I did use the email form.

I just sent them a message through Facebook Messenger and they responded immediately. They're going to hold the soundbar for me until I move into my new place, which is very nice of them.

A few more thoughts about the whole subject of immersive audio, various technologies used to reproduce it, and the need to keep an ope, experimentative mind.

It's been my inderstanding that there is height information even in material not encoded in Atmos, DTS X, or Auro 3D. When microphones pick up sound, there is a lt of information that gets recorded, including complex reflections, and variations in amplitide and frequency. Again, from my understanding a lot of this information is preserved even in stereo, 5,1, etc. So I found this interesting in an article about Dolby Pro Logic IIz:

"...Most surround sound solutions use digital signal processing (DSP) to artificially model listening environments. Expanding on proven Dolby Pro Logic IIx technology, Dolby Pro Logic IIz identifies and decodes spatial cues that occur naturally in all content—stereo and 5.1 broadcast, music CDs, DVDs, 5.1- and 7.1-channel Blu-ray Discs™, and video games. It then processes ambient sound and certain amorphous effects such as rain or wind and directs them to the front height speakers...."


ya agree with that. Typically the height information is simulated via front speakers. Of course with the benefit of discrete height speakers, the height element will be more prominent and precise.

I'm still waiting for a response from Nakamichi regarding my question about Atmos source material. With regards to the soundbar, it should reproduce DTS X height effects utilizing DTS Virtual X. Unlike the Yamaha YAS 207, the Soundbar does have a decoder to interpret the height information, and then reproduce it using Virtual X. This will be interesting to hear, as in this case you will have a good number of physical speakers around the room as a basis for the Virtual X effect.

I did find out that all of the drivers on the Ultra 9.2 Soundbar are new and upgraded over the 7.1 Pro, which is good news.

Regarding Atmos, it's not just that it requires either ceiling or ceiling reflecting speakers, but it also appears to require fairly specific placement horizontally. DTS X can work with many different combinations of speakers.

The reason I speculated about whether the output of Blu-ray players had an effect on how these various soundbars handle source material, is based on the long discussion on the Samsung 950 thread, as that sound bar decodes Atmos but not DTS. It emerged that a number of players could convert the Atmos encoded discs into a form that the 950 could handle. It may be that this is converted to 5.1, but as the Samsung does have an Atmos decoder, and does also virtualize height from 5.1 sources, I was wondering about something similar with the Nakamichi.

I think with a number of these devices you have to simply try them, and not argue a priori what effects a particular device can and cannot do. I go back to my old TV with its simple surround simulation mode. I'm sure there is no decoder present, but with some audio sources I can hear effects far to the right and left of the TV, and sometimes quite a bit to the sides. Sometimes the effect is so dramatic that I look to see if something is actually there.

Even with the lowly YAS 207, I'm willing to bet some discs sound more convincing than others. One of the reviews I read tested the movie Spectre and also Inferno, and these apparently produced pretty pleasing atmospheric effects that were consistent with the film.
Based on my recent research, I have couple of observations:

DTSX doesn't require height speakers while dolby Atmos has strict requirement on the speaker placement, including at least a pair of height speaker in order to work properly. DTSX can have some form of virtualisation via front speakers, even without virtual X technology in place.

if the bluray players can output both dolby Atmos and dtsX altogether, the soundbar will be benefit from it by decoding the stream. Otherwise, the soundbar will utilise either built-in dolby surround or dts neural X (comes with dtsX) to upmix the stream to Atmos/dtsX. However, it is not possible to remix/upmix dolby Atmos content to DTSX content via neural X upmixer and vice versa. I noticed there is someone mentioning about Nakamichi comes with Neural X so I guess this is pretty much the case.

