Now to the positive. Bass, "OMG" that's the only way to describe it. For an apartment its way too much, but there are so many adjustments and you can make to the bass and treble that can balance it out. But to say the bass isn't that great like some reviews say is just silly. Its almost like some people need something to complain about to make it sound like a "critical review," but pay no attention to those reviews, the bass is spectacular. Setup takes about an hour or so, but once its set up control is easy. I have an Apple TV 4k, PS4 Pro, and Sony X700 bluray player attached to it, and I have the sound bar plugged in using eArc to an LG Nano9 65 inch TV. I have 2 satellite speakers up by the TV and 2 near my couch which adds great surround sound effect. So far on apple tv i have watch John Wick, Interstellar (that scene with the ocean world is really intense), and Batman Begins. John Wick is done in Dolby Atmos, which sounds amazing and I have been hearing sounds I have never heard in surround sound. But even Interstellar and Batman Begins being in Dolby 5.1 sound great. The sound bar has amazing clarity, especially if your willing to take the time to adjust it to settings you will like. I listen to apple music a lot, heavy bass for hip hop, then take down to more of a clarity setting for 80s rock and it handles both really well. When I watch scrubs (my favorite show), it offers a ton clarity as well.
In my personal opinion there is only two drawback and one is minor, the other is a good problem to have. The first is the satellite speakers can be a little lite on sound, which is okay because you will still know they are there, especially in atmos movies, but that is just not enough to take a star away. The second is of course the bass, its not that it is bad, its too good for an apartment so I have yet to fully experiment with it which sucks. So if your gonna get it for an apartment like me that may be a little bit of a let down unless you don't care about your neighbors lol.
Overall this is a great system, the best on the market for "sound bars" if you can call it that. To be honest its really more of a home theater in a box than anything else. It pairs so nicely with the Apple TV 4k which offer by far the largest streaming library of Dolby Atmos/Vision Movies. The only reason I get a 4K bluray player is that I ordered the 4K special edition marvel movies that all now have atmos (which comes in next week!). But honestly everything else can be watch on Apple TV, which if your like me and you love movies than the combination is of the Nakamichi 9.2.4 and the Apple TV 4k should set you up for years to come. Don't hesitate to get this system, its well worth it I promise.
Bedroom
LG OLED65C6P
Samsung UBD K8500
When looking for a sound bar, I had a few requirements.
1. It had to have 4K and HDR options
2. It had to have something better than basic Dolby/DTS processing
3. It had to fit the space requirements
Initially, I was going to just get a sound bar without surround, but I grew to like the sound from my LG OLED. It wasn't bad. However, my C6P has fantastic 3D, while my home theater tv has crosstalk issues that make it unwatchable to me. This left me having to choose between watching a movie in 3D or watching it with 7.1 surround. So I decided to look for a sound bar with 5.1 to 7.1. Unfortunately, there's not a lot of options in that group that have 4K, HDR, Atmos or DTSX.. Well, there are if you want simulated surround.
Originally, I had listed the Nakamichi Shockwafe 7.1 as one of two sound bars I was interested in. So when I started looking again, the Ultra 9.2 was listed... Certainly there was a catch! No, there's no catch. 1000W system, 4K HDR passthrough, Dolby processing and DTS:X. Checked the measurements to be sure I could fit this all in the bedroom... Requirements met!
While in transit, I noticed the lack of Atmos/TrueHD and the lack of Dolby Vision. An oversight on my part. Perhaps I'm used to home theater receivers... When I recently bought an Onkyo RZ920, the flagship model, there was no question about HDR, Dolby Vision, Atmos or DTS:X. A flagship audio component should be be just that... The model that does it all, no questions asked. So, when purchasing the Nakamichi Shockwafe Ultra 9.2, I assumed no questions asked. After all, this is Nakamichi, a brand that years back was considered one of the great audiophile brands. Still, having read posts on AVSForum, it appears these things (7.1 TrueHD decoding and Dolby Vision passthrough) can be added via firmware updates, should Nakamichi decide to do so. Not likely though seems to be the general feeling as sound bars take sides in the Dolby vs DTS war.
