Melhor adição de Dolby Atmos em alto-falantes para home theater – quais escolher e como eles funcionam?
Tendo recentemente adquirido um Denon AVR-x4500h 9.2 (leia nossa análise do Denon 4500h aqui) abriu as portas para a adição de alto-falantes Dolby Atmos. O Dolby Atmos é usado nos cinemas há muito tempo, então estou muito ansioso para configurá-lo em casa. Estes são chamados de alto-falantes de altura ou alto-falantes de disparo ascendente.
Especialmente no inverno, faz muito sentido ter um ótimo home theater interno configurado para curtir com sua família e amigos. Os alto-falantes Dolby Atmos apenas aprimoram sua experiência de assistir a filmes.
Também atualizei esta lista para incluir não apenas alto-falantes Dolby Atmos de altura, mas também teto, chão e temos nosso artigo sobre barras de som Dolby Atmos que destaca as barras de som que suportam Atmos.
Aqui está tudo o que você precisa saber.
Apenas me mostre a lista de alto-falantes atmos.

O que são alto-falantes de altura Dolby Atmos?
Esses alto-falantes de altura Atmos ou módulos Atmos, como algumas pessoas os chamam, podem ser adicionados a um sistema existente e geralmente são colocados em cima de seus alto-falantes de piso existentes. Se você não tiver alto-falantes de chão, poderá fixá-los na parede.
É possível comprar alto-falantes Dolby Atmos com módulos de altura embutidos, mas para a maioria de nós, já temos uma configuração que só precisamos adicionar os alto-falantes de altura Atmos também.
Espero que minha jornada por esse processo seja útil para você, então continue lendo!

Os alto-falantes Dolby Atmos valem a pena?
A primeira coisa a dizer é que a maioria dos alto-falantes Dolby Atmos não foi muito atualizada desde que todos inundaram o mercado por volta de 2015-2016. Algumas unidades mais recentes foram lançadas ou atualizadas (como o ELAC Debut 2.0 A4.2), mas principalmente elas mantiveram o mesmo intervalo. Esta lista inclui a maioria dos alto-falantes atmos disponíveis em 2021, mesmo que tenham sido produzidos antes deste ano.
Também falei diretamente sobre essa pergunta neste post.
Uma das reclamações dos fãs de home theater é que por muito tempo havia opções limitadas para títulos de filmes em Dolby. Felizmente, isso está mudando com a maioria dos novos blockbusters sendo lançados com trilhas sonoras Atmos.
Há sempre o medo de que você esteja pulando em uma tecnologia moribunda, mas para todos os efeitos, parece que o Atmos estará conosco por um longo tempo. E se o Atmos passar, ainda há o formato DTS:X e o Auro-3D®, que também utilizará os mesmos alto-falantes em que você investiu.
Esta lista de trilhas sonoras Dolby Atmos do IMDB (link abaixo) é encorajadora o suficiente para fazer você sentir que investir em um conjunto de alto-falantes de altura atmos é uma ótima ideia.
https://www.imdb.com/search/title/?sound_mixes=dolby_atmos
Então, os alto-falantes Dolby Atmos valem a pena? É uma coisa pessoal, mas acho que eles adicionam outra dimensão ao Home Theater e trilhas sonoras de filmes/áudio. Para o ouvinte mais exigente, é um pequeno investimento que permite aumentar o nível de suas experiências de filmes caseiros e música HiFi (se tiver sido mixada para Atmos como esses). E você leva a sério o som e é por isso que você está aqui.
O que significam todos os números? 5.1.? e 7.2.? etc
Ao analisar os números de um sistema de home theater multicanal, é muito fácil entender como ele funciona. A configuração do Atmos significa que eles adicionam mais alguns números ao final. Isso dependerá do que seu amplificador de home theater pode suportar.
Isso geralmente se parece com isso:
Um sistema 5.1 comum incluiria 5 alto-falantes principais.
- 2 alto-falantes frontais
- 1 alto-falante central
- 2 alto-falantes de som surround
Isso soma 5 com:
- 1 subwoofer (que é o 0,1 em 5,1)
Um 5.1.2 incluiria todos os itens acima, mas também talvez tivesse 2 alto-falantes de altura Atmos. Esse é o .2 no final de 5.1.2
É possível ter 5.1.2 ou 5.2.2 ou 7.2.2 ou 7.2.4 etc. Depois de obter isso, ajuda a entender como tudo funciona.
