KEF R8 Meta Dolby Atmos Speaker Review

[napfkuchen]

Has anyone compared the performance of Q50a and R8 Meta when used as up-firing Atmos modules? I haven't found any direct comparisons in this thread yet.

Using a speaker in up-firing placement will give bad results, does not matter which model.

Some processors (Stormaudio/Trinnov, maybe others) can allow you to send bass below a frequency to the nearest speaker of your choosing. For example if you had a top middle speaker that you wante to crossover at 150hz, you could send below 150hz to a surround speaker and then below 80hz (or whatever your crossover setting is on your surround) would get sent to subs.

This is an awesome function! Now I know why processors like Stormaudio is so expensive, thanks!

But on a modest budget using LX805 (with Dirac Live Bass Control), any good ways to get R8 Meta integrated?

Interesting that despite the "bad results", many manufacturers are advertising the "up-firing" as a "feature," why is this happening and no additinal backlash?

But realistically speaking: Shouldn't someone who can afford a 15.000-30.000€ AVP also be capable of getting better speakers in the first place?

It's not like there aren't any alternatives of similar size that extent down to at least 80Hz

That's a very good point.

Since I really like the R7 Meta (fits my room too), but R8 Meta doesn't seem like a good match (due to high crossover) for my AVR, maybe it's not too much of an issue to match up with other brands' Atmos speakers that extend to or below 80Hz? After all, my Dirac Live AVR should be able to address the timber mismatch among different brands right?

Manufacturers also advertise soundbars with 9 channels which are supposed to work with even more reflection trickery ... Money.

I don't think there would be a huge difference if the Atmos speakers are from a different brand as long as they measure well.
If ceiling mounting is an option, the Kef LS50 Meta apparently can be hung from the ceiling because they have screwholes and there are a few aftermarket mounts for those.

Upfiring works better than "virtual heights" or no heights especially if they're properly done with Atmos HRTF filters. Some "presence" speakers are angled but do not implement the filters as recommended by Dolby.

Random upfiring is less predictable than ceiling mounted Atmos speakers. Also, individuals can have different HRTF's so it doesn't work for everyone -- but the patent shows that the the chosen target should work reasonably for most people.

Which ones?

Are these r8 metas still good to get atmos as I have the r series Kef speakers. Do they add a lot more and do they sound good. ?

Thanks

I'm trying to do just that, however I'm not there yet. Happy to share some thoughts a tad later.

My seating position is near the back wall. I also have a small room, and would be difficult to mount larger bookshelves as rears due to the existing furniture.

I also don't think that putting them on the walls pointing down is a great idea for rears, as they should be at the same level as the mains, to have a coherent bed layer.
Dolby specs say that the height of the rears should be a maximum of 1.25x of the height of the mains.

So i'll try to mount them as rears, rotated in the corners, like in the photo, thanks to the coaxial driver having almost equal horizontal and vertical dispersion.
This way they will point into the listening position and be at ear level. I'm also hoping this will minimize acoustic reflections from the back wall due to the angle of the driver.

Crossing fingers

Did you try that after all?
I am also considering them for surrounds, would be a great match alongside a center R2 Meta or R6 Meta i think.

Hi All

I Have Bought Some Kef Atmos Meta Speakers and have put them on top of the front speakers and wired them in. I noticed there is a couple of options in the amp to tell the amp were placed, and are

Front Hight - The front presence speakers are installed on the front wall
Overhead - The front presence speakers are installed to the ceiling
Dolby Enabled SP - The Dolby enabled speakers are used as the front presence speakers

I Have Selected the Dolby Enabled SP is this right? as in the image on the screen these a placed on the speakers and front hights are above on the wall.

i am wondering what each selection would the amp do to these sounds to the speakers as i would of thought they would be just the same or am i wrong? have i picked the wrong option for Atmos setup?

I did a recalibration and this time did a 3-point setup on sofa left side, middle, right side about 2m spread as i only did a single centre one when i first set the amp up.

Also noticed the amp has put the cross over to 100hz but not sure if i read that its best to put these at 150hz? any thoughts on that.

thanks