One other thing of note is that this system is intended to have the subwoofers at the rear since the rear speakers also plug into them with RCA plugs. You can place them at the front and run the included cables, but they're about 16ft long. The cables are also about the same thickness of the cable to your phone's wired earbuds. I replaced mine with heavier 25ft RCA cables.
No regrets though. Despite the lack of native 7.1 TrueHD or Dolby Vision, I would still be searching for something if I wanted everything. That's just the way sound bars are.
Setup was simple enough. Unpack, plug in the HDMI cables and power cords. Connect the rear speakers to the subwoofers (be sure to connect left rears to the left subwoofer and right rears to the right subwoofer) and turn it all on. The subwoofers automatically pair (via bluetooth) to the sound bar.
First impressions were not what I expected. I played Guardians of the Galaxy 2 via the LG Netflix app. It seemed muddled. Turns out there were a few things going on, but after tweaking the settings and sitting a little further back, everything was good!
My primary movie settings are...
DSP: Off (Movie setting adds more bass, but the clarity of the sound gets taken out back)
Pure: Off (enables DTS Neural:X processing/upmixing)
Bass: 7 (after a lot of testing with Passengers, 6 or 7 seems to be about the highest setting before voices were affected)
Treble: 7 (just to match the Bass setting)
Center: 10 (helps with the voice clarity)
SR: 7 (I noticed almost no change between 1 to 10 while watching movies, but while listening to music, it was night and day)
SB: 7 (I noticed almost no change between 1 to 10 while watching movies, but while listening to music, it was night and day)
Now, you might be wondering, what do I compare this to.
Well, that's not easy or fair to answer... My home theater system is an LG 86UH9500 tv, Onkyo RZ920 receiver, Oppo UDP 203 4k player, with Klipsch Forte speakers (front), Klipsch KSC-C1 (center), Klipsch WB14 speakers (surround), Acoustic Research M1 speakers (rear), and a Velodyne subwoofer. This is like comparing a soccer mom's mini van to a Porsche 911, and thus not a fair comparison. What would be fair though is perhaps to compare to the Logitech Z906 system I have connected to the computer.
The Logitech Z906 is a true 5.1 surround system that at full price will cost you $400. Now, the Z906 has flaws. It hasn't been updated in years, and it doesn't have HDMI inputs, so it's not a good option for a home theater setup unless you don't mind using optical/coax and being limited to basic Dolby and DTS processing. Despite all that, used it for years to watch movies on the computer in the bedroom. That being said, if Logitech had ever updated it with HDMI and 4K HDR passthrough, I would have bought that without a second thought since I'm familiar with it.
Coming back to the Ultra 9.2, the sound quality is good. I'm not going to spend hours comparing apples and oranges, but with years of the Z906, I'd say the sound quality of the speakers here are just as good, but technologically, there's more of them, and they do a lot more with DTS:X and Neural:X supporting it. I've spent a bit of time with it watching the first 2 Hunger Games movies in 4K (as well as testing a bunch of movies while setting up the audio) and I've been pleased with the results.
The only real weakness I find is the subwoofers. There's 2 of them, and I expected a lot more room shaking punch. They're really about the same as the subwoofer that comes with the Z906, except they're downward firing while the Logitech is front firing. The impact is right about the same when I gave it the Jurassic Park test. T-Rex won't scare anyone or anything with either. Safe to say, the home theater Velodyne makes things fall down, but again, that's not a fair comparison. Also the placement could be a factor. Firmware updates since the original release also make them a bit heavier sounding.