Se você for a um cinema Dolby Atmos, pode haver até 36 alto-falantes no espaço para criar o efeito máximo, isso obviamente não é possível em casa.
Existem dois tipos básicos de alto-falantes Dolby Atmos para conjunto de home theater acima.
1:alto-falantes Dolby Atmos montados no teto
O primeiro é um alto-falante de disparo descendente montado no teto que é colocado no teto em uma das duas posições principais. Geralmente, os alto-falantes montados no teto são colocados ligeiramente à frente da posição de audição e disparam diretamente para baixo, acima de você.
Dependendo de quantos canais você tem, também indicará quantas opções de teto você tem. Não há dúvida de que esta é a configuração ideal para alto-falantes de altura Dolby Atmos
2:Reflective up-firing Dolby Atmos speakers, or add on Atmos speakers.
Most of us can’t just cut holes in the ceiling or get out partners approval to screw speakers into the ceiling. Fortunately, there is a middle ground that, while sacrificing some audio quality, is an acceptable workaround.
These are up-firing Atmos speakers which work by shooting height sounds (rain, aircraft overpasses, birds in trees etc) from the front speakers up against the roof which then reflects down to the listener’s ear.
It ideally works with a 12-14” ceiling height and to date one of the best ways to put Dolby atmos speakers into a vaulted ceiling is to suspend a front-firing unit suspended from the ceiling with cables and angle it to shoot straight down. The benefit of this is that is is a closed box unit.
Are Dolby Speakers different? Can I just use bookshelf/surround speakers for Atmos height channels?
We tried using bookshelf speakers to test the Atmos channel and see if this Atmos stuff even works. We thought ‘surely you could use any small speaker to project the Atmos height channel, right?’.
In theory, yes, you could use a different speaker to shoot the sound of the ceiling and down to the listener but after some research (re:audioholics) it turns out that Dolby licensed speakers (yes, you have to be licensed to build Atmos specific speakers) have a very complex crossover configuration.
As a purist, this leads me to believe that there is some benefit to buying a legitimate license Atmos speaker for my home theatre. There are two reasons for this:
1: It’s more foolproof – less need to fuss with setting frequency crossovers etc. Plug and play.
2: These things are designed to sit nicely on your existing floor standing speakers or be mounted to the wall. Putting our bookshelf speakers on our floor standing speakers was a ridiculous idea. It looks stupid, was probably dangerous for small beings and we’d prefer to use our bookshelf’s elsewhere.
How to Dolby Atmos speakers work?
Dolby Atmos soundtracks are different from regular old 5.1 mixed soundtracks. Atmos is about the position of the sound object in the room and the Atmos-enabled amp just places the sound there with the speakers adjusting almost as if they were acting as one. 5.1 required sound engineers to select which sounds travelled down to which speaker.
You would think Atmos would be easier for audio engineers to mix but this is not the case – it’s actually quite expensive and time-intensive.
Dolby Atmos height speakers take these high ‘objects’ (think bird noise, train track clanking, plane up high) from the soundtrack and play them from an elevated position.
If you have ceiling speakers the sounds come down from the roof – like rain falling, a plane flying overhead, ambient noise, a bird flying overhead etc.
If you have
up-firing atmos speakers they drive the sound at the roof and it bounces off and comes down to the seated position. As this is mostly ambient noises only it doesn’t need to be as clear and distinct as a direct sound like voice track.
Do Dolby Atmos speakers work? Are they any good?
Yes – ceiling mounted work best but in our experience, up-firing units work too. If you have a sound room set up a system like audessy (Denon et al) or YPAO (Yamaha) on your home theatre unit you can trust it to configure these correctly. You might want to play with the angle of the speaker depending on how far your listening position is.
Which Dolby Atmos speakers should you choose?
Atmos height speakers are fundamentally quite similar. They focus on a key frequency range, have Dolby approved crossovers and circuitry and are designed to fill the room with noise. Using the recommended Denon Atmos testing tracks are good fun to play with when you have it all set up. This includes the
Dolby leaf trailer and the
Dolby amaze trailer . This will heighten the impact of any Dolby atmos set.
If you want to impress your friends and family once your home theatre is booming then definitely go for the amaze testing track and turn it up loud.

