell and TechnoDad argued that height speakers, as long as the angles were well aimed, was equally good with the advantage of the flexibility for Auro and DTS.
From your perspective, you seem to align with the idea that a height setup, not just strictly in ceiling, can be perfectly functional. I have only tried bookshelves on a very tall shelf angled down and it worked quite well, but you definetly have the advantage of having tested both methods.
They could have a switch between two crossovers, I suppose. But the official Dolby demos with bouncers seem to use KEF R-Series speakers, so maybe there's less than meets the eye with compensation curve.Being dual purpose requires either compromise (“jack of all trades, master of none”), or sacrifice of one purpose for the other.
I would much rather see a speaker made for one specific purpose.
I’m confused what format supports that.
Auro supports 5 height + VOG
Atmos has even numbers (no center)
“The R8 Meta can serve as a surround or rear speaker with the integrated wall mount feature, or be placed upon another speaker for Dolby Atmos height to bounce sound off the ceiling”
What does this W looking drop mean? That must not be very good!FYI I added a comparison of KEF's own measurements against mine (they were kind enough to create the overlay):
As I noted in the review, the agreement between the two is incredibly good! The only deviation is bass where their anechoic chamber is too small to be accurate there.
