Trying to wrap my brain around Atmos. For a 7.1.4 setup (for instance) does it matter if the surround speakers in the 7 speaker configuration contain some bipole surrounds? Or should all surround speakers be monopole and match the additional 4 Atmos speakers? Can I keep my current setup and just add the additional Atmos surrounds (in my situation in-ceiling)?

At the a Dolby training class at Cedia, they weren't saying NOT to use bipolar/dipolar speakers but the recommended spec is monopolar.

Monopolar for just the Atmos overhead speakers or would I also have to replace the rear and side surround speakers in the original 7.1 setup with monopolar?

All of them. Wide dispersion monopoles work best.

Listen up, studios! Just say "NO" to DNR and EE!!

Had THX certification come out and endorse monopole over their prior Di-pole recommendation?
I've not seen anything on that.

THX is irrelevant to this discussion. They did not come up with these immersive sound formats. Dolby, Auro, and DTS do recommend switching to timbre matched monopole surrounds (wide dispersion characteristics are even better) for 3D audio since you can actually now have a surround array just like at the cinemas, especially with Dolby and DTS's object based formats. Dipoles, especially, smear the 3D effect the mixers are trying to create.

Dolby state that if the speakers image well then they are fine to use. Tripole speakers work as well in n Atmos system as they do in present 5.1/7.1 systems.

This is also using tripoles for ceiling speakers. Do not dismiss it until you have heard it. This is from direct comparisons in non dedicated and dedicated cinema rooms running a full MK300 suite and and a full MK150 mk2 system in separate rooms.

Dan,
You and I know that, I was asking has THX changed their stance, being a post-object sound world now they have to play in the same sandbox as others.

THX has pretty much dropped off the radar as far as the electronics companies are concerned. They don't want to pay for certification that amounts to (in this day and age in consumer land): THX... what the hell is that?

To those who have arrays of surround speakers (example 2x LeftSurround, 2x RightSurround) for multi-row seating, how do you time-align these surround speakers?

Is it possible to mix surround sound speakers and bookshelves? Considering a 7.1 Setup, something simple as i live in an apartment complex. Purchased a v577 yamaha receiver and klipsch 12hg sub on sale. Considering getting some Floorstanding for the front and am trying to decide whether to get four bookshelf speakers for the side and rear or a combination of two bookshelf for the back and two surround sound speakers for the side.

Should you combine the two or simple stick to the bookshelves?

Thanks!

If you're going to upgrade to Dolby Atmos in the future... four matching bookshelves (that are from the same "family" as your front three) would probably work better. At the very least scratch dipole surrounds off your list. They're fast becoming passe with these new 3D audio formats.

Hi guys continuing with the Atmos talk

I was thinking of buying Axiom QS8 for rear surrounds so would a 2 front atmos setup work good or is better to drop the QS8 and get 2 monopoles for a 4 speaker atmos setup

5.2.2 just two atmos front plus the QS8
or
5.2.4 four atmos plus back monopoles

I like that the QS8 could be setup on the wall as is a small room just under 11'x11'
as there are not many front ported monopoles.

also another question do the atmos AVR scale all the movies for atmos or the DVDs have to be recorded that way for it to work.

Thanks!

For Atmos, 4 would definitely be more noticeable than the 2'rear surrounds. I own q8's (both sides and rear), but the rears don't seem to do much. I do like the Q8's though: it seems to me that real sounds are omnidirectional and the Q8's simulate this better than monopoles or dipoles. They also seem to expand the size of the room. BUT I've heard the Dolby guys recommend direct radiators as surrounds, and I don't claim to know more than they do.

Bipole and Tripole work perfectly well in an Atmos system.

I just checked my speakercraft cinema dipole threes (4 x speakers as both my side and rear surrounds). They have all been on the QFX setting since my 7.2.4 Atmos system has been up and running (did not check before since I am happy with what I am hearing). QFX means HF signal radiates in Dipole Mode while M/L frequencies radiate in Bipole Mode. The other two options for these speakers are Dipole only and Bipole only.

As I stated before, I have been really happy with my set up as I have been able to localize sounds in 3D space (not attributed to a specific speaker). Over the next few nights I will test the other modes on these speakers in order to optimize the Atmos effect. I may find out that the way I was listening is optimum. However, although conflicting guidance exists, the preponderance of the recommendations have been for monopole in favor over Bipole, and Bipole in favor over Dipole.

If QFX settings have been giving me HF signals in Dipole, I would assume this was not giving me optimal results. But again, I have been blown away by how awesome both DSU and ATMOS have enveloped me in a sea of sounds.

Has anyone else tested these different settings on their speakers? If so, what sounded best to you?

I'll report my results here this weekend. I'll post on the official Atmos thread too.

I think the monopole recommendation has the Atmos circle/canopy in mind, with multiple screen, side, rear and ceiling speakers. This is what will sound best with the full array. If you are mainly listening to 5.1 or 7.1 soundtracks with that amount of speakers, then keeping any dipoles in your system for the time being wouldn't be bad. As has been mentioned, when we all go full object eventually, the multiple wide dispersion monopoles will be the recommendation.