I have experienced some odd issues since setting up the Nakamichi. The UHD player sometimes appears to have a stroke and believes it no longer has an HDCP 2.2 connection and reverts to 1080p. Twice now has my TV had a stroke and just starts turning 3D on and off for no reason. And a few times now my Roku 4 picture looks like it was put through a blender and reprocessed in 8bit pixelated gaming Minecraft blocks, and the issue appears to be with HDCP 2.2 going AWOL. The last issue is related to startup. I use a Logitech Harmony remote, and when turning everything on, the Nakamichi input will change as intended, but then it will for no reason decide it wants to be on ARC (HDMI 1) and switch back. This is an issue after starting up, and it doesn't always happen. It seems I need to wait at least 15 seconds before changing the input, otherwise it will always go right back to ARC or won't change at all. I'm hoping this gets worked out with firmware.
Lastly, I mentioned a lack of Dolby Vision and 7.1 TrueHD. Dolby Vision isn't on a lot of components. If you happen to have an LG TV and an Oppo player, you can simply use the HDMI audio out of the player to plug into the player, and leave the HDMI video to the TV. In the case of 7.1 TrueHD, you can set your UHD player to PCM instead of bitstream to maintain lossless audio, as suggested on AVSForum. However, you'll want to change it back for DTS:X audio. Personally, I say just leave it on bitstream, and disable Pure mode so that Neural:X can just do its thing. Yes, it's lossy audio then, but I'd be amazed if anyone could tell the difference on a sound bar system. Just the same way 192 bitrate MP3s work fine on your phone with earbuds, but you'll notice it if you play that same MP3 on a high end audio system.
So let's end this. The Nakamichi Ultra 9.2 is a one of a kind. It's a real 7.2/9.2 surround system with DTS:X, and 4K HDR passthrough. In the sound bar market, there's nothing else like it. It achieves what it set out to do, and Nakamichi should be proud of it. Yes, there's room for improvement, and I'm sure Nakamichi knows this, but only time will tell what comes next.
I would probably give this 4 out of 5 because of the lack of lossless TrueHD and Dolby Vision since this is the flagship, and it is Nakamichi. However, I'm going to let it slide because you can work arounds stated above. There's the issues I've run into as well, but I'm confident firmware updates will resolve it. A few interactions with support have left me feeling Nakamichi really wants to be liked the same way they were long ago. It's under warranty, so I have time if firmware fixes are not an option. For what this is, a 7.2/9.2 sound bar surround system, there's currently no equal.
UPDATE: November 12, 2018
Nakamichi has announced an update that will now include Dolby Atmos and Dolby Vision. This update will be available for those of us who already own the system via firmware. This is a big deal! Nakamichi already had a superior soundbar system here, but now it's going to even better.
I've lived with this system for nearly a year now, and the Shockwafe 9.2 has remained everything I hoped for as a bedroom system. I stand firm in that if you can afford a real surround system that includes an A/V receiver, and stand alone speakers, and the technical knowledge to set it up, that THAT is a far superior experience. However, for ease of use, space saving, and lower cost, THIS will obliterate whatever speakers your TV has, and give you a home theater experience from a soundbar system that no other can provide.
UPDATE: February 2, 2019
Nakamichi for the last month has been providing owners of the 9.2 with the firmware upgrade. After the announcement, I purchased a Panasonic DP-UB820 4K player since Oppo went out of business, and I wanted a good player with Dolby Vision.
With the Nakamichi 3.0/3.1 firmware, it does indeed let you use Dolby Atmos and Dolby Vision now, however there's problems, and it's a problem with ARC, Roku, and 4K discs.
With the new Dolby enabled firmware, there's a 5~7 second audio delay. I've also had issues with audio suddenly sounding like it's coming out of a tin can. Nakamichi has stated there could be random audio drop outs as well, and users on AVS Forum have complained about it.
That said, I downgraded back to the 1.0c firmware, the last update before the Dolby upgrade. If Nakamichi fixes the issues, I'll return to it. With or without the Dolby Atmos/Vision update, I still say the best soundbar you can get, and the best you can do without getting a real home theater system.
