Nakamichi hit a home run!
After6.5 yrs, my Nakamichi 9.2.4 s HDMI(Atmos) quit working. I tried using a Coaxial cable. The sound was good but not great. I had wanted the 11.2.6 wireless. However I couldn’t make the soundbar fit. So I settled for the Shock Wave 9.2.4earc. It was on sale at a very good price. I didn’t expect much improvement from my 9.2.4.;To my surprise I went from really good sound to excellent! The power, clarity, and ease of use make this dynamo an incredible buy! The eEarc worked flawlessly with my 4 k dvd player Even the remote is a huge improvement. The remote is infrared, more organized, and much easier to see. In summary 1300 watts, Atmos, DTSX, SSEMax and all the power you could ever want; It is incredible, Buy it! You won’t be disappointed!

OMG, welcome to the theatre
I’ll start by saying that I upgraded from the Nakamichi elite 7.2 system with two surround speakers and two 8″ subs (older model from 3-4 years ago), to the Ultra 9.2.4 (newest model just behind the dragon) and I’m comparing the two, and wow…. What a difference. This is long, but if you are trying to decide if spending the extra cash is worth it, I hope this helps.Bass – the bass is felt vs being heard. The Ultra has very deep bass that shakes the room, just like your favorite theater experience. The elite with the dual 8″ subs were great, but the balance of sound vs bass coming out of them was just slightly off. I didnt feel this way until I heard the 10″ subs and then I really noticed. You would hear what sounded like muffled voices trying to come through the speakers from the elite. I’m a big bass lover when I watch movies. If you like that rattle your windows, feel it in your toes kind of rumble, go with the Ultra. Great power without the voice distortion.Clarity- the highs are so much better with the Ultra. My dad who is hard of hearing commented on the clarity the first time he heard the system. He could actually hear it all, even with the system being turned down a bit. I really had to crank up the elite to get the clarity. That could be due to the 8″ subs always drowning the highs out slightly with too much sound coming through them instead of rumbling low bass. It was a catch 22, I wanted to feel the bass, but by turning it up it would drown out a bit of the highs. It just wasn’t as balanced. I think I was looking for too much bass out of the elite. That’s on me. The elite is more than enough for 90% of home viewers.Surround- this system makes movies so much fun. It’s truly a theater experience. I can’t tell you how many times someone has looked over their shoulder looking for the noice they just heard. It takes scary movies to the next level. If you are a gamer, you can tell what direction something is coming from and respond as needed. Behind you, next to you, in front of you… Very emersive. Yes there are wires, so there’s limitations on how you set it all up depending on your room.Connectivity- this was the game changer. The elite had issues with the Bluetooth from the sound bar to the subs, which means connectivity issues from the sub to the rear speakers. Most of the time it was a non issue. Other times it was maddening and because it was unpredictable, you just never knew what to expect. It is what drove me to the Ultra to be honest. That crackle of the rear speakers and distortion of bad as it would momentarily disconnect drove me insane and nothing seemed to fix it. Though I never changed the frequency that my router ran on (Nakamichi recommended) and to be honest, I shouldn’t have to. When my family replaced their cell phone’s and we were working on transferring data and updating to current software, the elite was rendered almost useless during that time. We also often had to keep the cellphones in the other room to limit any potential Wi-Fi disruption. Crackle, crackle, crackle, went the rear speakers and talk about a very distracting thing to be happening during your favorite F-18 dog fight scene in Top Gun Maverick. The Ultra has had zero issues with connectivity regardless of the phone or router placement. Huge win for Nakamichi. I’m sure the newest elite models have corrected this issue, mine was older.Elite will give you the small town theater experience. Great value, big sound, solid bass, but it takes more adjusting settings to get the most out of it.Ultra will give you more of the iMax experience. Big sound, ease of use with sound settings, and you will feel like you are in the storm vs watching the storm through a window.

Stop. Just buy it.
Before we even get to the soundbar itself, the customer experience needs to be highlighted. I received several communications from Nakamichi before I even installed the system, each providing detailed information about what to expect, how to install, and how to configure the system. Their configuration tool asks you to input the other equipment you are using and then spits out how to connect them all. It could not be simpler. On their site they even give you a guide on what streaming boxes, game consoles, etc will spit out Dolby Atmos, even down to the detailed level of what App on what box will do what. Its information i couldn’t even get from Roku. They will also have direct links, from their system configuration site to any and all accessories needed to complete your setup(speaker stands, streaming boxes, etc). From the first second, they want you to have all the information you need and make the entire process as easy and straightforward as possible.As for the performance. It’s by far the best system i’ve ever used. Sound is amazing, and the cable runs to the Side and surround speakers is much longer than i need(32′). I haven’t had time fully fleshing out all the features and capabilities, but right out of the box, it’s been excellent with almost no tweaking. The 2 subs have not been overpowering, and actually provide an excellent amount of bass, yet do not shake our walls unnecessarily like our Vizio Elevate sub does. Dialogue, even on movies/shows where it sometimes is subdued on our other system(Vizio Elevate, Quite good itself, but not close to this one) is clear and discernible. The system does a good job balancing the direct audio and the surround so that one isn’t overpowering when it shouldnt be.The system includes ALL the hardware you need to wall mount the speakers, the remote, Duracell abtteries for the remote(not cheap Chinese batteries) 32′ cables to connect the 4 surround speakers to the subs, an optical cable, a certified Ultra High Speed HDMI cable, and a 3.5mm headphone cable. All of the included hardware is solid in build(as is the system itself). On top of all of this, lays a 4ft long cardboard setup guide. It lays out, step by step, how to connect the system, and multiple QR codes that link to their tech support website that has guides that are even more detailed. They flood you with information to help you setup(which for those who need it, is VERY clear and simple to understand). For the price, one would really expect the ancillary stuff to be cheap. Nakamichi really pays attention to the details, and seems to understand that their customer ranges from the AV pro to the novice and their information covers the entire spectrum.This system would be well worth it even if the price was substantially higher. As priced, its a home run.

Pretty darn good but not great
Setup was easy and it worked out of the box. I read the instructions and changed settings to fit my needs.I use the all channel stereo for playing music over Bluetooth and it gets pretty loud and sounds good.I’ve watched a couple movies via Chromecast and Disney+, sounds good but I wasn’t really paying attention to the surround.For the price, it has some issues that shouldn’t exist.-The power cable doesn’t fit and has to bend out of the bar is sitting on a surface. Mounted on a wall it could come out of the bottom. It should fit regardless.-Surround speakers have quiet static when nothing is playing. No audio signal should equal no signal to the speakers.-Does sometimes sound like a tin can on certain media. However, it does have the tr+/- buttons and I adjusted the treble way down. Seems to help.-Included cables are cheap AF. The RCA’s and power cables are the type you get with the lowest cost cheapest electronics.