Where to buy Dolby Atmos speakers?
Your local HiFi store should stock a version of Atmos speakers but due to their limited audience (mostly as people don’t have Atmos-enabled HiFi amplifiers), you might find slim pickings. Amazon has the widest range available to review. Both on Atmos speakers Amazon US and Atmos speakers Amazon UK. We’ll detail these more below.
Best Dolby Atmos speakers for home?
Here is a list of Atmos Dolby speakers available for home – designed to be added to your existing setups to support a height channel.
I’ve included links for pricing in
US and
UK where possible to make it easier to check prices and availability. The UK has less selection available so UK prices are marked where there is a price to show.
Any prices I post now will change too often. I’ve also ranked these in order of best based on my extensive research. Best meaning sound quality, reviews and price.
Something worth noting is the coverage area for up-firing speakers differs so if you have a large space to cover it’s worth noting what might not work for you.
15 Best Dolby Atmos Speakers List
1:ELAC Debut 2.0 A4.2 Dolby Atmos Modules
Our pick of the bunch . There is no doubt the Klipsch has some tasty models but price + looks + sound makes these a good overall great pick. A nice slimline profile that isn’t too flashy. The angle might require a small tweak depending on where you are sitting in the room i.e how far from the TV. A little shiv (just kidding, a fat coin or anything small might be enough) at the back will lift the angle slightly.
The ELAC also have a good coverage area. This is the overall area the speaker sound covers when bouncing off the roof. Our lounge is a little bigger and longer than most so the more sound coverage the better.
2:Sony SSCSE Dolby Atmos Enabled Speakers
Serious Contender :Coming through strong for a mainstream manufacturer. The Sony SSCSE win a lot of fans, being well priced and not unattractive at all. They are part of a complementary system from Sony but make a perfect stand-alone.
They are a similar size to the ELAC but have a slightly higher profile and slightly smaller coverage area. Personally, I’d like a lower profile but the angle of these is good.
3:Pioneer SP-T22A-LR Add-on Speaker Modules
Designed for use with the SP-FS52 and SP-BS22-LR but can be used anywhere. Might look odd on ill-fitting speakers and the rounded edges are a personal taste choice. These have quite a flat top so angle to taste, depending on the size of your room.
4:NHT Atmos Mini Add-On Speaker for Dolby Atmos
Be careful as this NHT Atmos Mini is a single unit item so you need to buy 2 unless otherwise stated. These have really great reviews so if NHT can just start selling 2 at a time, for a little less money, they’ll sell a hell of a lot more units I expect. They are surprisingly small but pack a punch.
The coverage area isn’t huge but as big as the Sony and many others on this list which is impressive. NHT have quite a bit of street cred and these are a popular unit.
These would be perfect for the top of my Concept 40 Q Acoustic speakers so it’s likely if the ELAC don’t sing, these will be next in line.
They also have wall mounting options which is great. Can be suspended up the wall above your floor standing speakers rather than on, and because of their smaller profile it is not an unattractive look.
5:Klipsch RP-140SA Dolby Atmos Speaker (Pair)
We’ve got these in our Home Theatre set up now so you can read the full review here
It’s Klipsch, it’s skinny but as you’ll see from this list, Klipsch has done a lot more in the Dolby atmos up-firing speaker line than most.
They sit at the top end overall for the category but as many audiophiles have a love of Klipsch for home theatre, these are an affordable luxury.
These are in that mid-range of not too expensive and not too cheap but still packing a solid punch.
6:Onkyo SKH-410 Dolby Atmos-enabled Speaker
One of the first and most widely purchased units. These could be considered the cheap and cheerful but when you consider these are ambient speakers and not driving hardcore audiophile bliss, they are a great value!
A smaller box with a high stance, they will make a good choice for most floor standing partnerships. Personally, I’m looking for something that doesn’t stand so tall on top of my already tall floor standing speakers but on a budget, these are an absolutely winning choice.
7:POLK Reserve R900 Height Speaker Modules
New for 2021 Polk are entering the Dolby Atmos space with a full 9 speaker line up that is the Polk Reserve range. Some very cool options in this line up and your spoiled for choice.
This is a premium range and the R900 height modules are designed to either be used on the wall or on the top of a tower speaker (or similar). These are Dolby Atmos licensed / DTS:X and have a cool switch on the back of the height speakers that allows you to choose whether you are using them on a wall (down firing) or on a tower speaker top.