I am still looking around to find out whats the best deal for my home entertainment system. Maybe I should give the Ultra 9.2 a go since the reviews on previous nakamichi sound bar were pretty good.

sounds tempting but the majority of UHD discs are coming with Atmos soundtracks and not DTS:X

so once I find out how the Ultra 9.2 will handle when Atmos is thrown at it, that'll help me decide between this and the Sony HT-ST5000

I think you put it pretty well, and make excellent points. Although it's all hypothetical until we hear it, the Nakamichi offers something that the Sony doesn't offer yet...rear speakers. And Atmos 7.1.2 isn't full 7.1.4. Moreover the potential for rear and sides, and the sonic presence of two subs is persuasive, Lastly, from my emails with Nakamichi, it looks like they're putting a lot of engineering into their drivers,

Ya dual wireless subs and rear speakers are the key factors that get me interested into the new nakamichi solution. it is rare to see such configuration nowadays in the market. I don't mind to spare a bit more space for the setup if the system can get the sound right in my space. I am not exactly sure about the whole virtualisation thingy can do the job in my space with the high ceiling design. Discrete surround speakers do give me better assurance for better surround audio effects.

Hope to see more reviews on the nakamichi before the pre-order end. It looks really promising in audio perspective.

The virualization is completely independent of your ceilings, It's using phase, delay, and amplitude variations to tell your brain and ears where the sound is coming from. No reflections involved.

I think this will be fine for me. After a certain point all the gimmicks don't matter.

The only thing that concerns me is that since I don't have a wall on one side of my room I'll have to keep the speakers together. The person I interacted with from
Nakamichi said that in that configuration it will still provide better imaging than the 7.2 setup.

Oh yes you are right. I didn't mention it clearly I was actually referring to those who involved ceiling-bound Atmos soundbar, like the Sony HT-ST5000. But it is great to know that the virtualisation is independent of my ceiling.

Well I guess for your case, having discrete surround speakers will produce better and more consistent result than a single soundbar with audio bouncing off here and there.

That review must be wrong. The difference between the 7.2 and 9.2 is the addition of side speaker for the 9.2 (or a dipole double, rear speaker if you choose). The satellites are not wireless from all I've read. I would keep the 9.2 for superior sound.

Well technically the reviewer is not wrong about. You don’t have to run the wires across the room. The satellites are attached to the subwoofer while the subwoofers are wirelessly connected to the sound bar. It is not perfect but the good news is you don’t have to allocate individual power supply for each satellite. The signal and power will be tapped from the subs. Pretty neat.

I think he just means you don't have to run wires from the front of the room to the surrounds. Yes you have to run wires from the subs to the satellites, but you can strategically place them (ie: both sides of the couch, with the wires under the couch, etc).

I'm just wondering how the 9.2 in the dipole double configuration will be wired? Is it two wires to each, or one? Can you still mount them on speaker stands in their double configuration?

Are the 7.2 and 9.2 setups the same with only an additional 2 speakers? Can I buy the 7.2 setup and add 2 more speakers if I decide to later on?

I'm going to have to talk to Nakamichi more before I make my decision. I really won't know my ideal setup until I'm in my new apartment and all my furniture is in place.

Regarding the Amazon reviewer ( I only read the quote posted here) saying there are no wires running across the living room, across can refer to either the room's long or short (or equal) dimension of the living room. Of course there are wires running across some part of the room. The likelihood is that each satellite has two wires, and each sub four inputs. Putting the side and rear together has acoustical ramifications, but the wiring would remain the same, unless Nakamichi has some consolidated master cable running from the dipole configuration, which is possible but not likely. Nevertheless, the best thing is to ask Nakamichi. But the 9.2 will provide a much fuller sound than the 7.2.

That reviewer says there are no wires running across the living room- that is my biggest concern. I'm wondering if I should cancel my order for the 9.2 and go with the 7.2?

If I keep the 9.2 speakers together hopefully that should solve the problem.
To my understanding, there are two normal RCA type wires that run from each subwoofer to the rear speakers (Dipole or 9.2).

I think the difference is more power, two more rear speakers and 10" Vs 8" Subwoofers from what I have read, not sure if there are other technical differences.