These sit in the expensive range for sure. Polk obviously decided if they were going to do it, they were going to do it right.
8:SVS Prime Elevation Speaker
SVS doesn’t take prisoners so if you like a full sounding smack in your face experience, even with your Dolby height speakers, then these might be your happy place. In fact, the whole Prime range of speakers from SVS are sublime.
These are without a doubt the most versatile Atmos, DTS:X®, Auro-3D® speaker in the range. They can be used as up-firing or down-firing speakers depending on where you place them in the room.
It’s important to note that these are
not technically licensed Atmos Dolby speakers but they are still a great height speaker choice for Atmos and worth being in the list, in my opinion.
Two examples below:
If you buy a pair and wire them correctly then the SVS Prime Elevation can also be bipole or dipole speakers.
Getting more expensive here but a serious contender with Klipsch at the price point they sit at. The A90 have a different form factor and have a faithful following and a good choice for speakers for Atmos.
10:Klipsch RP-500SA Dolby Atmos Surround Sound Speakers
You only have to see the copper coil finish on the speaker cones to know they are Klipsch and know they are going to cost you a considerable amount of money. It’s hard to deny such attractive, impactful sound so if you have the budget – have at ’em.
11:Atlantic Technology Dolby Atmos Speakers
The price on these is for a pair of the 44-DA-P-BLK. This is a square unit, odd right? Atlantic has bucked the trend and gone with a square casing which houses a 5.25″ woofer and 1″ silk dome tweeter. Lots of fans for silk dome tweeters out there.
These things are not cheap but they certainly stand out as a great option for people who want to add the Atmos height speakers without having a triangle shape on their existing speakers. These units match better with most floor-standing speakers which are all rectangle or square. See image below:
12:PRESTIGE FACET 6ATM Dolby Atmos-enabled Speakers
Elipson is a French company who have a full Dolby Atmos 7.2.4 speaker set up in this Prestige Facet collection. The Facet 6ATM is the Dolby Height speaker in the collection and can be purchased separately.
The 6ATM can handle up to 70W and have a frequency response of 65Hz-25kHz.
The build quality and sound quality of the Elipson is really impressive and the package for the price is excellent. While not new the Elipson Prestige was originally released in 1970 and updated in 2016 it is still a strong choice especially if you are in the EU or UK.
You can purchase them direct from Elipson and they come in three finishes. Black lacquered, White and Walnut finish.
13:ONKYO Dolby Atmos-enabled speakers (2 units) D-309H
Another older unit with mixed feedback. The Onkyo SKH-410 seems to outsell this unit or has done over the past couple of years at least since launch. 6 Ohm with 80 watts of power, the price isn’t cheap enough currently to warrant a fresh look. Worth noting the price is for a pair.
The piano black high gloss finish is attractive and it has a 10cm driver and 1.2cm balance tweeter. I think these are a great looking unit weighing about 2.2kg. Would match my Concept 40 Q Acoustics nicely with the gloss.
14:KEF Q50a Dolby Atmos Speaker
This is the newest model from KEF that is definitely worth a look. The best part? They come in BLACK and WHITE. There are very few White Dolby Atmos speakers so these will definitely strike a chord with many audiophiles. Price is a little higher than some others but we love how these look. The price includes a pair.
Similar in core design to the KEF R50 but without all the shiny bits. While the Q50a is sonically matched to KEF speakers but as these are an ambient speaker they will pair with anything well enough. If the design of these isn’t enough to woo you, the sound will.
15:Klipsch R-41SA Dolby Atmos Speakers
A replacement for the R-14SA model this newer unit (released 2017) is current the choice for Klipsch Atmos upfiring sales. It’s currently top pick for Klipsch Atmos so that is usually a sign sales are going well.
The R-41SA has a 4″ driver, in spun copper as Klipsch is so known for. It also has a 1″ tweeter which is made from Aluminum and connected into a 90 x 90 horn. Handles a generous 100W of power and is fully Dolby certified, of course.
See more about the Klipsch R-41SA Dolby Atmos Speakers
16:Monitor Audio Bronze AMS Dolby Atmos® enabled Speaker
New in 2020, the Monitor Audio Bronze AMS Atmos® enabled speaker comes in an attractive White and Black colour option. With a 60 watts rms power rating and a crossover at 2,500 Hz this is subtle enough and sharp enough to give you the Dolby height or upfiring audio you need.
While the Monitor Audio Bronze AMS atmos speaker is designed to pair nicely with the monitor audio bronze and silver range, it can also make a great partner with other floorstanding or bookshelf combinations.
I personally enjoyed the audio signal of the Silver 200 series (not as much as my Concept 40’s) and so you can expect these will provide similar speed and efficiency typical of Monitor Audio gear.
See more about the Monitor Audio Bronze Atmos height speaker
17:DALI ALTECO C-1 Height Speakers
Similar to the SVS Prime Elevation speakers the DALI ALTECO C-1 are not technically licensed but they have built a great height speaker with flexible options that are perfect for Atmos use. They are a little of a cross between an SVS Prime Elevation and a Klipsch RP-500 as it can be used as an up-firing speaker sitting on your existing front floorstanding units or on your back surrounds facing up.
The little switch on the front lets you switch between usage modes. If you want to use the speakers up high, positioned facing down just a switch change and you can mount them on the wall as front/back down-firing or back surrounds.
Your ATMOS enable amp will do all the pre-work and send these the signal they need. Also great for DTS-X and Auro-3D audio.
See more about the DALI ALTECO C-1
18:MartinLogan AFX Dolby Atmos Speakers
If you’re a MartinLogan fan then the AFX is where you might start when you’re looking for Atmos speakers. At first look, they seem huge like a subwoofer size, but they are still designed to sit on the top of your floor standing speakers at the front and/or back.
While designed for use with the Motion series (20, 40 etc) from MartinLogan you can use them as you like on other systems. They include a 4″ woofer and .75″ high end. I think these would also look OK on my Q Acoustic Concept 40’s as they have gloss black finish.
This AFX atmos height speaker is sold in pairs.
See more about the MartinLogan AFX Dolby Atmos Speaker
Dolby Atmos Floorstanding Speaker List

- NHT Media Series Dolby Atmos Tower Speaker
- Pioneer Elite SP-EFS73 Andrew Jones Floor Standing Atmos Speaker
- Klipsch RP-8060 FA Dolby Atmos Floorstanding Speaker
- Focal Chora 826-D Dolby Atmos Floorstanding Speaker

- OSD 6.5 Angled Ceiling Dolby Atmos Speaker
- Micca M-8C 8 Inch 2-Way in-Ceiling in-Wall Speaker
- Klipsch R-1650-C In-Ceiling Speaker

Perguntas frequentes
Are Dolby Atmos speakers different?
Sim. There is a specially licensed cross-over in a Dolby Atmos speaker. In conjunction with the amp this manages what frequencies get sent to the Dolby Atmos speakers, especially the height speakers.
How to add Dolby Atmos speakers?
You need to ensure you have a HiFi/Home Theatre amp capable of handling Dolby Atmos. You also need to make sure your source files are Dolby Atmos. Most Apple Movies and Google Play streaming movies are in Dolby. You can get Atmos streaming on Netflix with a premium subscription. Your amp will have height output speaker connections on the back of the amplifier which you will connect your height speakers too.
If you have floor standing Dolby Atmos speakers you will have additional connectors on the wiring plate on the back of the speaker for Atmos speakers.
Dolby Atmos speakers vs normal
The difference between Dolby Atmos and normal speakers is the internal crossover design. This allows the source, amp and speaker to play the specific sounds to that space in the soundscape. Unlike normal audio which is sent in channels directly to a specific speaker, Dolby Atmos audio is sound that is placed in the room by using all speakers as a soundstage. This helps you feel like the audio is everywhere and sounds like helicopters, rockets overhead or 3D sounds are all around you.
Conclusion
Quite a few choices but when you look at them a few stand out based on either form factor and size, or power output and area coverage.
We’ve chosen the ELAC 2.0 as our best of the bunch but as the Dolby Atmos speakers are mostly there to highlight ambient height sounds, it might really come down to what looks best on your floor standing speakers, or what is going to look best on your wall.

Former Dobly Atmos speakers retired from this list
The
KEF R50 seem to have passed quietly in to the night and been replaced with the better reviewed KEF Q50a Dolby Atmos speaker. It has been retired from the list now.
